Answer 2

It will iterate through a list and it will make a tuple of each item with an index starting at zero by default
for example

lst = ['first', 'second', 'third']
print(list(enumerate(lst)))

The output will be list of tuples like this
[(0, 'first'), (1, 'second'), (2,'third')]

If you want to start insexing by one you can do it by a second argument like this

lst = ['first', 'second', 'third']
print(list(enumerate(lst, 1)))

This will give

[(1, 'first'), (2, 'second'), (3,'third')]
