How to Count the Number of for Loop Iterations in Python

John on May 12, 2021

In this tutorial, we will learn how to count each iteration in a Python for loop for a final count or to use the current iteration number inside the loop.

To count iterations we can use the Python enumerate() function and pass it in as the first argument of the for loop.

items = ["a", "b", "c", "d"]

for iteration, item in enumerate(items):
 print(iteration)

0
1
2
3

Get Total Number of Iterations

If you only need the total iterations that were made, you can increment an integer by 1 on each iteration.

items = ["a", "b", "c", "d"]
cnt = 0

for item in items:
 cnt += 1

print(cnt)
