Python’s Enumerate Function


title: Python’s Enumerate Function

Overview

enumerate() is a built-in function in Python. It is useful for iteration over a list or any other iterable.

Arguments

enumerate() requires an iterable, and start as an optional parameter (it defines where the indexing starts).

Return Value

Returns an enumerate object. If you call list() on it, you can see that each item in the object is a tuple – an index followed by the item in the iterable.

Usage Example

animals = ['cat', 'dog', 'rabbit', 'fox', 'wolf'] # A list of animals. for index, item in enumerate(animals, start=20): print(index, item)

Output

20 cat 21 dog 22 rabbit 23 fox 24 wolf
