As the Python/C API Reference Manual, Section 2. The Very High Level Layer 
says:

"""
int PyRun_SimpleString (char *command) 
Executes the Python source code from command in the __main__ module. If 
__main__ does not already exist, it is created. Returns 0 on success or -1 
if an exception was raised. If there was an error, there is no way to get 
the exception information. 
"""

In other words, PyRun_ stuff is pretty much only good for side effects. If 
you want to get results or poke around, you have to get your hands dirty.

BTW, only the first include is required.
