Extend and Embed Python with C++
summary
Shows exact mechanics: building a PIC shared library, calling it from Python with ctypes, generating wrappers with SWIG, and writing idiomatic bindings with pybind11; demonstrates a native C extension, a SWIG-generated .py/.c wrapper, and C++ class bindings with constructors, methods, inheritance and a __repr__-style printer that actually work. Covers embedding a Python interpreter in a C program, calling Python functions and returning values, discusses GIL workarounds, build hassles and a real-world frozen-Python deployment used for automation.
