It's a trick to speed up debugging in the interactive interpreter, and when something goes wrong, you exit the interpreter and try again. > class derivedClass(baseClassMod): > def dFunction(self): > print "We are in a derived Class" > > buwhen I'm trying to run derivedClass.py I get this error : Again, what are you actually doing?
