I don't think you can use PyArg_ParseTuple() like this (in a series of 
"if" statements, as in Method_Create); whenever it fails "it returns 
false and raises the appropriate exception", so even if the first one 
fails and the second one succeeds, there's an error exception set 
somewhere which you need to get rid of.
