python how to get index in for loop code example

Example 1: python3 iterate through indexes

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

Example 2: python for with iterator index

for index, value in enumerate(iterator):
    print(index, value)

Example 3: how to loop the length of an array pytoh

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

Example 4: python how to get index 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.

Example 5: python enumerate for loop

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

Example 6: for loop with index python

presidents = ["Washington", "Adams", "Jefferson", "Madison", "Monroe", "Adams", "Jackson"]
for i in range(len(presidents)):
    print("President {}: {}".format(i + 1, presidents[i]))
