Enumerate() in a for Loop
The enumerate()
function proves valuable when we need to access both the value and its index within any sequence, such as a list or string.
For instance, a list serves as an ordered data structure that associates each item with a unique index number. Utilizing this index number, we can conveniently access or alter the corresponding value.
The syntax for using enumerate()
is: for index, value in enumerate(___)
Note
As a quick reminder: index refers to the position of an element. In Python, we begin counting indexes from 0.
Examine the following code:
numbers = [2, 3, 8, 5, 6, 7, 8, 11, 8] # Printing all elements of the list with their indexes for i, v in enumerate(numbers): print('Numbers[', i, '] =', v)
How does the code work?

Count the quantity of numbers in the list that are multiples of three.
- Configure the
for
loop withenumerate()
to operate onnumbers
, employingi
for indexes andv
for values. - Establish the condition that checks whether a number is a multiple of three.
- Increment the
counter
by1
if the number meets the condition. - Display the value of the
counter
.
