Looping With Python enumerate() – Real Python

In Python, a for loop is usually written as a loop over an iterable object. This means that 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 course, you’ll see how to:

• Use enumerate() to get a counter in a loop
• Apply enumerate() to display item counts
• Implement your own equivalent function to enumerate()
• Unpack values returned by enumerate()
