I'm trying to solve a problem using inheritance and polymorphism in
python 2.4.2
I think it's easier to explain the problem using simple example:
class shortList:
def __init__(self):
self.setList()
def setList(self):
a = [1,2,3]
print a
class longList(shortList):
def __init__(self):
shortList.setList()
self.setList()
def setList(self):
a.extend([4,5,6])
print a
def main():
a = raw_input('Do you want short or long list? (s/l)')
if a.upper() == 'S':
lst = shortList()
else:
lst = longList()
lst.setList()
if __name__ == '__main__':
main()
After that I'm getting a message:
TypeError: unbound method setList() must be called with shortList
instance as first argument (got nothing instead)
Where is the problem?
Thanks in advance...
