Interactive Menu, String Search?

[maggotspawn]

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.
