Hi.

Python has lots of libs which you can include with "import", right? And the language itself has about 250 functions. Are all those libs for Python also written with pure Python and it's 250 functions?

No. Many are written partly in C.

Many of the Python libraries you speak of are nothing more than wrappers for C/C++ libraries (called Python bindings), for example pygame is a binding to SDL, .
Also, it is common practice in Python to write modules in C for better performance, which then are used in Python programs, like NumPy.

Just a tip in along the same lines: check out Swig if you're interested in writing C/C++ extensions for Python, and other dynamic languages.

I love Python. It's a great language and the community behind its vast number of libraries tend to write more robust libraries, in comparison to another scripting language I am familiar with: PHP.

But nothing beats C (and to a certain extent Java nowadays) for its speed. But then languages like Python can be used to build things much faster than with Java or C, and Python has amazing bindings to some of those more complex libraries you find in C/Java.

Something I've found out recently is the Kivy library for python that allows you to code cross platform GUIs including for the smartphone OS's! So you get to write code much faster and also use the more powerful C libraries underneath the hood.
