How to split a string into a list?
This should be enough to store each word in a list.
words is already a list of the words from the sentence, so there is no need for the loop.

If sep is not specified or is None, a different splitting algorithm is applied: runs of consecutive whitespace are regarded as a single separator, and the result will contain no empty strings at the start or end if the string has leading or trailing whitespace.
