Question

How can I overload class methods?
I failed with:

class D(object):
    def create(self):
        foo = 100
        bar = 'squirrels'
        baz = 'I have %d insane %s in my head.' % (foo, bar)
        return baz     

class C(D):
    def create(self):
        super(C, self).create()
        baz = 'I have %s cute %s in my yard.' % (self.foo, self.bar)

C().create()

Traceback was:

AttributeError: 'C' object has no attribute 'foo'

Answer 1

You have tried to use local variables as class attributes. Try to do the following changes:

class D(object):
    def create(self):
        self.foo = 100
        self.bar = 'squirrels'
        baz = 'I have %d insane %s in my head.' % (self.foo, self.bar)
        return baz

class C(D):
    def create(self):
        super(C, self).create()
        print self.foo
        self.baz = 'I have %s cute %s in my yard.' % (self.foo, self.bar)

C().create()
