A Better Interactive Interpreter
Python 3.13 introduces significant improvements to the interactive interpreter along with enhanced error messages. The new interactive interpreter now supports colorization, providing a more visually appealing experience. This color support extends to tracebacks and doctest output as well. Users have the option to disable colorization through the PYTHON_COLORS and NO_COLOR environment variables.
Additionally, Python 3.12 includes a basic JIT (Just-In-Time) compiler, as per PEP 744. Although currently disabled by default, this compiler shows promising performance improvements, with plans for further enhancements in subsequent releases.
