Answer 1

You will receive the process ID of the newly created process when you create it. At least, you will if you used fork() (Unix), posix_spawn(), CreateProcess() (Win32) or probably any other reasonable mechanism to create it.

If you invoke the "python" binary, the python PID will be the PID of this binary that you invoke. It's not going to create another subprocess for itself (Unless your python code does that).
