C Extensions (ctypes, cffi)

Python's biggest weakness is also its biggest myth: "Python is slow." It's only slow when a hot loop runs in pure Python bytecode. The moment you call into a C library, you get C-speed work for free. This lesson covers when reaching for C makes sense, the four common ways to do it, and how to use ctypes and cffi to call C code from Python without writing a single line of CPython C-API glue.
