Python vs Python 3: What’s the difference?

Python has evolved significantly, with Python 3 bringing major improvements over Python 2. While Python 2 reached end-of-life in 2020, Python 3 is the actively maintained version, offering better performance, enhanced syntax, and improved security.

Key differences include print statements changing from a keyword to a function, improved Unicode support, and type hints for better readability. Python 3 also introduces asyncio for efficient concurrency, a more powerful f-string syntax, and enhanced memory management. If you're starting a new project, Python 3 is the way to go, as most modern libraries no longer support Python 2.

Key takeaways:

• Python 2 is deprecated, while Python 3 is actively maintained.

• Syntax improvements, including changes in

• Better Unicode handling: Python 3 uses UTF-8 by default, making text processing more efficient.

• Enhanced performance: Python 3 optimizes memory usage and execution speed.

• Modern features: Supports async programming, f-strings, and type hints.

• Library support: Most modern libraries no longer support Python 2.
