# Ghost Gobble Arcade Game Welcome to Ghost Gobble Arcade Game on Exercism's Python Track. If you need help running the tests or submitting your code, check out `HELP.md`. If you get stuck on the exercise, check out `HINTS.md`, but try and solve it without using those first :) ## Introduction Python represents true and false values with the [`bool`][bools] type, which is a subtype of `int`. There are only two values in this type: `True` and `False`. These values can be bound to a variable: ```python >>> true_variable = True >>> false_variable = False ``` We can evaluate Boolean expressions using the `and`, `or`, and `not` operators: ```python >>> true_variable = True and True >>> false_variable = True and False >>> true_variable = False or True >>> false_variable = False or False >>> true_variable = not False >>> false_variable = not True ``` [bools]: https://docs.python.org/3/library/stdtypes.html#typebool ## Instructions In this exercise, you need to implement some rules from [Pac-Man][Pac-Man], the classic 1980s-era arcade-game. You have four rules to implement, all related to the game states. > _Do not worry about how the arguments are derived, just focus on combining the arguments to return the intended result._ ## 1. Define if Pac-Man eats a ghost Define the `eat_ghost()` function that takes two parameters (_if Pac-Man has a power pellet active_ and _if Pac-Man is touching a ghost_) and returns a Boolean value if Pac-Man is able to eat a ghost. The function should return `True` only if Pac-Man has a power pellet active and is touching a ghost. ```python >>> eat_ghost(False, True) ... False ``` ## 2. Define if Pac-Man scores Define the `score()` function that takes two parameters (_if Pac-Man is touching a power pellet_ and _if Pac-Man is touching a dot_) and returns a Boolean value if Pac-Man scored. The function should return `True` if Pac-Man is touching a power pellet or a dot. ```python >>> score(True, True) ... True ``` ## 3. Define if Pac-Man loses Define the `lose()` function that takes two parameters (_if Pac-Man has a power pellet active_ and _if Pac-Man is touching a ghost_) and returns a Boolean value if Pac-Man loses. The function should return `True` if Pac-Man is touching a ghost and does not have a power pellet active. ```python >>> lose(False, True) ... True ``` ## 4. Define if Pac-Man wins Define the `win()` function that takes three parameters (_if Pac-Man has eaten all of the dots_, _if Pac-Man has a power pellet active_, and _if Pac-Man is touching a ghost_) and returns a Boolean value if Pac-Man wins. The function should return `True` if Pac-Man has eaten all of the dots and has not lost based on the parameters defined in part 3. ```python >>> win(False, True, False) ... False ``` [Pac-Man]: https://en.wikipedia.org/wiki/Pac-Man ## Source ### Created by - @neenjaw ### Contributed to by - @cmccandless - @BethanyG
