"""
#Example

#and the shopping list
shopping_list = [ spam , eggs , banana]
#result
2+5+4==11

can someone help me with this?

Answer 1

dict= {"bread" : 4 , "banana" : 4 , "spam" : 2, "eggs": 5, "range" : 6}
shopping_list = [ "spam" , "eggs" , "banana"]

sum=0
for a in dict.keys():
if a in shopping_list:
sum+= dict[a]
print(sum)

Answer 2

store_items= {"bread" : 4 , "banana" : 4 , "spam" : 2, "eggs": 5, "range" : 6}
shopping_list = [ "spam" , "eggs" , "banana"]
# list comprehension using dictionary .get() method and the sum function
# might help you too.

print(sum([store_items.get(item_required)for item_required in shopping_list]))
