Iterate into a multidimensional tuple with for loop

Question

I'm a beginner in Python and I'm trying to understand how the iterations in for loop work.

I have created a multidimensional tuple that contains integer like below

image_dimension = ((820, 312),
               (1500, 500),
               (2480, 520))

Now, I would like to use the index of every row of the tuple as an index in a for cycle.

I have tried the code for i in image_dimension: but clearly, it returns the tuple of every row and not the index

At the moment I'm using the following code to access the positions of the tuple

cycles = range(0, 3)
for count in cycles:
    aspect_ratio_x = image_width / image_dimension[count][0]
    to_crop_from_high_and_low = image_dimension[count][1] * aspect_ratio_x

      # do other stuff

but instead of using the range() function and manually change the element inside it, I would like the for loop automatically iterate the row of the tuple.

I know I could use something like cycles = range(0, len(image_dimension)) but I would like to make it cleaner

As suggested by @alani the solution is to use the enumerate() function

for index, (i, j) in enumerate(image_dimension):
    aspect_ratio_x = image_width / image_dimension[index][0]
    to_crop_from_high_and_low = image_dimension[index][1] * aspect_ratio_x
