Checking if a word is in a Scrabble hand in Python: Now, fill in check_word. It takes as arguments a word word and the scrabble hand letters; both are strings. It returns True if word can be constructed from the letters in letters and False otherwise. Note that the number of times a letter occurs matters: check_word('mississippi','ismp') should return False. It takes as its argument a string and returns a dictionary mapping letters to the number of times they occur in this string. Try starting out by applying letter_counts to both word and letters. Also, recall that you can iterate over the resulting dictionaries.
