Make User Input Match Specific Criteria (Python)

I am currently working on a text based game for a school project. My only issue is that I cannot get my program to print 'Invalid input' when the user input does not include 'Take' and [item name]. So the item is added to inventory as long as the user input is 'Take'.

I tried adding this to my code but it still just accepts 'Take' for user input.

elif ('Take'+item) not in user_input:
print('Invalid input\n')
`

This operates the way you expect. I've made several changes in the organization here. I have removed all of your "automatic capitalization", so you must type the command exactly. I have removed all of your recursive calls and replaced them with loops -- this is not a proper use of recursion.
I also deleted your block title because I didn't want to deal with the character set. You can add that back in.

To validate Take + Items, you need to read input and store them somthing like below if i understand correctly .
# Check for Take in input and Item name
elif 'Take' in user_input:
item = user_input[5:]
if item in rooms[current_room].values():
inventory.append(item)
print('You have added {} to your inventory.'.format(item))

print('You can\'t take that!')

How can I add items and avoid duplicates to my inventory in a text based adventure game?

So I am trying to design a text based adventure game for one of my classes. I have the movement from room to room down, but have been struggling when it comes to getting items added to the inventory for the escape. At first when I tried to enter "get 'item'" I was prompted with 'invalid move' which was happening because there was an issue with the sequence I was calling my functions. Now that I have everything fixed, the items are automatically being added to the inventory without the user entering the get item function, and every time you enter a room, the item is being added despite it already being in the inventory. Here is my code:
def show_instructions():
print('Escape From Work Text Based Game')
print('Movement commands: South, North, East, West')
print("To pick up an item, type 'get [item]'")
print()
print('Your boss is asking you to come in on your days off. To escape without being seen, you will need to get your'
' vest, backpack, lunchbox, paycheck, name badge, and car keys.')
print('Do not enter the room that has your boss, or you can kiss your days off goodbye!')
def player_stat(current_room, inventory):
print('----------------------')
print('You are in the {}'.format(current_room))
print('Item in this room: {}'.format(rooms[current_room]['Item']))
print('Inventory: ', inventory)
print('----------------------')
def move(direction, current_room, rooms):
if direction in rooms[current_room]:
current_room = rooms[current_room][direction]
else:
print('You run into the wall, customers are staring. Try again.')
return current_room
rooms = {
'Garden Center': {'South': 'Hardware Dept.', 'West': 'Customer Service', 'North': 'HR Office',
'East': 'Storage Room', 'Item': 'None'},
'Customer Service': {'East': 'Garden Center', 'Item': 'lunchbox'},
'Hardware Dept.': {'East': 'Break Room', 'North': 'Garden Center', 'Item': 'backpack'},
'HR Office': {'East': 'Lounge', 'South': 'Garden Center', 'Item': 'paycheck'},
'Lounge': {'West': 'HR Office', 'Item': 'name badge'},
'Break Room': {'West': 'Hardware Dept.'},
'Storage Room': {'West': 'Garden Center', 'North': 'Admin Office', 'Item': 'vest'},
'Admin Office': {'South': 'Storage Room', 'Item': 'keys'}
}
directions = ['North', 'East', 'South', 'West']
current_room = 'Garden Center'
inventory = []
show_instructions()
while current_room != 'Exit':
player_stat(current_room, inventory)
player_move = input('What is your command?: ').lower().title()
if player_move == 'exit':
current_room = 'Exit'
print('Sorry to see you go, play again soon!')
elif player_move in directions:
current_room = move(player_move, current_room, rooms)
item = rooms[current_room].get('Item')
if item is not None and player_move == 'get ' + item:
if item in inventory:
print('You already have this item in your inventory!')
else:
inventory.append(item)
if current_room == 'Break Room':
print('Oh no! You got caught. Have fun working this weekend.')
exit()
else:
print('Invalid move')
And this is what the output looks like after I have moved from a few of the rooms. I don't understand why it is printing invalid move after every move even if it is valid either.
You are in the HR Office
Item in this room: paycheck
Inventory: ['paycheck', 'paycheck']
----------------------
Where would you like to go?: south
Invalid move
----------------------
You are in the Garden Center
Item in this room: None
Inventory: ['paycheck', 'paycheck', 'None']
----------------------
Where would you like to go?: south
Invalid move
----------------------
You are in the Hardware Dept.
Item in this room: backpack
Inventory: ['paycheck', 'paycheck', 'None', 'backpack']
----------------------
I also still have to add a way to exit the game when you win after collecting all 6 items, and i was heading in the direction of 'if inventory == [ all 6 items in list ]: print( you win) followed by exit' Any help anyone has to offer would be greatly appreciated.

