Python 3.11 is a version of the Python programming language, created by Guido van Rossum in the late 1980s, with the first version released in 1991. Python is a high-level, general-purpose language known for its emphasis on code readability, achieved through the use of significant indentation. It's dynamically typed and garbage-collected, supporting multiple programming paradigms like object-oriented, procedural, and functional programming.
Python 3.11, released on October 24, 2022, includes several new features and optimizations. Key improvements include increased performance speeds (between 10% and 60% faster than Python 3.10), more informative error tracebacks, and improved exception handling. It also boasts better handling of recursion, faster startup times, and new typing features. As of February 2026, the Python Software Foundation supports several versions of Python, including 3.11. Python is free to use.
