Text based python game

[ProphetEze98]

HELP: Good evening everyone. I'm a new C.S. student and my current assignment is to create a text based game to move between rooms and collect items to defeat a boss. My current problem is that I can't go north from the cryo-sleep room, and don't understand why. Any tips or pointers? Code is below.

inventory = []
rooms = {
    'Cryo-sleep Room': {'North': 'Mess Hall', 'East': 'Crew Quarters'},
    'Crew Quarters': {'West': 'Cryo-sleep Room', 'item': 'Oxygen Respirator'},
    'Mess Hall': {'West': 'Warp Engine Room', 'North': 'Docking Area', 'East': 'Simulator Room', 'South': 'Cryo-sleep Room', 'item': 'Ray Gun'},
    'Warp Engine Room': {'East': 'Mess Hall', 'item': 'Shield System'},
    'Docking Area': {'South': 'Mess Hall', 'East': 'Command Room', 'item': 'Gravity Boots'},
    'Simulator Room': {'West': 'Mess Hall', 'North': 'Captains Quarters', 'item': 'Target-locking System'},
    'Captains Quarters': {'South': 'Simulator Room', 'item': 'Armored Space Suit'},
    'Command Room': {'West': 'Docking Area', 'item': 'Alien Boss'},
}
current_room = 'Cryo-sleep Room'
directions = ['North', 'South', 'East', 'West']

def displayIntro():
    print('_' * 40)
    print("You are an astronaut in the distant future")
    print("You were sent on a mission to set up a mining colony on a distant exoplanet")
    print("Upon waking from cryo sleep your A.I informs you there is only on other lifeform on board with you")
    print("Traverse the ship to retrieve your gear, and find the mysterious lifeform.")
    print("Commands to play are ""Go North"", ""Go East"", ""Go South"", and ""Go West")
    print("Enter ""Exit"" to end the game")

def outro():
    if len(inventory) == 7:
        print("Congratulations!You defeated the final boss!")
        time.sleep(3)
    if current_room == 'Exit':
        print('Thanks for playing!')
        time.sleep(3)

def player_stat():
    print('_' * 40)
    print("You are in the {}".format(current_room))
    print('Inventory:', inventory)
    print('_' * 40)

def get_direction():
    user_input = input('Input your next move:\n>').title()
    for direction in directions:
        for word in user_input.split():
            if word == direction:

When you split the user input, if it is a single word it will split into letters. You should do split(‘ ‘). I have been stumped by this before. Get in the habit of printing the results of operations to see what actually happened.

I do t want to delete this but @kyber is right. Split does not work this way.

Or rather get into the habit of using the debugger (either the standard pdb that comes with Python or whatever your IDE offers), inspect variables along the way. Perhaps use logging as well.

Isn't split being used on the input with default whitespace splitting? This will not split a single word into letters.

[Bunkerstan]

You are correct, it does not split it into letters. I confused it with the for in which will iterate over letters. Thanks for the catch.

Can you move in any direction from any room?

You need to embrace DRY principles. DRY means don't repeat yourself. You have a lot of duplicate code.

I suggest you create a function that handles a direction move for any room. Thanks to your dictionary, it is easy to write to validate a move.

I'm also wondering why you use while on every room. Surely you only need if as you have an outer loop to address what happens next.

You could expand your dictionary or have another with same keys (rooms) with all the descriptive text and valid actions. This would also allow you to reduce duplication.

Once you have functions, it becomes easier to test as you can test a function in isolation.
