Ruby and Python are incredibly similar in raw functionality, but extremely different in culture. e.g. Both languages allow monkey-patching, while one community thinks it is a great productivity boost making it easy to build cool language tricks, while the other considers it an absolute last resort to be avoided in almost every situation. I think the key point here is that Python prioritized making native add-ons easy, and so it actually developed an ecosystem. The very second sentence on Ruby's C API that is linked above says "the API is huge and largely undocumented."
