One reason for Python's popularity (and a reason for many of its quirks ...) is its strong ties to the C programming language. CPython, the reference Python interpreter, allows advanced users to interact with the interpreter's inner workings, and extend the Python language with code written in C.
This talk gives a very high-level overview of the CPython C API, and shows how to build a C extension in a few steps. It then discusses a popular use case for C extensions - optimizing performance of your Python programs! Finally we're gonna look at some modern alternatives to getting more performance out of your Python code, e.g. Cython.
