Why doesn't my list change?
<p>I've been hacking away on a little game, just for fun, and I've run into a problem. I'll post the code and try my best to explain:</p>

<pre><code>def parseCmd(string):
    cmd = string.split(' ')
    if cmd[0] == 'help':
        showHelp()
    elif cmd[0] == 'add':
        addServer()
    elif cmd[0] == 'bag':
        viewInventory(inventory)
    elif len(cmd) == 1 and cmd[0] == 'look':
        describeRoom()
    elif len(cmd) == 1 and cmd[0] == 'take':
        print 'What do you want me to take?'
    elif cmd[0] == 'take':
        pickUp(cmd[1],  items)
    elif cmd[0] == 'exit':
        sys.exit(0)
    else:
        print 'I don\'t know how to '  + cmd[0]

def describeRoom():
    print locations[player_location]

def pickUp(item,  item_list):
    if item in item_list[player_location]:
        item_list[player_location].remove(item)
        inventory.append(item)
        print 'You took the ' + item        
    else:
        print 'I can\'t find any ' + item

inventory = ['id card',  'money',  'keys']
player_location = 'cookieroom'
items = {'cookieroom': ['crowbar',  'hammer']}
locations = {'cookieroom': 'The cookieroom, where all the hard work gets done. \n\nNORTH: LFA - ITEMS: %s' % items[player_location], 
                'LFA': 'The infamous LFA, where dreams of office supplies become reality. there is a big guy sleeping in his chair next to a fire extinguisher.\n\nSOUTH: Cookieroom, WEST: WC'}

if __name__ == "__main__":
    while 1:
        t = raw_input('-&gt; ')
        parseCmd(t)
</code></pre>

<p>So, as you can see I want the list of items in the items dictionary to change when you pick up an item available in that specific room. I can pick up the item and it gets added to my inventory but if I issue the command 'look' it shows the list of items in it's original state.</p>

<p>I've been googling and stackoverflowing for 1½ day now and I can't find anything that seems to solve this problem.</p>

<p>If something is unclear, just ask me and I'll try to answer.</p>
