For extending CPython (and possibly connecting it to external C
code/libraries) without learning too many new things (Python + a little C
should be enough), you can use ctypes if you can accept the runtime
overhead and the dependency on the ctypes module (which does not exist in
all CPython releases). However, I'd recommend Cython instead, as it gives
you very fast and portable code that works with all CPython versions. And
Cython code is not any harder to write at all.
