Dictionary value is not changed inside a for loop assignment

Question

So I am learning python using Learn python the hard way. I am trying to develop a inventory system. The goal is to build this into a class that will be pulled by the room

Answer 1

zbs is correct, you're only changing the value of the pointer to the dict value. However, you're making this way too hard:

#This is the inventory in this room
inventory = {'Miniature Fusion Warhead': 'desk',
             'knife':'bed'}
player_inventory = set()

def take(item):
  if item in inventory:
    print("You picked up the {}".format(item))
    player_inventory.add(item)
    del inventory[item]

  else:
    print("That item doesn't exist")

while True:
  print('')
  print("Inventory: " + ', '.join(player_inventory))
  for k,v in inventory.items():
    print("You see a {} on the {}".format(k, v))

  print("What do you want to pick up?")
  ui = raw_input("> ").split()
  verb = ui[0]
  item = ' '.join(ui[1:])
  if verb == 'take':
    if item:
      print("You take the {}".format(item))
      take(item)
    else:
      print("That item doesn't exist")
  else:
    print("That's not an action")
