calling class methods as functions

[Giorgi Lekishvili]

Hello!

I wonder if someone explaines tom how can I overcome the following
problem in Python2.0 (I have to use this interpreter):
suppose, we have 2 classes, B, and C.

in class B we have a method "write"

in class C we have a method "write"

def write (self, arg):
    import B
    res=B.B.write(self, arg)    #res is a string being either "ok" or
"failure"
    del B
    return res


The interpreter gives an error, that class isntance must be given as 1st
argument.

What's wrong?

Thanx,
Giorgi

PS. I know that the best solution is to make a baseclass and put the
method "write" there. Of course. But I would like to know why this
solution fails.
