Python: what is wrong with this function?

Question

this code is supposed to count the total of listed items price after it checks if the items are available on the stock (stock variable), I want to know why I doesn't print anything.

 shopping_list = ["banana", "orange", "apple"]
stock = {
 "banana": 6,
 "apple": 0,
 "orange": 32,
 "pear": 15
}
prices = {
 "banana": 4,
 "apple": 2,
 "orange": 1.5,
 "pear": 3
}
def compute_bill(food):
 total=0
 for i in food:
 if stock[i]>0:
 total+=prices[i]
 return total 
 print total
compute_bill(shopping_list)

Answer 1

Your print needs to be before the return statement:

def compute_bill(food):
 total=0
 for i in food:
 if stock[i]>0:
 total+=prices[i] 
 print total
 return total

• Abdnormal Abdou: another question, shouldn't it prints (4+1.5+3 )= 8.5 instead of 5.5?

Answer 2

If running in an IDE you will need to use print

print compute_bill(shopping_list)

The print total is unreachable after the return statement.

So either forget about the print or put the print before the return

• Abdnormal Abdou: another question, shouldn't it prints (4+1.5+3 )= 8.5 instead of 5.5?
• Padraic Cunningham: No, there is no apples in stock so if stock[i]>0: will be False for apples and the price won't be added so 5.5 is correct
• Abdnormal Abdou: I know that there is no apple in the stock that's why I said it should be 8.5, if the apple was in stock it would've been 10.5 !
• Abdnormal Abdou: why didn't you add "pear"? it is available in the stock!
• Padraic Cunningham: where do you see pear in the shopping list?
