In python, you can use the enumerate function to add a counter to
your objects in a tuple or list.
'''

myAlphabet = ['a', 'b', 'c', 'd', 'e']
countedAlphabet = list(enumerate(myAlphabet)) # List turns enumerate object to list
print(countedAlphabet) # [(0, 'a'), (1, 'b'), (2, 'c'), (3, 'd'), (4, 'e')]

myList = ['cats', 'dogs', 'fish', 'birds', 'snakes']

for index, pet in enumerate(myList):
  print(index)
  print(pet)

for i in range(len(values)):
    print(i, values[i])

# For loop with enumerate

# Results previous for loops:

# 1, b
# 2, c
# 3, d

# For loop with enumerate returning index and value as a tuple

¿Qué hace Enumerate en Python?

The enumerate() function assigns an index to each item in an 
iterable object that can be used to reference the item later. 
What does enumerate do in Python? It makes it easier to keep 
track of the content of an iterable object.
