Python 2.7 quick reference

You can define special methods that will handle calls to some of Python's built-in functions. The number of arguments will be the same as for the built-in functions, except that self is always the first argument.

For example, a special method to handle calls to function divmod(x, y) will look like this:

    def __divmod__(self, other):
        ...

In this method, the value of the first argument will be passed to self and the second argument to other.
