It's one of the methods of the built-in functools class of Python.Python also accepts function recursion, which means a defined function can call itself. Recursion is a common mathematical and programming concept. It means that a function calls itself. This has the benefit of meaning that you can loop through data to reach a result.

In Python, an array is used to store multiple values or elements of the same datatype in a single variable. The extend () function is simply used to attach an item from iterable to the end of the array. In simpler terms, this method is used to add an array of values to the end of a given or existing array.

Functions make code more modular, allowing you to use the same code over and over again. Python has a number of built-in functions that you may be familiar with, including: print () which will print an object to the terminal.Python closure is a nested function that allows us to access variables of the outer function even after the outer function is closed. Before we learn about closure, let's first revise the concept of nested functions in Python. Dictionaries and Sets. Python’s membership operators also work with dictionaries and sets. If you use the inor not inoperators directly on a dictionary, then it’ll check whether the dictionary has a given key or not.
