I've used angle brackets just for posting here,becauze this forum doesn't support [code][/code] I have a file called baseClass.py with code abouve and indentation is correct. Then I open python IDLE and type : import baseClass as baseClassMod reload(baseClassMod class derivedClass(baseClassMod): def dFunction(self): print "We are in a derived Class" After that i get the error above. But if I paste in Python IDLE a code from baseClass.py and just run: class derivedClass(baseClass): def dFunction(self): print "We are in a derived Class" it works perfectly.
