if p.weapon == items[sitem[1]]:
KeyError: 'o'

any help would be appreciated

Your "items" dictionary doesn't have a key named "o" which apparently you are trying to locate. The line if p.weapon == items[sitem[1]] is basically equating to if p.weapon == items["o"] . That seems to not be in the chunk of "relevant code" that you posted, but even so, the code you posted throws an error on its own.

Regarding the code, you shouldn't cycle the dictionary "items" like you are currently doing. Cycle the list of the values in the dictionary, and unpack them to variable names like this:

items = {'sword':['sword', 3, 15],
    'axe':['axe', 5, 25],
    'bow and arrow':['bow and arrow', 4, 20]}
for item, price, damage in items.values():
    print item
    print "\tprice", price
    print "\tdamage", damage

Your items dictionary is a little repetitive though, by putting the item name as both the key and the first index in the value of it. This is much better:

items = {'sword':[3, 15],
    'axe':[5, 25],
    'bow and arrow':[4, 20]}
# cycle through the (key, value) list of the dict
for item, stats in items.items():
    print item
    print "\tprice", stats[0]
    print "\tdamage", stats[1]

Hope that helped!

You can do this two different ways.

items = {'sword':['sword', 3, 15],
             'axe':['axe', 5, 25],
             'bow and arrow':['bow and arrow', 4, 20]}

##---- the easiest to understand
for key in items:
   print "key =", key
   weapon_list = items[key]
   print "\tweapon_list =", weapon_list
   print "\tprice =", weapon_list[1]
   print "\tdamage =", weapon_list[2]
   
##--- the way you tried to do it
for key in items:
   print items[key][0]
   print '\tprice:', items[key][1]
   print '\tdamage:', items[key][2]