Try
#Loop continues if user has not entered 'exit' or inventory is not up to 6 items
while current_room != 'Exit' and len(inventory)!= 6:
player_stat(current_room, inventory)
player_move = input('What is your command?: ').lower().title()
if player_move == 'Exit':
current_room = 'Exit'
print('Sorry to see you go, play again soon!')
exit()
elif player_move in directions:
current_room = move(player_move, current_room, rooms)
item = rooms[current_room].get('Item')
#As the input has .title() this condition will accept input of item in that format
if item is not None and player_move == 'Get ' + item.title():
if item in inventory:
print('You already have this item in your inventory!')
#Was adding repeat items because of prior incorrect indentation
#Correct indentation with the else applying after checking inventory
else:
inventory.append(item)
if current_room == 'Break Room':
print('Oh no! You got caught. Have fun working this weekend.')
exit()
#Replaced the 'else' statement with this so the console doesn't return 'Invalid move' every time
if "get " + item not in player_move and player_move not in directions:
print('Invalid move')
#When loop breaks, user will have won
print("You won!")

Your indentation is wrong. You have this:
if item is not None and player_move == 'get ' + item:
if item in inventory:
print('You already have this item in your inventory!')
else:
inventory.append(item)
but I think you want this:
if item is not None and player_move == 'get ' + item:
if item in inventory:
print('You already have this item in your inventory!')
else:
inventory.append(item)

Building a Text Based Game in Python, area not defined

I'm working on a text based game in python and everything seems to be working except for the area which the player will travel to and collect items in. When I start the game, it goes through the intro (which I left out) and then shows me this error along with the player's stats:
item = player(location)
enter code hereline 59, in player
return area[location]['item']
NameError: name 'area' is not defined
I don't really understand how to fix it, I've been trying to define area but I'm still getting the same error.

print(' \n Using the commands, North, South, East and West to navigate through the warehouse.')
print('Find your Tiramisu cake! Search the rooms of the warehouse to get your cake!')

else:

else:

You haven't passed area to the fecth() and stats() functions.
Either pass it or make it global

Moving Between Rooms

The code I have is as follows:

This is a small part of a larger text based game that I am supposed to develop as part of my college class. The goal of this program is to get user input to move between rooms. I used the template dictionary given and am trying to restrict inputs to the instruction list with the exception of the word 'exit'. So the major issue I am having is how to use the return function properly in the function I created to yield the correct result.
It is giving me a 'KeyError' of 'South' in the console everytime I try to input go south as the first direction. Any help would be appreciated.

Well, to answer your main question of why you are seeing that KeyError, is because you are trying to access a key that doesn't exist for the nested dictionary value of 'Bedroom'. Look at the k-v pair you made for that key.
You would have to do this instead to return the value for 'South' key:
if direction == 'go south':
room = 'Greathall'
return rooms[room]['South']
>>> 'Bedroom'
Just a tip here: why not call the room directly in the dictionary value extraction so instead of defining room as 'Greathall', you could do:
return rooms['Greathall']['South']
Which will give you the same response.

Invalid move condition, Python text based game

I need help with a text-based python game, I have done most of the work, I can move between all 3 rooms, there is 'Great hall' at the top then go south 'Bedroom' go east 'Cellar' the I can go back so go west 'bedroom' go north finally to get back to the great hall.
the problem is if I'm in the great hall and type east it skips to cellar instead of saying invalid move there's a wall.
what I'm trying to do
Output that displays the room the player is currently in.
Decision branching that tells the game how to handle the different commands. The commands can be to either move between rooms (such as go North, South, East, or West) or exit.
If the player enters a valid “move” command, the game should use the dictionary to move them into the new room.
If the player enters “exit,” the game should set their room to a room called “exit.”
If the player enters an invalid command, the game should output an error message to the player (input validation).
A way to end the gameplay loop once the player is in the “exit” room
this is the code I have written so far
rooms = {
'Great Hall': {'South': 'Bedroom'},
'Bedroom': {'North': 'Great Hall', 'East': 'Cellar'},
'Cellar': {'West': 'Bedroom'}
}
def player_stat():

player_stat()
player_move = input('Enter your move:\n')
if player_move in ['Exit', 'exit']:
currentRoom = 'Exit'

print('YOU MADE IT TO THE CELLAR, try to go back to the Great Hall')
elif player_move in ['West', "west"]:
currentRoom = 'Bedroom'
