parsed != compiled. Use Py_CompileString instead. The resulting code  
object may be executed with PyEval_EvalCode.

BTW, instead of looking at some random web site, it's better to read the  
official documentation at http://docs.python.org. You should have a copy  
of it in the Doc subdirectory inside your Python installation.
