2) Which is the following statement is incorrect regrading data types present in Python language?

  1. Python have major 5 data types.
  2. Python tuples are sub data type of sequence data type.
  3. Complex numbers are not a sub data type form in Python data types.
  4. Integer value are stored as integer class type which is a sub data type of Numeric data type.
Answer: c. Complex numbers are not a sub data type form in Python data types. Explanation: Python have major 5 data types i.e., Numeric, Dictionary, Boolean, Sequence type and Set. Further Numeric and Sequence data type have sub data type forms i.e., Integer, Float & Complex Numbers for Numeric data type and Tuple, String & List for Sequence data type. Therefore, Option C is incorrect statement and it is the right answer.

3) Which one of the following is not a Python keyword?

  1. except
  2. finally
  3. calender
  4. return
Answer: c. calender Explanation: Except for 'calender' all other three i.e., 'except', 'finally' and 'return' are reserve keywords in Python and we cannot use them to define variable in our program. Therefore, Option C is the right answer.

4) Which is the following is an Arithmetic operator in Python?

  1. // (floor division) operator
  2. & (binary and) operator
  3. ~ (navigation) operator
  4. >> (right shift) operator
Answer: a. // (floor division) operator Explanation: The. // (floor division) is a type of arithmetic operator in Python. All other three options are types of bitwise operator in Python. Therefore, Option A is the right answer.

5) Which one of the following is the correct statement regarding comments in Python?

  1. Python provides us a way through which can do both single line and multiple lines in our program.
  2. Python comments will affect the print statement present in program at some extent.
  3. To apply comment we have to use '#' keyword at starting while writing a comment in our program.
  4. To apply comment we have to use '#' keyword both at starting and ending while writing a comment in our program.
Answer: c. To apply comment, we have to use '#' keyword at starting while writing a comment in our program. Explanation: Whenever we will use comments in our Python program, we have to use '#' only at the starting of the comment that will indicate to Python that this line is a comment and Python will not interpret it. Hence, Option C is the right answer.

6) Which of the following is not an advantage of defining function in our Python program?

  1. We can track a large Python program very easily when the given program is splitted into multiple functions inside the code.
  2. Python functions are not reusable and hence we have to define them again and again while using it.
  3. When we use functions in our Python program, we can avoid writing the same logic again and again and call the function every time.
  4. We can call a function many times inside the program and we can call it wherever we want inside the function.
Answer: b. Python functions are not reusable and hence we have to define them again and again while using it. Explanation: The biggest achievement of defining a function in our Python program is the reusability of the function. We can use the function many times in the program and it will imply the same logic every time we call it. That's why defining a function in our Python program saves a lot of time. Hence, Option(B) is the right answer.

7) Look at the following Python program:

given_number = 24
if given_number==10:  
  print("The given number is equals to 10 define in the condition")  
elif given_number==20:  
  print("The given number is equal to 20 define in the condition");  
elif given_number==30:  
  print("The given number is equal to 30 define in the condition");  
else:  
  print("The given number is not equal to any of 10, 20 or 30 define in the condition");
What will be the output of the above program?
  1. 10
  2. 30
  3. not equal to any of 10, 20 or 30
  4. 20
Answer: c. the given number is not equal to any of 10, 20 or 30 define in the condition Explanation: In the above code, we have defined a number 24. When Python loops through the condition, it will check if any of the define condition satisfied from elif statement otherwise it will print what's defined in the else statement. In this program, since given number is not equal to any of 10, 20 or 30 it will not satisfy any condition and print what's defined in the else statement. Hence, Option(C) is correct answer.

8) Look at the following Python program:

# three integer numbers
x = 24
y = 26
z = 31
if x>y and x>z:  
    print("The largest of the given three integer numbers is x:"x);     
if y>x and y>z:  
    print("The largest of the given three integer numbers is y:"y);      
if z>x and z>y:  
    print("The largest of the given three integer numbers is z:"z);
What will be the output of the above program?
  1. The largest of the given three integer numbers is x: 24
  2. The largest of the given three integer numbers is y: 26
  3. The largest of the given three integer numbers is z: 31
  4. Syntax Error
Answer: c. The largest of the given three integer numbers is z: 31 Explanation: In the above code, we can see that three integer numbers are defined and through the if statement we are comparing these numbers to find out which one is biggest number. So, when Python compile the code and check every condition. If the condition satisfies in first if statement then Python will print the output otherwise it will go to second if statement, similarly Python will go to third if statement in the program. Here, the condition given in if statement will satisfy and Python will print the output. Hence, Option C is the correct answer.

9) Look at the following Python program:

Marks_of_student = 57
if Marks_of_student > 80 and Marks_of_student <= 100:  
   print("Congratulations mate ! You have scored grade A in your final exams ...")
elif Marks_of_student > 60 and Marks_of_student <= 80:  
   print("Congratulations mate ! You have scored grade B in your final exams ...")
elif Marks_of_student > 40 and Marks_of_student <= 60:  
   print("You need to improve ! You have scored only grade C in your final exams ...")
else:
        print("You need to improve very hard ! You are failed in your final exams ...")
What will be the output of the above program?
  1. You need to improve very hard ! You are failed in your final exams ...
  2. Congratulations mate ! You have scored grade B in your final exams ...
  3. Congratulations mate ! You have scored grade A in your final exams ...
  4. You need to improve ! You have scored only grade C in your final exams ...
Answer: d. You need to improve ! You have scored only grade C in your final exams ... Explanation: As we can see in the above code, we have given marks of a student. In the program, elseif statement is used for grading according to the marks is given. When we run the program, Python will check every condition and in which condition the marks satisfy Python will print the output and if not, then Python will move to next condition. If none of condition is satisfied then Python will print the last statement given in program. But in this program, the third condition will satisfy and Python will print statement given with it. Hence, option D is the right answer.

10) Which of the following operation cannot be performed on a Python string?

  1. Deletion of Python String
  2. Splitting of Python String
  3. Adding elements in a Python String
  4. Reassigning of Python String
Answer: c. Adding elements in a Python String Explanation: Except for adding elements in string, we can perform all the operations given in the option. When we try to add more element in an already existing string, Python will throw an error in the output but we can complete replace or reassign the string. Hence, option C is the right answer.

11) Which string method is used to check if all the given characters in a Python string defined in our program are alphabets?

  1. isalpha()
  2. isalnum()
  3. isdigit()
  4. islower()
Answer: a. isalpha() Explanation: Whenever we need to check if the string, we have defined in our program is only contain alphabets in it, then we will use isalpha() method and place the defined string between the brackets. If the string has all the alphabets in it, it will print true in output otherwise it will false in the output. Hence, option A is the right answer.

12) Which string method is used to check if all the given characters in a Python string defined in our program are in lower case?

  1. isnumeric()
  2. islower()
  3. isdigit()
  4. islower()
Answer: b. islower() Explanation: Whenever we need to check if the string, we have defined in our program is only contain lower case alphabets in it, then we will use islower() method and place the defined string between the brackets. If the string has all the lower-case alphabets in it, it will print true in output otherwise it will false in the output. Hence, option B is the right answer.

13) Which of the following Python identifier is correctly defined as well as have highest readability?

  1. 1Nick
  2. _2_Jonas
  3. Table
  4. it_is_tablefor2
Answer: c. Table Explanation: Except for Option A (1Nick) all the other three options are correctly defined identifiers in Python but option C have highest readability among all three. Hence, Option C is the right answer.

14) Which of the following is not a token defined in Python?

  1. Keywords
  2. Comments
  3. Literals
  4. Operators
Answer: b. Comments Explanation: Python have following four types of tokens defined in it:
  1. Keywords
  2. Literals
  3. Identifiers
  4. Operators
Hence, Option B is the correct answer.

15) Look at the following Python program:

x = "Integer"
print(type(x)
When we run the above program what it will print in the output?
  1. <class 'str'>
  2. <class 'int'>
  3. <class 'float'>
  4. Syntax Error or TypeError
Answer: d. Syntax Error or TypeError Explanation: In the above program, look at the second line of code, we have not closed the print statement and only type statement is closed. Therefore, when we run the program it will show an TypeError or Syntax Error in the output. If we close the print statement in second line of code then the program will print "<class 'str'>" in the output. Hence, Option D is the right answer.

16) Which one of the following is the type of literal collections provided to us in Python?

  1. String literals
  2. Numeric literals
  3. List literals
  4. Boolean literals
Answer: c. List literals Explanation: In Python, we are provided with four types of literal collections which we can use in our program i.e., Tuple literals, Set literals, List literals and Dict literals. Hence, option C is the right answer.

17) Which of the following type of Python operator will only print True or False in output when we use it in our program?

  1. Assignment operator
  2. Membership operator
  3. Arithmetic operator
  4. Comparison operator
Answer: d. Comparison operator Explanation: Comparison operator are used to compare two numbers or identifiers defined in our Python program. It will print true in output only if the given comparison satisfies the condition otherwise it will print false in output. Hence, option D is the right answer.

18) Look at the following Python program:

Python_Set1 = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}
Python_Set1.remove(14);
print(Python_Set1)
What will be the output when we run the above program?
  1. We cannot remove any item from the Python set after we defined it in our program.
  2. Program will be run successfully and Python will not raise an exception.
  3. 1 2 3 4 5 6 7 8 9 10 11 12
  4. Python will raise an exception and throw an error in the output of program.
Answer: d. Python will raise an exception and throw an error in the output of program. Explanation: In the above program, we can see that a set is defined with number 1 to 12 but in second line we are trying to remove element 14 from the set that is not present in the set. As per the property of remove() method, if we try to remove an element from the set that is not present in the set then it will throw an error in the output. Hence, Option D is the right answer.

19) Look at the following Python program:

Python_List1 = [1, 2, 3, 5, 7, 11, 13, 17, 19, 23]
Python_List1.insert(29)
print(Python_List1)
What will be the output when we run the above program?
  1. 1 2 3 5 7 11 13 17 19 23
  2. 1 2 3 5 29 7 11 13 17 19 23 (element inserted randomly at any place)
  3. 1 2 3 5 7 11 13 17 19 23 29
  4. Type Error will show in the output
Answer: d. Type Error will show in the output Explanation: In the above program, an element is inserted in the pre-defined Python list in the program using the listname.insert(a,b) method. The listname.insert(a,b) method requires both argument a and b to run the method. In this method, 'a' defines the position in which the element will be added in the list and 'b' represents the element that is to be added in the list. If we don't give both arguments(a,b) while using listname.insert(a,b) method, Python will show a TypeError in the output. Hence, Option D is the right answer.

20) Look at the following Python program:

k = 24;  
while k:  
    print(k," ",end=""),
    k=k+1;  
    if k == 36:  
        break;
print("The program is now came out of while loop after running successfully");
What will be the output when we run the above Python program?
  1. The given loop is infinite loop
  2. 24 25 26 27 28 29 30 31 32 33 34 35
  3. 24 25 26 27 28 29 30 31 32 33 34 35 The program is now came out of while loop after running successfully
  4. Syntax Error
Answer: c. 24 25 26 27 28 29 30 31 32 33 34 35 The program is now came out of while loop after running successfully Explanation: In the above program, we have given k is defined equals to 24 and while loop is used on it. When k will enter in the loop, it will iterate until it reaches to 36 where it satisfies break statement. When the break statement satisfies, it will print the statement given with break and exit the loop. Hence, option C is the right answer.

21) Look at the following Python program:

Python_list = [3,4,5,6,7,8,9,10]  
count_index = 1;  
for k in Python_list:  
    if i == 8:  
            print("The given item is matched in the program")
            count_index = count_index + 1;  
            break
print("We found the given item at",count_index,"location in the given list of program");
What will be the output when we run the above program?
  1. The given item is matched in the program We found the given item at 7 location in the given list of program
  2. The given item is matched in the program We found the given item at 6 location in the given list of program
  3. The given item is matched in the program We found the given item at 3 location in the given list of program
  4. The given item is matched in the program We found the given item at 5 location in the given list of program
Answer: b. The given item is matched in the program We found the given item at 6 location in the given list of program Explanation: In the above program, a Python list is defined with a variable name count_index. A for loop is used on the list to match the given item from the list. As many times the loop continues, the value of count_index increases within the loop. Since 8 elements will match at when loop will run 6 time, the output will be item is matched at 6 location in the program. Hence, Option B is the right answer.

22) Look at the following Python program:

String_mkr = "TUTORIALANDEXAMPLE"  
for i in String_mkr:  
    if(i == 'D'):  
            continue
    print(i)
When we run the above program, which alphabet from "TUTORIALANDEXAMPLE" string from the program will not printed in the output?
  1. T
  2. R
  3. D
  4. E
Answer: c. D Explanation: As per the property of continue statement in Python, when the condition given with continue statement satisfied the continue statement will skip the loop and not print the output at particular condition and continue loop. So as in the above program, when the string "TUTORIALANDEXAMPLE" iterated through for loop and print each alphabet separately. But when iteration reach at letter D, it will satisfy the if condition and according to the property of continue statement letter D will not be printed in the output. Hence, option C is the right answer.

23) Look at the following Python program:

k = 0                     
while(k < 14):                
   k = k+2
   if(k == 10):  
      continue
When we run the above program, which of the following number will not printed in the output?
  1. 10
  2. 8
  3. 12
  4. 6
Answer: a. 10 Explanation: In the above program, we have defined an integer variable k equals to 0. We have used while loop on the variable with if condition in it. Every time the loop runs, the variable increases by 2 and prints in the output. But when k becomes 10, if condition given in the program satisfies and according the property of continue statement, the integer 10 will not be printed in the output. Hence, Option A is the right answer.

24) How Python Sets are different from those FrozenSets defined in our program?

  1. Python Sets and FrozenSet are defined very differently in a Python program.
  2. We can add items in Python sets but we cannot add items in FrozenSets.
  3. We can remove items from Python sets but we cannot remove items from FrozenSets.
  4. All of the above
Answer: d. All of the above Explanation: We can define Python sets through two methods whereas FrozenSets are defined through only one method. Python sets are mutable in nature i.e., we can perform addition, deletion etc. operations on Python sets but FrozenSets are immutable in nature i.e., no operation is performed on them. Hence, option D is the right answer.

25) Why 'pass' keyword is use in a Python program?

  1. Pass keyword is use to exit the given program.
  2. Pass keyword is use to execute nothing.
  3. Pass keyword is use to stop the execution of loop.
  4. Pass keyword is use to exit the given loop in program.
Answer: b. Pass keyword is use to execute nothing. Explanation: In Python, we use Pass keyword when we have to execute nothing from the given loop at given condition. Hence, option B is the right answer.

26) Look at the following Python program:

Python_list = [1,2,3,4,5,6,7,8,9]
for k in Python_list:   
    if(k==7):  
        pass  
        print("This is the pass block statement in program:",k)
What will be the output when we run the above program?
  1. This is the pass block statement in program: 1 2 3 4 5 6 7 8 9
  2. This is the pass block statement in program: 1 2 3 4 5 6 8 9
  3. Syntax Error or TypeError
  4. This is the pass block statement in program: 7
Answer: d. This is the pass block statement in program: 7 Explanation: In the above program, a Python list is defined and for loop is used on it for iteration of elements in the list. When the if condition defined inside the for loop at 7, the pass statement will execute and it will print the statement given in next line of code with it. Hence, option D is the right answer.

27) A Python tuple that is created without using the parentheses brackets () is called as?

  1. Tuple sampling
  2. Tuple packing
  3. Tuple sorting
  4. None of these
Answer: b. Tuple packing Explanation: In Python, a tuple that is created without using the parentheses bracket () while defining it also called as Tuple packing. Hence, option B is the right answer.

