Python Program to Find the Greatest Among Three Numbers

Python Program to find the greatest among three numbers

We have many approaches to get the largest of three numbers, and here we will discuss a few of them. This python program needs the user to enter three numbers. Next, Python will compare these numbers and print the greatest among them.

Input: A = 4, B = 6, C = 8  Output: C is the greatest

Method 1: By using Python Elif Statement

#Program to find the greatest among three   
#Take three number from user to compare 
num1 = int(input("Enter first number: ")) 
num2 = int(input("Enter second number: "))
num3 = int(input("Enter third number: "))
#compare the number 
 if (num1 > num2 and num1 > num3): 
 print("{0} is Greater Than both {1} and {2}". format(num1, num2, num3)) 
elif (num2 > num1 and num2 > num3):           
print("{0} is Greater Than both {1} and {2}". format(num2, num1, num3)) 
elif (num3 > num1 and num3 > num2):          
 print("{0} is Greater Than both {1} and {2}". format(num3, num1, num2))
 else:      
#Print the result  
print("Either any two values or all the three values are equal")

Output

CASE 1:

CASE 2:

Explanation: In this program, a user will be asked to enter three numbers. This number will be stored in a separate variable. Now, we will compare all three numbers against each other using if...elif...else statement. After the comparison, the greatest among the three numbers will returns and prints on the screen.

Method 2: By using Nested If Statement

This program uses the nested IF statement to find the Largest of Three numbers in Python:

#Program to find the greatest among three     
 #Take three number from user to compare  num1 = int(input("Enter first number: "))
num2 = int(input("Enter second number: ")) 
num3 = int(input("Enter third number: ")) 
#compare the number 
 if (num1-num2 > 0) and (num1-num3 > 0):    
 print("{0} is Greater Than both {1} and {2}". format(num1, num2, num3)) 
else:    
 if(num2 - num3 > 0): 
print("{0} is Greater Than both {1} and {2}". format(num2, num1, num3))   
  else:       
  print("{0} is Greater Than both {1} and {2}". format(num3, num1, num2))

Output

Here is the output:
