What are the exact differences between Python 2 and Python 3?

I couldn’t find a clear information about the differences between these two.

What are the key differences between Python 2 and Python 3, and what impact do these differences have on programming in each version?

if i write print 'hello world' or print('hello world') why is this concern a huge difference for version change?

>Solution :

To Answer your question

well, the difference may not be seems a big change but, In Python 2, the print statement is used without parentheses, as in print 'hello world'. This syntax is easy to read and write, but it has some limitations. For example, it doesn’t allow for multiple arguments to be printed on the same line. there for python3 resolved this issue and many more similar issues.

Addtional Information

Python 2 and python 3 are major version of python programming language.

Python 2 was the first official release in year 2000 and it became aboulete in recent years 2020 and it is no longer used.

On other hand, Python 3 was released in year 2008 to solve the following problems in python two:

• print statement:

  • python2: print function was used without paranthesis. i.e. print 'Hello World'.
  • python3: print function is used with paranthesis. i.e print('Hello World').

• string encoding: in python2 only ascii character were usable where in python3 the default is unicode

• in python3 syntax became more readable.

• python3 became more faster then python2 and many more factors.
