Assignment 12

Problems

  1. Split into two groups and draw a UML class diagram for Hunt the Wumpus. One group will wirte the UML for the design given in in class and the other group will do a UML for an alternative design (Simon's implementation). You can do this by hand or using software (for example MS Visio or Gliffy), it's up to you. Once both groups have a UML diagram we will compare and discuss the advantages and disadvantages of each design.

  2. Add a docstring containing a sufficient set of doctest tests and a call to run those tests to the module below,

    # ScrabbleScoring.py
LETTER_VALUES = {'A':1, 'B':3, 'C':3, 'D':2, 'E':1, 'F':4, 'G':2,
         'H':4, 'I':1, 'J':8, 'K':5, 'L':1, 'M':3, 'N':1,
         'O':1, 'P':3, 'Q':10, 'R':1, 'S':1, 'T':1, 'U':1,
         'V':4, 'W':4, 'X':8, 'Y':4, 'Z':10}
def scrabble_value(s):
   'Returns the Scrabble score for the letters in the string s.'
    total_value = 0
    for letter in s:
        total_value = total_value + LETTER_VALUES[letter]
    return total_value

  3. Replace the code below that tests the function isStraight with an equivalent set of doctests. Fill in the body of isStraight and run the tests on it.

    # is_straight_doctest.py
def isStraight(hand):
    pass
if __name__ == '__main__':
    # TEST_HANDS is a list containing the hands of cards to use in testing
    # the function isStraight, and the correct result for each hand.
    # Note that not all hands have five cards, and some are straights,
    # while some are not.
    TEST_HANDS = [
        [[ 1, 2, 3, 4, 5 ], True],
        [[ 5, 4, 3, 2, 1 ], True],
        [[ 14, 0, 28, 42, 4 ], True],
        [[ 1, 2, 3, 4, 5, 6 ], True],
        [[ 5 ], True],
        [[ 1, 2, 2, 4, 5 ], False],
        [[ 1, 2, 2, 5, 5 ], False],
        [[ 1, 3, 5, 7, 9 ], False]
    ]
    print 'Testing isStraight ... '
    # Loop through the list of TEST_HANDS, to test each sample hand.
    for test in TEST_HANDS:
        # If the function isStraight does not return the correct
        # result...
        if isStraight(test[0]) != test[1]:
            # ... display an error message
            print 'isStraight fails on', test[0]
