Hi!
Suppose I have a class A whose implementation I don't know about.
That class A has a method f that returns a A object.
class A:
...
def f(self, <...>):
...
Now I want to write B derived from A with method f1. I want f1 to return
a B object:
class B(A):
...
def f1(self, <...>):
...
res=f(<...>)
How do I return res as a B object?
Thanks.
