Python: multiplication override
Just add the following to the class definition and you should be good to go:
__rmul__ = __mul__
Implement __rmul__ as well.
class Foo(object): def __mul__(self, other): print '__mul__' return other def __rmul__(self, other): print '__rmul__' return otherx = Foo()2 * x # __rmul__x * 2 # __mul__
