Dict/List manipulation from C

dict1 = dict2 just makes a new reference to the old dictionary, which is
not what you're describing with your loop.

I think the PyDict_Copy function does what you want.  Something like

PyObject *NewDictionary;
NewDictionary = PyDict_Copy(OldDictionary);
if (!NewDictionary) {return NULL};

Why do you want to do this on the C side?  Wouldn't 

sys.path = [my_two_entries]

be much easier?
