We already know how to loop through lists in Python, let's see how to loop through strings in Python. The algorithm of this looping is exactly the same.

String example:

f = 'kiwi'

We counted number of letters in this string, number of letters 'i' and demonstrated the index number of each letter of this string in Python.

Also we know when to replace the iteration variable by the underscore and how to apply len function to strings and to lists.

We created a new variable and named it LETTER_TO_CHECK in order to avoid a difficult situation with the letter 'i'.
