Looping through a list

Here are two ways to iterate over items in a list, similar to iterating over characters in a string.

This is the easiest way to iterate over all the items in a list, since you won't need the index of each item:

lst = [3, 5, 8, 9]

for num in lst:
    print(num)

Console results:

If you need to use the list index in the loop body, then you can iterate over the indices instead by using i as the index in the list:

lst = [3, 5, 8, 9]

for i in range(len(lst)):
    print(i, lst[i])

Console results:
