There must be something more to your problem than what you described.
The following executes just fine for me (ditto if NewKoke is a subclass of object instead of list, and no matter whether I define __getitem__ or not [a guess based on your remark about 'multiply a sequence']):
$ python dubois.py sausages vegetable-style breakfast patty sausages vegetable-style breakfast patty
On Win98 2.2.1, cut and paste into interactive window outputs sausages vegetable-style breakfast patty sausages []
class Klassic: def __imul__(self, other): return "sausages" def __getitem__(self, i): return None
class NewKoke(list): def __imul__(self, other): return "vegetable-style breakfast patty" def __getitem__(self, i): return None
k = Klassic() o = NewKoke()
k *= 1 o *= 1
print k, o
k = Klassic() o = NewKoke()
k *= "spam" o *= "spam"
Because line above gives TypeError: can't multiply sequence to non-int
print k, o
Maybe something has been 'fixed' since then. Terry J. Reedy
