I've created a library that use t-strings to prevent shell injection that even works on Windows. It's written in Rust. https://github.com/aspizu/tshu

    $ uv run --with tshu python -m asyncio
    >>> from tshu import sh
    >>> username = "aspizu; rm -rf /"
    >>> await sh(t"echo {username}")
    aspizu; rm -rf /
