   I ithink it is correct. Why do you think it is not?

   Define your procedure:

;---fprot.py
def overrideme(self, str, someint):
   pass

;--fimp.py
import fprot

   And assign your override function:

fprot.overrideme = my_override

   After this, call fprot.overrideme from any place (C or Python).
