Python programming language is one of the most used programming languages, as it is used widely in the field of software and data analysis, web development, etc. It is said to be a user-friendly programing language, as the syntax for it is very simple to write and easy to understand for a beginner programmer. Python programming language is rich in libraries that can be imported easily and used to perform many different operations. In the year 1989, Guido van Rossum is the one who introduced python programming language. It is also used in web applications; web applications like the Django and Flask frameworks are created using python. Compared to any programming language, the syntax in python is much easier.
Python programming language is most widely used language in today’s technology. Many colleges and institutions have introduced python in their syllabus so that the students need to learn python. The biggest advantage of the python programming language is that it has a good collection of libraries widely used in machine learning, web frameworks, test frameworks, multimedia, image processing, and many more applications. The latest version of the python programming language available is python 3 which is the most updated version of the python programming language.
Understanding how data is stored and processed is necessary for data-driven science and computation. This section describes and compares the Python language's default handling of data arrays with NumPy's enhancements. Much of the information in the rest of the book must be understood in the context of this distinction.
Python users are frequently attracted to the language by its simplicity, which includes dynamic typing. A dynamically-typed language like Python omits this specification while a statically-typed language like C or Java necessitates the explicit declaration of each variable.
Integer in Python
They are the negative or non-negative whole integers without a decimal point. Python has no maximum integer size. However, the size of the integer is constrained by the amount of RAM in our system.With 9 or 10 digits of precision, the INTEGER data type may hold whole numbers with a range of -2,147,483,647 to 2,147,483,647.
As a reserved value, the number 2,147,483,648 is not usable. Counts, numbers, and other data are frequently saved in the INTEGER value, which is kept as a signed binary integer.
Integer data is more efficient for arithmetic operations and sort comparisons than float or decimal data. However, INTEGER columns cannot store absolute values above (231-1). A data value is not stored by the database server if it is outside the INTEGER numeric range.4 bytes are needed to store each value for an INTEGER data type.
An unsigned binary number with the least significant byte being 3 and the most significant byte being 0 is used to represent an unsigned integer. The unsigned integer contains only the positive integer, the negative integers are not considered in the unsigned integer data type. We can convert any data type into the integer data type with the help of type conversion method. The int( ) method is used to convert any data type into the integer data type
a = 21.53 b= int( a ) print( type( b) ) print( b)
The python provides the built-in function type( ) which is used to find the data type of the given variable. Here we can observe that, the int( ) data type is used to convert the given variable into our required integer data type.
The unit is an unsigned integer which reads a maximum of 8 bit that is, uint8 reads a maximum number until 255. 8-bit unsigned integers are known as UINT8s (range: 0 through 255 decimal). A UINT8 is not signed, hence its most significant bit (MSB) is not set aside for signing.
Uint8- Unsigned integer( 0 to 255)
An unsigned binary number with the least significant byte being 3 and the most significant byte being 0 is used to represent an unsigned integer. The unsigned integer contains only the positive integer, the negative integers are not considered in the unsigned integer data type. The unit is an unsigned integer which reads a maximum of 8 bit that is, uint8 reads a maximum number until 255
