Since you look up the items in the grocery list it seems to me a
dictionary relating each item to its aisle would be best.
inventory = {"chips" : 1, "bread" : 1, "pretzels" : 1, "magazines" : 1,
"juice" : 2, "ice cream" : 2,
"asparagus" : 3}
MAX_AISLE = 3
aisles = [[] for i in range(MAX_AISLE)]
for item in grocery_list:
aisle = inventory.get(item.strip(), MAX_AISLE)
aisles[aisle-1].append(item)
To address the formatting question:
for aisleNo, items in enumerate(aisles):
if aisleNo < MAX_AISLE - 1:
print "Located on aisle %s" % aisleNo + 1
else:
print "Not in store"
print "\n".join(items)
