In python, write a function that takes a string argument that contains a sentence and returns a list of the words in that sentence that were written using at least one uppercase letter. You can assume that the sentence you received as an argument ends with either a ', a '!', or a '?', but has no other punctuation. As a clarifying example, if your function was called with the argument "This is the First question on your Second quiz." it must return the list ['This', 'First', 'Second']. You may use any of the ist or string processing functions you wish, and you may also use the ord, char, upper, and lower functions as well if you wish. 4.
