I would appreciate advice on how to set up delgation in Python.
I am continuously implementing a function to test whether a Python
Fraction is an integer so I wanted to define a new class, based on
Fraction, that includes this new method.
But I am not clear on how to delegate from my new class to the existing
Fraction class. This is what I have:
--------------------------
class RF(Fraction):
def __new__(self, x, y):
super().__new__(self, x, y)
def is_integer(self):
return self.numerator % self.denominator == 0
def __getattr__(self, attr):
return getattr(self, attr)
--------------------------
which doesn't work.
Any advice on how to do this would be much appreciated.
