    You can use simple unpacking for the item name like this:

    from collections import OrderedDict
od = OrderedDict()
for i in range(int(input())):
  *item, price = input().split()
  item = ' '.join(item)
  od.setdefault(item, 0)
  od[item] = od[item] + int(price)
for k,v in od.items():
  print(k + ' ' + str(v))
