python return iteration number of for loop
# Basic syntax:
for iteration, item in enumerate(iteratable_object):
print(iteration)
# Where:
# - item is the current element in the iteratable_object
# - iteration is the iteration number/count for the current iteration
# Basic syntax using list comprehension:
[iteration for iteration, item in enumerate(iteratable_object)]
# Example usage:
your_list = ["a", "b", "c", "d"]
for iteration,item in enumerate(your_list):
(iteration, item) # Return tuples of iteration, item
--> (0, 'a')
(1, 'b')
(2, 'c')
(3, 'd')
[iteration for iteration, item in enumerate(your_list)]
--> [0, 1, 2, 3]
