Python has a set of built-in methods and
__call__ is one of them. The
__call__ method enables Python programmers to write classes where the instances behave like functions and can be called like a function. When the instance is called as a function; if this method is defined,
x(arg1, arg2, ...) is a shorthand for
x.__call__(arg1, arg2, ...).
object() is shorthand for object.__call__()
