python how to get index in for loop

1items=['baseball','basketball','football']
2for index, item in enumerate(items):
3    print(index, item)

1array = range(10)
2for i in range(len(array)):
3  print(array[i])

1# There are two ways to do this
2# The "beginner" one:
3index = 0
4foods = ["burger", "pizza", "apple", "donut", "coconut"]
5for food in foods:
6  print("Food", index, "is", food)
7  index += 1
8
9# Or using enumerate:
10foods = ["burger", "pizza", "apple", "donut", "coconut"]
11for index, value in enumerate(foods):
12    print("Food", index, "is", value)
13
14# By convention, you should understand and use the enumerate function as it makes the code look much cleaner.

1presidents = ["Washington", "Adams", "Jefferson", "Madison", "Monroe", "Adams", "Jackson"]
2for num, name in enumerate(presidents, start=1):
3    print("President {}: {}".format(num, name))

2for i in range(len(presidents)):
