python operator overload and friends

By : Bob

I wanted to know if anyone could give me an example of how to overload an operator within a class, in my case the + operator. Could I define a function (not a class method) that does it? I'm a newbie so I don't really know how to do it.

class MyNum(object):
    def __init__(self, val):
        self.val = val

    def __add__(self, num):
        return self.__class__.(self.val   num)

    def __str__(self):
        return self.__class__.__name__   '('   str(self.val)   ')'

print(MyNum(3)   2)   # -

When in doubt of the basics: manual.

Define its __add__() method.
