For calculating dynamic number of shops input you can use itertools with zip_longest method. Hence you don't need to worry if the items length are not same.

import itertools
shop_items = itertools.zip_longest(shop1, shop2)
total = sum([sum(item["price"] for item in items if item)  for items in shop_items])
