What do you mean by "I have the PyObject pointers"? Integers and floats  
are immutable in Python. You can't "set" an existing PyIntObject or  
PyFloatObject to another value. But you can create *new* objects from the  
desired values, using PyInt_FromLong and PyFloat_FromDouble.

If this is your first approach to Python, I suggest first become familiar  
with the language, and later try to mix it with C code.
