Python - 'call' a class

Question

If I have a class, is there anyway to catch the event of calling it as if it were a function?

obj = ExampleClass()
obj() -- and error occurs because I am 'calling' a class instance

I would like to handle this event inside the actual class definition.

Answer 1

You can define a __call__ method on your class.

class ExampleClass(object):
    def __call__(self):
        # do whatever you want here!
