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
