python come ottenere l'indice in for loop

# There are two ways to do this
# The "beginner" one:
index = 0
foods = ["burger", "pizza", "apple", "donut", "coconut"]
for food in foods:
  print("Food", index, "is", food)
  index += 1

# Or using enumerate:
foods = ["burger", "pizza", "apple", "donut", "coconut"]
for index, value in enumerate(foods):
    print("Food", index, "is", value)

# By convention, you should understand and use the enumerate function as it makes the code look much cleaner.
