[Python] Text based game: Get item [closed]

I am creating a text based game for my Python 140 class. One of the requirements is that the user can "get" an item from each room and add it to his inventory. When I run the code and attempt to "get" the item from that room, it errors with a traceback for line 56 saying "name 'lower' is not defined'". What am I doing incorrectly to cause the game not to add the item to inventory?

print("Welcome! To defeat HUNGER, you must collect all 6 SATIATING FOODS.")

name = input("What is your name? ")

rooms = {
'FOREST': {'North': 'PUB', 'East': 'FARM', 'West': 'FIELD'},
'PUB': {'North': 'HOUSE', 'East': 'CELLAR', 'South': 'FOREST', 'West': 'RESTAURANT', 'item': 'FISH AND CHIPS'
},
'FARM': {'North': 'FARMHOUSE', 'West': 'FIELD',
'item': 'POTATOES'
},
'FIELD': {'North': 'RESTAURANT', 'East': 'FOREST',
'item': 'BERRY MEDLEY'
},
'RESTAURANT': {'East': 'PUB', 'South': 'FIELD',
'item': 'STIR FRY'
},
'FARMHOUSE': {'North': 'CELLAR', 'South': 'FARM',
'item': 'HEARTY STEW'
},
'CELLAR': {'South': 'FARMHOUSE', 'West': "PUB",
'item': 'CANNED SOUP'
},
'HOUSE': {'South': "PUB",
'item': 'HUNGER'
},

}

directions = ['North', 'South', 'East', 'West']
location = 'FOREST'
item = ['POTATOES', 'BERRY MEDLEY', 'STIR FRY', 'FISH AND CHIPS', 'HEARTY STEW', 'CANNED SOUP']
inventory = []

print("Welcome to Trials of Harvest."
"You can go North, East, South, or West. Type 'Exit' to leave the game.")

while True: # Gameplay loop
print(f'You are in the {location}, {name}.')
print("Inventory:", inventory)
if rooms['item']:
print('Item in room: {}'.format(''.join(rooms['item'])))
print('------------------------------')

direction = input("Type North, East, South, West, or Exit: ").capitalize()

if direction in rooms[location]: # Check if the direction exists in the current room
location = rooms[location][direction] # Move to the new room
elif direction == "Exit":
print(f'Thanks for playing, {name}!')
break
elif lower().split()[0] == 'get':
item = " ".join(command.lower().split()[1:])
if item in rooms['item']:
Inventory.append(item)
print('You grabbed {}.'.format(rooms['item']))
else:
print("I don't see that here.")
else:
print('You cannot go that way!')

while currentRoom in ['HUNGER']:
if len(Inventory) == 6:
print('You collected all of the items, and defeated HUNGER!')
else:
print('It looks like you have not found everything, you lose!')
break
