Title: Python 3 vs Python 2: A Comprehensive Guide
Introduction:
Python, a versatile and widely-used programming language, has undergone a significant version transition from Python 2 to Python 3. This tutorial aims to provide an overview of the key differences between Python 2 and Python 3, along with code examples to illustrate the changes.
Python 2:
Python 3:
In Python 3, the print statement has become a function and requires parentheses.

Python 3 introduces several improvements and enhancements over Python 2, addressing issues and refining the language. While the transition may require some adjustments, it is recommended to use Python 3 for new projects as Python 2 has reached its end of life. Be mindful of these differences to ensure compatibility and a smooth migration process.