28) Which of the following is the right method through which we can create an empty tuple in our Python program?

  1. Empty_Tuple = Null
  2. Empty_Tuple =
  3. Empty_Tuple = ()
  4. Empty_Tuple = 0
Answer: c. Empty_Tuple = () Explanation: If we want to create an empty tuple in a Python program, we have to pass no argument inside the parentheses () while defining the tuple just like Empty_Tuple = (). Hence, option C is the right answer.

29) Which one of the following option is the right description for '\b' escape sequence used with a string in the Python program?

  1. '\b' escape sequence represents ASCII Backspace (BS)
  2. '\b' escape sequence represents ASCII Backline (BL)
  3. '\b' escape sequence represents ASCII Break
  4. '\b' escape sequence represents ASCII Backup
Answer: a. '\b' escape sequence represents ASCII Backspace (BS) Explanation: While working with strings in our Python program we use many escape sequences and use them in our code. The '\b' when used work as backspace function while printing the output. It deletes a space from string in print statement. Therefore, \b represents ASCII Backspace (BS) in Python strings. Hence, option A is the right answer.

30) How Python lists are different from those Python tuples?

  1. Python lists are represented by square brackets [] whereas Python tuples are represented by parentheses brackets () in our Python program.
  2. Python lists are immutable in nature whereas Python tuples are mutable in nature.
  3. Debugging a Python list is very easy as compare to a Python tuple.
  4. Python lists are more memory efficient as compared to Python tuples.
Answer: a. Python lists are represented by square brackets [] whereas Python tuples are represented by parentheses brackets () in our Python program. Explanation: Python lists are defined in a square bracket [] but Python tuples are defined in parentheses. Python lists are mutable in nature whereas Python tuples are immutable. Therefore, Python tuples are more memory efficient as compared to Python lists because of their immutable nature. And because Python tuples are immutable, they are easy to debug as compared to Python lists. Hence, option A is the right answer.

31) Which of the following is not a built-in function for Python dictionary?

  1. str(DictionaryName)
  2. len(DictionaryName)
  3. cmp(Dictionary1, Dictionary 2)
  4. DictionaryName.items()
Answer: d. DictionaryName.items() Explanation: Except for DictionaryName.items(), all other three options are built-in functions in Python available for Python dictionary whereas DictionaryName.items() is one of the built-in methods in Python available for Python dictionary.

32) What will happen when we print a Python function defined in our Python program without defining return statement inside the function?

  1. Python will show a TypeError when we run the program
  2. Python will print None in the output
  3. Python will run the program successfully without showing an error
  4. Python will show syntax error when we run the program
Answer: b. Python will print None in the output Explanation: When we define a function in our Python program without defining return statement inside the function, it will print 'None' when we use the function in the print statement.

33) Look at the following Python program:

def sum_function():  
    x = 24  
    y = 26  
    z = x+y
    z = 72  
    return z
print("The output of program is:",sum_function())
What will print in the output when we run the above Python program?
  1. The output of program is: 50
  2. The output of program is: 72
  3. Syntax Error
  4. The output of program is: 132
Answer: b. The output of program is: 72 Explanation: In the above program, when Python will interpret the lines of code, it will first assign the sum of x and y variable to z variable and in the next line of code, Python will assign 72 to variable z. So, when we call the sum_function in the print statement, it will print z as 72 in the output. Hence, option B is the right answer.

34) Look at the following Python program:

Number1 = -31
Number2 = 3.147
print(abs(Number1))
print(abs(Number2))
What will print in the output when we run the above Python program?
  1. -31 3.147
  2. Syntax Error
  3. <class'Integer'> <class'Float'>
  4. 31 3
Answer: d. 31 3 Explanation: The abs() is a built-in function class ‘Float inside Python. This function is used to get the absolute value of the variable that we have defined in our program. It will ignore all the signs and value after decimals to print the absolute value of the variable. Hence, option D is the right answer.
