You shouldn't blindly trust those numbers. If you actually read the Python code a lot of them use ctypes to just delegate the work to C. It even says that at the bottom of the page.

Seems like they've finally started calling these out - search for "contentious" on this page:

    i mean, that's what you're supposed to do. python is a glue language, after all.

    Nonsense. You are only "supposed" to do that because if you are using Python and you want performance you have no other choice!

    Reminds me of people saying you aren't "supposed" to store binaries in git - yeah only because git is so bad at it! When we were all using SVN people would have said "you aren't supposed to have multiple people editing the same file simultaneously" as if it were a fundamental truth.

    And Python isn't "a glue language". It's often used like that but there are many many pure Python projects.
