Python Forum

Hi everyone, I'm just starting my journey with Python.
Here is something I'm working on today. It is an interactive restaurant menu.
I'm able to get it to run with no errors/exceptions. There is a part of the program to have the guest
input an item to the menu. For some reason, this item is added but can't be ordered.
Everything else seems to work.

menu = "salad, pasta, sandwich, pizza, drinks, dessert "
print("Our menu is:", menu)

menu2 = input("Would you like to add something to the menu?")

menu3 = menu + menu2

print(menu3)

menu_ask = input("What would you like from the menu?") 

if menu_ask.casefold() in menu3:
	print("Yes, we have ", menu_ask, " tonight.")
else:
	print("Sorry, we don't have ", menu_ask, " tonight.") 

Here is an example of the output:

Our menu is: salad, pasta, sandwich, pizza, drinks, dessert
Would you like to add something to the menu? Pie
salad, pasta, sandwich, pizza, drinks, dessert Pie
What would you like from the menu? Pie
Sorry, we don't have Pie tonight.

I actually just got it to work. I had some lines of code commented out that I removed and now it works.

---

Now it's not working. Driving me nuts.

---

if menu_ask.casefold() in menu3.casefold():

This solved it.

After the crash some of my post are missing and seeing that maggotspawn has said that the code is working that was posted, I'm going to post my version of the solution.
Maybe it will help someone in the future

#! /usr/bin/env python3.8
'''Docstring'''
import sys
menu = ['salad', 'pasta', 'sandwich', 'pizza', 'drink', 'dessert']

print(f'Our Menu: {", ".join(menu).title()}')

ask = input('Would you like to add a menu item? y or n : ')
if ask == 'y':
    print()
    extra = input('What item would you like to add?: ')
    menu.append(extra)
else:
    pass
print()
print(f'Our Menu: {", ".join(menu).title()}')
order = input('What would you like from the menu? Seperate multiple items with a comma\n : ').split(',')

print('\nYour order:\n')
for item in order:
    if item.strip().casefold() in '\n'.join(menu).casefold():
        if item == '':
            print('You did not order anything.')
            sys.exit()
        else:
            print(f'{item.title().strip()} is on the menu')
    else:
        print(f'Sorry, {item.title()} is not on the menu.')

print()

Output:
Our Menu: Salad, Pasta, Sandwich, Pizza, Drink, Dessert
Would you like to add a menu item? y or n : y

What item would you like to add?: cherry pie

Our Menu: Salad, Pasta, Sandwich, Pizza, Drink, Dessert, Cherry Pie
What would you like from the menu? Seperate multiple items with a comma
 : salad, pizza, cherry pie, coke

Your order:

Salad is on the menu
Pizza is on the menu
Cherry Pie is on the menu
Sorry,  Coke is not on the menu.

Nicely done menator01. Makes my code look barbaric in comparison. Yours is case sensitive though.

Going to post one more example. This does not have the add item. Uses terminal colors.
I was going to post the output but, I could not do it in color so, I didn't.
