Code Coach Ballpark Orders - Can't spot my mistake

Question

Hey folks, maybe someone can point my mistake out to me? 4 out of the 5 tests are positive, but the fifth hidden one isn't. In my mind my code should work.. I'd appreciate if someone can tell me what my mistake is.
Here's my code:

order=input()
total=0
menu=["Pizza","Nachos","Cheeseburger",
"Water","Coke"]
i=0
x=0
while i < 5:
if order.count(menu[i])>0:
x=x+order.count(menu[i])
if i==0 or i==1:
total=total+6*order.count(menu[i])
elif i==2:
total=total+10*order.count(menu[i])
elif i==3:
total=total+4*order.count(menu[i])
else:
total=total+5*order.count(menu[i])
i+=1

total=total+(4-x)*5
total=total*1.07
print(round(total,2))

Thanks, and best regards,
Aaron

Answer 1

Suppose your friend orders Fries. How does your code handle this case?

Answer 2

Ah, I think I get the idea!

Suppose your friend orders Watermelon. Your code finds "Water", and adds "Water" instead of "Coke". Could that be the issue?

Answer 3

I did the following: the variable "x" counts how many orders were made from the menu. So if all orders were from the menu, then x is 4 and nothing is added. But if someone ordered Fried or anything else of the menu, the x counter would be lower than 4 and I would order that many Cokes. (the code line: total=total+(4-x)*5)
That should work fine right?!

Answer 4

Oh absolutely, that makes sense. I didn't consider that option.
Thanks for your help Lisa! I appreciate it.
