Watch Now This tutorial has a related video course created by the Real Python team. Watch it together with the written tutorial to deepen your understanding: Looping With Python enumerate()[1]
In Python, a for loop[2] is usually written as a loop over an iterable object. This means you don’t need a counting variable to access items in the iterable. Sometimes, though, you do want to have a variable that changes on each loop iteration. Rather than creating and incrementing a variable yourself, you can use Python’s enumerate() to get a counter and the value from the iterable at the same time!
In this tutorial, you’ll see how to:
Use enumerate() to get a counter in a loop Apply enumerate() to display item counts Use enumerate() with conditional statements Implement your own equivalent function to enumerate() Unpack values returned by enumerate()Let’s get started!
