The operator Module in Python: itemgetter, attrgetter, methodcaller
In Python, the operator module provides functions for the built-in operators and functions to create callable objects that fetch items, attributes, and call methods. operator.itemgetter(), operator.attrgetter(), and operator.methodcaller() are often used for the key argument in functions like sorted(). See the following article for details.

Operator and Function Overloading in Custom Python Classes
Every class in Python defines its own behavior for built-in functions and methods. When you pass an instance of some class to a built-in function or use an operator on the instance, it is actually equivalent to calling a special method with relevant arguments.

Advanced Function Calling in Python - DEV Community
Python has a few interesting ways to call functions. This guide will show a few interesting ways to do so that's outside of a standard function call. These techniques can be used for more advanced cases, especially dynamic calling. Partials are essentially templates for how a function is called.
