Sometimes, we want to access the index in Python for loops.

In this article, we’ll look at how to access the index in Python for loops.

How to access the index in Python for loops?

To access the index in Python for loops, we can use the enumerate function.

For instance, we write:

ints = [100, 200, 300]
for idx, val in enumerate(ints):
    print(idx, val)

to call enumerate with the ints array to return an array with the idx and val tuples.

idx is the index of the array entry.

val is the value of the array entry.

Therefore, we see:

0 100
1 200
2 300

logged as a result.

Conclusion

To access the index in Python for loops, we can use the enumerate function.
