  summary: General purpose programming language
  description: |
    Python is a widely used high-level, general-purpose, interpreted, dynamic
    programming language. Its design philosophy emphasizes code
    readability, and its syntax allows programmers to express concepts in
    fewer lines of code than would be possible in languages such as C++ or
    Java. The language provides constructs intended to enable clear programs
    on both a small and large scale.

    We provide some meta packages for convenience.
    To get a CPython flavour, use:

        conda install cpython

    To get the freethreading build (i.e. without the Global Interpreter Lock - GIL):

        conda install python-freethreading

    To get the default build (i.e. with the GIL):

        conda install python-gil

    To enable the use of the experimental JIT compiler in CPython:

        conda install python-jit

    or set the environment variable PYTHON_JIT=1. Note that the JIT support
    is available for x86_64 builds only.
