My early contributions to https://github.com/jart/cosmopolitan were focused towards getting a single-file Python executable. I wanted my Python scripts to run on both Windows and Linux, and now they do. To try out Python, you can:

    wget https://cosmo.zip/pub/cosmos/bin/python -qO python.com
    chmod +x python.com
    ./python.com

Adding pure-Python libraries just means downloading the wheel and adding files to the binary using the zip command:

    ./python.com -m pip download Click
    mkdir -p Lib && cd Lib
    unzip ../click*.whl
    cd ..
    zip -qr ./python.com Lib/
    ./python.com # can now import click

Cosmopolitan Libc provides some nice APIs to load arguments at startup, like cosmo_args() [1], if you'd like to run the Python binary as a specific program. For example, you could set the startup arguments to `-m datasette`.
