Python 2 and Python 3 and it's Difference | Python Programming

Python is also an interpreted scripting language. Guido van Rossum is a great creator of the Python programming language and is the founder of Python programming which made Python is world-famous in the programming field. Our tutorial covers all topics of Python programming such as Installation, Control statements, Strings, Lists, Tuples, Dictionary, Modules, Exceptions, Date and Time, File I/O, Programs.

Python is a general-purpose, dynamic, high level and interpreted programming language which supports an object-oriented programming approach to develop applications. It is easy to learn and also provides many high-level data structures.

Python is easy to learn, powerful and versatile scripting language that makes it attractive for application development. Python's syntax and dynamic typing along with its interpreted nature make it an ideal language for scripting and rapid application development.

 

Python supports many programming patterns, including object-oriented, imperative, and functional or procedural programming styles. Python is not intended to work in any particular field, such as web programming, that's why it is known as a multipurpose programming language because it can be used with web, enterprise, 3D CAD etc.

We don't need to use data types to declare variables as it is dynamically typed so that we can write a = 10 to assign an integer value to an integer variable. Makes Python development and debugging faster because there is no compilation step involved in Python development, and the edit-test-debug process is much faster.

In most programming languages, whenever a new version is released, it supports the features and syntax of the existing version of the language, therefore, it is easy for projects to switch to the new version. However, in the case of Python, the two versions Python 2 and Python 3 are very different from each other.

Python 2 uses print as a statement and "something" is used as print to print a string on the console. On the other hand, Python 3 uses print as a function and print("something") to print something on the console.

Python 2 uses the function raw_input() to accept user input. It returns a string representing the value, which is typed by the user. To convert it to an integer, we need to use the int() function in Python. On the other hand, Python 3 uses the input() function which automatically interprets the type of input entered by the user. However, we can cast this value to any type using primitive functions (int(), str(), etc.)

In Python 2, ASCII is known by the implicit string type, whereas, same as in python 3, the implicit string category exists Unicode.

Python 3 does not include Python 2's xrange() function. xrange() is the variant of range() function which returns an xrange object which works similar to Java iterator. range() returns a list For example the function range(0,3) contains 0, 1, 2

A small change has also been made in exception handling in Python 3. It defines a keyword that needs to be used.

So friends, today we have discussed Python 2 and Python 3. Like this, we will discuss everything about Python and Other Languages too.
