Wrapping Go in Python
summary
Shows exactly how to compile a Go file into a shared object with go build -o name.so -buildmode=c-shared, load it from Python with ctypes.cdll and call the exported function by its exported name. Integers and floats round-trip with implicit or simple C type mapping, booleans appear as 0/1, strings require explicit conversion with C.CString/C.GoString and appear as bytes, and lists/dicts do not auto-convert. Example uses goroutines and channels to speed a prime counter; full code is on GitHub.
