Looping with Index using enumerate()

Snippet

When you need both the position (index) and the value of items in a list during a loop, enumerate() is the most efficient and readable way to do it.

snippet.py
python
items = ['apple', 'banana']
for index, val in enumerate(items):
    print(index, val)

Breakdown

items = ['apple', 'banana']

Define a list containing two string elements.

for index, val in enumerate(items):

Loop through the list, assigning the count to 'index' and the item to 'val'.

print(index, val)

Print both the current index and the item value together.
