Often, when dealing with iterators, we also get need to keep a count of iterations. Python eases the programmers’ task by providing a built-in function enumerate() for this task. Enumerate() method adds a counter to an iterable and returns it in a form of enumerating object. This enumerated object can then be used directly for loops or converted into a list of tuples using the list() function.


enumerate(iterable, start=0)


  • Iterable: any object that supports iteration
  • Start: the index value from which the counter is to be started, by default it is 0



# Python program to illustrate
# enumerate function
l1 = ["eat", "sleep", "repeat"]
s1 = "geek"
# creating enumerate objects
obj1 = enumerate(l1)
obj2 = enumerate(s1)
print ("Return type:", type(obj1))
print (list(enumerate(l1)))
# changing start index to 2 from 0
print (list(enumerate(s1, 2)))


Return type: 
[(0, 'eat'), (1, 'sleep'), (2, 'repeat')]
[(2, 'g'), (3, 'e'), (4, 'e'), (5, 'k')]

Using Enumerate object in loops:


# Python program to illustrate
# enumerate function in loops
l1 = ["eat", "sleep", "repeat"]
# printing the tuples in object directly
for ele in enumerate(l1):
    print (ele)
# changing index and printing separately
for count, ele in enumerate(l1, 100):
    print (count, ele)
# getting desired output from tuple
for count, ele in enumerate(l1):


(0, 'eat')
(1, 'sleep')
(2, 'repeat')
100 eat
101 sleep
102 repeat
