What are the differences between Python 2 and Python 3?

Python 2 and Python 3 are two distinct versions of the Python programming language. Python 3 introduced several changes and improvements over Python 2, including changes to the print statement, Unicode handling, and syntax. Some notable differences include:

  • In Python 2, the print statement is used without parentheses, while in Python 3, it is used as a function with parentheses.
  • Python 3 enforces stricter Unicode handling by default, whereas Python 2 treats strings as sequences of bytes.
  • Python 3 introduced the yield from syntax for delegation in generators.
  • Python 3 removed some deprecated features from Python 2 and introduced new features like f-strings for formatted string literals.

It’s important to note that Python 2 is no longer actively maintained, and Python 3 is the recommended version for new projects.
