> Python is insanely fast at data processing and analysis because it has very fast libraries.

It doesn't have fast libraries for everything. E.g. for the use case I brought up, it doesn't (or at least none that I could find at the time). Not all data are homogenous arrays that fit in numpy.

And are those libraries written in Python? Or in C because Python is too slow?

If you take your reasoning, any language that can bind to C (which is pretty much any language) is as fast as C. That is not very helpful when comparing the speed of languages. A slower language will force you to drop into C sooner than a faster one.

> As a matter of fact, don't know if you've heard, but data processing it kind of like.. Python's thing...

Things like audio and video codecs, or crypto code aren't written in Python.
