In this third Scrabble exercise, you will write scrabble_all_plays(row, rack) to return a list of (k, word) pairs that represent all the possible plays that can be made anywhere on the row, given a dictionary of possible words. Use 'sorted' to sort the result. Instead of using the full official Scrabble dictionary, use the following (very) abridged list of words: dictionary = "HE HELL HELLO LOW OTHER HER THE THERE WELL ELL EL TEE TOE OX OXEN ZOO ZOOLOGY".split()
