python return iteration number of for loop

1# Basic syntax:
2for iteration, item in enumerate(iteratable_object):
3	print(iteration)
4# Where:
5#	- item is the current element in the iteratable_object
6#	- iteration is the iteration number/count for the current iteration
7
8# Basic syntax using list comprehension:
9[iteration for iteration, item in enumerate(iteratable_object)]
10
11# Example usage:
12your_list = ["a", "b", "c", "d"]
13
14for iteration,item in enumerate(your_list):
15	(iteration, item) # Return tuples of iteration, item
16--> (0, 'a')
17	(1, 'b')
18	(2, 'c')
19	(3, 'd')

21[iteration for iteration, item in enumerate(your_list)]
22--> [0, 1, 2, 3]
