Python Text-based adventure game with inventory posing "nonetype" issues.

I'm trying to design a game for a project that uses different 'rooms' and an inventory to navigate a player through to the end, and if the player does not have all the items in the inventory then it's game over.

I need help to correct a NoneType error that I believe will come up multiple times if it is coming up in the start.

This is what I have so far:

rooms = { 'Large Clearing': {'South': 'Deer Stand', 'North': 'Hunter Shack 1', 'West': 'Rabbit Den', 'East': 'Woods'}, 'Woods': {'East': 'Large Clearing', 'South': 'Hunter Shack 2'}, 'Hunter Shack 1': {'South': 'Large Clearing'}, 'Hunter Shack 2': {'North': 'Woods', 'South': 'Cliff'}, 'Hunter Shack 3': {'East': 'Rabbit Den'}, 'Rabbit Den': {'East': 'Large Clearing', 'West': 'Hunter Shack 3'}, 'Deer Stand': {'North': 'Large Clearing', 'East': 'Cliff'}, 'Cliff': {'North': 'Hunter Shack 2', 'West': 'Deer Stand'} } def large_clearing_mid(): print("This is where you woke up. There's nothing of importance here, you should keep moving.") move = input()

 def hunter_shack1(): global inventory if 'Axe' not in inventory: print("You see a hunter's shack. There are no footprints in the snow. It does not appear to have had " "visitors") print("in quite some time. You enter. There is a topographic map of the area on the far wall. On it " "are some X's.") print("One is labeled 'HERE', and the other two have names next to them. 'Henry' and 'Wayne'. " "Henry's X is to") print("the South West, and Wayne's X is to the South East. These must be other hunter's shacks marked.") print("You wonder if these men were friendly with each other. You continue to look around.") print("There are some pelts, a couple of decks of cards, binoculars, and an axe above the door.") print("The cards and binoculars don't look very useful. You'll leave them here for the hunter.") print("What do you do?") move = input() if move in ['take axe', 'pick up axe']: print("You take the axe. It looks sturdy and sharp. This can be useful.") inventory = inventory.append('Axe') print("That looks like everything useful. What now?") move = input() elif move not in ['take axe', 'pick up axe']: print("Invalid move. Try again.") move = input() else: print('Invalid move.') move = input() while 'Axe' in inventory: print("This is where you got the axe. The map said there were two shacks in the South East and South " "West.") print("The shack did not offer anything else of use. You should find the other shacks.") print("Where to now?") move = input()

def deer_stand(): global inventory print("A deer stand blends in with the surrounding forest. You understand why the deer are fooled by such a " "construct. Seeing no rifle barrels poking through the gaps or flaps of the stand, you assume it's safe" "to look around. Inside the stand, a single flare gun sits. The hunters must keep this here in case of " "dangerous animals or in the chance that they get injured themselves." "What do you do?") move = input() if move in ['pick up flare gun', 'take flare gun']: print("You pick up the flare gun.") inventory = inventory.append('Flare Gun') move = input() elif move in ['shoot flare gun', 'shoot gun', 'shoot flare']: print("You don't think it would be a good idea to shoot that just yet. You don't know if anybody is near " "enough to see it if you did.") move = input()

while current_room != 'q': while current_room == 'Large Clearing': if move in ['North', 'go North']: current_room = 'Hunter Shack 1' hunter_shack1() elif move in ['South', 'go South']: current_room = 'Deer Stand' elif move in ['West', 'go West']: current_room = 'Rabbit Den' #Fix Me Rabbit Den elif move in ['East', 'go East']: current_room = 'Woods' #Fix Me Woods elif move in ['Q', 'q']: current_room = 'q' else: print("Invalid move.") move = input()

 while current_room == 'Hunter Shack 1': if move in ['South', 'go South']: current_room = 'Large Clearing' large_clearing_mid() elif move in ['East', 'go East', 'West', 'go West', 'South', 'go South', 'North', 'go North']: print("You don't think that way will led you anywhere. How about somewhere else?") move = input() elif move in ['Q', 'q']: current_room = 'q' else: print("Invalid move.") move = input() while current_room == 'Deer Stand': deer_stand()

I cannot get the program to move to another room and run its defined code once the player gets the axe. It produces this error every time:

TypeError: argument of type 'NoneType' is not iterable in reference to 'while 'Axe' in inventory:'

Similarly, I cannot get the main gameplay to operate without the defined "hunter_shack1()" to be in the while current_room = 'Large Clearing' function. I cannot get it to process as it's own when current_room = 'Hunter Shack 1'

Help is greatly appreciated!
