Any one who was Succeed in this challenge?

Answer 1

I succeeded.

If you would like help you should post your code attempt :)

Answer 2

Try this:

Change 'order=input()' to 'order=input().split()'. This will allow multi line input and split the input into a list

Then iterate through the list and check for each item in the dictionary. I used a 'for loop' to do this.

Answer 3

Keith
The code running by seccssfully
Percentage 98% (the my code process).

I think i must move forward to complete all courses about python to gain more skills and find Another method to write it

Answer 4

Keith
This is my attempt
menu={"Pizza": 6 , "Nachos": 6 ,"Cheeseburger": 10,"Water": 4,"Coke": 5}
order=input()
if order in menu:
tax=menu.get(order)*0.07
cost=menu.get(order)+tax
print(cost)

The problem is my code is running with only single word input not multi input in same statment

Answer 5

Hi, Mohammed Hassan !

Start by ensuring your code can handle multiple items from the input. Consider, for example, using a loop or comprehension to process each item in the input string. Then implement a default case for items not on the menu. You might find the ‘.get()’ method with a default value useful for this purpose (see below; a solution you can compare your code with):

print(round(1.07 * sum({"Nachos": 6, "Pizza": 6, "Cheeseburger": 10, "Water": 4}.get(i, 5) for i in input().split()), 2))

Answer 6

I used a for loop and if/else statement:

# Iterate through order and calculate cost
for i in order:
if i in items_dict:
(do stuff)
else:
(do something else)

There are many ways to accomplish this task, including List Compression but this is probably easier to understand for beginners.

Mohammed Hassan What does your code look like now? Post an update of your code so others can help you 👍

Answer 9

I modified your code and this should work:

menu={"Pizza": 6 , "Nachos": 6 ,"Cheeseburger": 10,"Water": 4,"Coke": 5}
cost=0.0
order=input().split()
#order=list(order_1)
for i in order:
if i not in menu:
tax=menu.get("Coke")*0.07
cost=cost+tax+menu.get("Coke")

else:
tax=menu.get(i)*0.07
cost=cost+menu.get(i)+tax
print(cost)

Changes I made:

1. You do not need 'order=list(order_1)' because the input statement already creates a list.
2. 'cost' should be initialized as a float, not an integer.
3. I changed the for statement to 'for i in order:', now 'i' will represent each item.

I posted this code earlier, that just needed to be completed:

Your on the right track and should be able to complete the challenge now!

Answer 10

I use dictionary for menu, and loop calculation.
Here my code for reference :

edit: oh sorry, i dont realize if this question for phyton, and im use java. but i think the logic and method maybe same

Answer 11

I Already do this method but the code need much more optimization

Answer 12

Per Bratthammar
Ok if there is a item not found in menu in the for processing how can the code looks like this is my risk now

These is small mistake i don this code in another application

Answer 14

Well itried it using C (rn) and still fail.
