Purpose of calling function without brackets python

Question

Consider the following:

class objectTest():

    def __init__(self, a):
        self.value = a

    def get_value(self):
        return self.value

class exec         


        

Answer 1

Functions and methods in Python are also objects themselves. Thus you can compare them just as you would any other object.

>>> type(a.get_value)

>>> type(a.get_value())

Normally of course you wouldn't compare methods to each other or anything else, because it's not terribly useful. One place it's useful is when you want to pass a function into another function.
