Python enumerate()

The enumerate() method adds counter to an iterable and returns it (the enumerate object).

The syntax of enumerate() is:

enumerate(iterable, start=0)

enumerate() Parameters

enumerate() method takes two parameters:

  • iterable - a sequence, an iterator, or objects that supports iteration
  • start (optional) - enumerate() starts counting from this number. If start is omitted, 0 is taken as start.

Return Value from enumerate()

enumerate() method adds counter to an iterable and returns it. The returned object is a enumerate object.

You can convert enumerate objects to list and tuple using list() and tuple() method respectively.

Example 1: How enumerate() works in Python?

grocery = ['bread', 'milk', 'butter']
enumerateGrocery = enumerate(grocery)


# converting to list

# changing the default counter
enumerateGrocery = enumerate(grocery, 10)


<class 'enumerate'>
[(0, 'bread'), (1, 'milk'), (2, 'butter')]
[(10, 'bread'), (11, 'milk'), (12, 'butter')]

Example 2: Looping Over an Enumerate object

grocery = ['bread', 'milk', 'butter']

for item in enumerate(grocery):

for count, item in enumerate(grocery):
  print(count, item)

# changing default start value
for count, item in enumerate(grocery, 100):
  print(count, item)


(0, 'bread')
(1, 'milk')
(2, 'butter')

0 bread
1 milk
2 butter

100 bread
101 milk
102 butter
