This is an error; frob() needs self declared. Same error below.
> class Bar(Foo):
> def frob():
> print "Eggs"
> # In C#, the syntax to call Foo's frob() would be

Coded like this:
class Foo:
def frob(self):
print "Spam"
class Bar(Foo):
def frob(self):
print "Eggs"
Foo.frob(self)
>> a = Bar()
>> a.frob()
Eggs
Spam
works just fine.
Note that you *must* pass self if you call a class method
directly.
