Python 2 and Python 3 differ significantly in syntax and functionality. One of the most notable differences is the print statement—Python 2 uses it without parentheses, while Python 3 treats it as a function. Python 3 also uses Unicode by default for text strings, whereas Python 2 handles them as ASCII unless specified. Additionally, integer division behaves differently, with Python 3 providing more accurate results.

Python 3 supports better library compatibility and modern features, making it the recommended version for all new projects. Python 2 reached its end of life in 2020 and no longer receives updates or support.
