46. CFFI Usage

CFFI (C Foreign Function Interface) provides a more Pythonic way to call C code.

Example​

from cffi import FFI

ffi = FFI()
ffi.cdef("int add(int, int);")
C = ffi.dlopen("./libadd.so")

print(C.add(2, 3))

Wrap-Up​

CFFI is flexible, easier than writing extensions, and widely used in real projects.
