No.  For example, I don't believe there's any way for standard
C-Python to make system calls on Linux.  [Thought ISTR that
somebody has written an extension module that doess that.]

Can you be more explicit?  What sort of "function" are you
talking about?

As for calling functions in libraries, the library doesn't have
to be in C/C++.  Python can make library calls written in any
language (Fortran, Ada, Pascal, etc.) as long as the language
uses a supportted API.  Python can also execute external
programs.
