enumerate can be used to get the index number of an element. For example.

#!/usr/bin/python3

fruits = ["apple", "banana", "orange", "grapes"]

for index, item in enumerate(fruits):
  print(f"index {index} = {item}")

Should return the following.

index 0 = apple
index 1 = banana
index 2 = orange
index 3 = grapes
