How to inherit one class implement by C

Question

I want to add method for one class implemented by C

from lru import LRU
class A(LRU):
    def foo(self):
        print("a")

lru is a lib from https://github.com/amitdev/lru-dict

error:“type ‘type’ is not an acceptable base type”

if you compile LRU by yourself, then you could use: ctypes.cdll.LoadLibrary() to load the library. Not sure if this works, but worth the try! — albertoperdomo2

Writing Python's inheritable C/C++ types is contained in this PEP 253. Also, you have this guide that explains how to write inheritable types in C/C++.

This is basically a link-only answer, which is frowned upon on Stack Overflow. It would be better to explain why this type isn't inheritable, and refer to the PEP or guide if needed.
