Learn how to simplify your loops with Python’s enumerate (). This tutorial shows you how to pair items with their index cleanly and effectively using real-world examples. enumerate () function adds a counter to each item in a list or any other iterable, and returns a list of tuples containing the index position and the element for each element of the iterable. The enumerate () function in Python is a simple yet powerful way to simplify looping with counters. It is a built-in function in Python that helps to create an iterator that returns pairs of elements and their index, which can be useful for various programming tasks. Learn how to use enumerate() to access each item in an iterable with a count value that specifies the order. See different ways to invoke enumerate() with built-in and custom iterables, and how to convert the output to lists, tuples or dictionaries.
