If I understand correctly:

- you are creating one class (not several similar classes)
- this class has several very similar functions
- you (understandably!) don't want to write out these very
   similar functions one at a time

If that is all correct, then, as Random suggested, move that loop into 
the class body and use locals() [1] to update the class dictionary. 
Just make sure and delete any temporary variables.

Your other option is to put the code in a class decorator.

     Yes, returning the class namespace is a language gaurantee.
