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. 
Why happen this?
