Python Code Answer:

    total_score = 0.0
    min_elapsed = 0.010
    hand_score = 0.0

    time_limit = raw_input('Enter Time Limit: ')

    else:

        return

    while True:

        num_letters = 0
        for key in hand.keys():
            for i in range(hand[key]):
                num_letters += 1
                print key,

        if num_letters < 1:
            break

        start = time.time()
        word = raw_input('Word: ')
        stop = time.time()
        
        elapsed = stop - start
        time_limit -= elapsed

        # prevent divide by zero error, force min time
        if elapsed < min_elapsed:

        if word == '.':
            break

        if is_valid_word(word, hand, word_list):
            update_hand(hand, word)
            if time_limit > 0.0:
                hand_score = get_word_score(word, num_letters) / elapsed

        else:
            print "Invalid word. Try again."

        if time_limit >= 0:
