Function Objects and Operator Overloading
From wikipedia: In Python, functions are first-class objects, just like strings, numbers, lists etc. This feature eliminates the need to write a function object in many cases. Any object with a call() method can be called using function-call syntax. An example is this accumulator class (based on Paul Graham's study on programming language syntax and clarity):
Can you write Python code for it?

#Here is the Python code you requested.

class Accumulator(object):
    def __init__(self, n):
        self.n = n

    def __call__(self, x):
        self.n += x
        return self.n

a = Accumulator(4)
print(a(3))
print(a(2))
