Compiler The complete source code of a program produced in a high-level programming language is simultaneously translated into machine code (binary code) by a compiler, a specialized tool.

The new interpreter will run Python programs as much as 5% faster, with no changes to existing code required. A beta of Python 3.14 is due in May.

A new JIT compiler, the first no-GIL edition of Python, better errors and typing enhancement, and the removal of dead batteries are all part of Python 3.13.

Python 3.11 will bear the fruits of CPython's multi-year effort to make Python a faster programming language.
