“Ballpark orders” challenge troubles

Question

Hi all,
I’m trying to complete the Code Coach challenge “Ballpark Orders” using Python. I want the code to take an input string of several words (food orders), compare those to a dictionary, and add up the total price of each item that was ordered.
This results in 5, so I assume something is wrong with my if statement; I don’t think it is checking the words in the string in the way that I want it to.
Any help?

1 prices = {
2 "nachos": 6.0,
3 "pizza": 6.0,
4 "cheeseburger": 10.0,
5 "water": 4.0,
6 "coke": 5.0
7 }
8
9 order = input() #example: “water water coke pizza”
10 order = (x for x in order)
11
12 def place_order(dict, key):
13 total = 0
14 if key in dict:
15 total += dict.get(key)
16 return total
17 else:
18 total += 5.0
19 return total
20
21 result = place_order(prices, order)
22
23 print(result)

EDIT

I got as far as making the order into separate strings with this:

order = "pizza pizza water coke"
order = order.split()
total= 0
if order in prices:
total += prices.get(order)
print(total)
else:
total += 5.0
print(total)

Now the error I receive is that lists are unhashable. Hmm!

Answer 1

Justus thank you! I forgot that “if” statements aren’t loops. I know, that’s a silly mistake.
I actually solved this using a while loop! Here’s where I got to:

prices = {
"nachos": 6.0,
"pizza": 6.0,
"cheeseburger": 10.0,
"water": 4.0,
"coke": 5.0
}

order = input()
order = str(order)
order = order.lower()
order_list = order.split()
def place_order(dict, key):
n=0
total=0
while n <4:
if key[n] in dict:
total += dict.get(key[n])
n += 1
else:
total += 5.0
n += 1
total += total * .07
return total

print(place_order(prices, order_list))

Answer 2

My account isn't pro, so, don't know if this will pass all test cases.
Try using a for loop to iterate through the list .
Something like this
result =[]
for i in order:
if i in dictionary:
result.append(dictionary[i])
print(sum(result))
