Python – enumerate()

Python enumerate() builtin function takes an iterable object, and returns an enumerate object.

Syntax

The syntax of enumerate() function is

enumerate(iterable, start=0)

where

iterable is a sequence
start is an optional integer value. Default value is 0. If any other value is passed, then the __next__() method of the iterator returned by enumerate() function returns a tuple containing the count and the value from iterable. count starts at the given start value for the first item in the iterable.

Example

Python Program

fruits = ['apple', 'banana', 'cherry']

for item in enumerate(fruits):
    print(item)

Run

Output

(0, 'apple')
(1, 'banana')
(2, 'cherry')
