Awesome. Clear and straight to the point.

Could you write the code that uses a list containing three characters and then asks a user to enter a character. The code will then search the list to see if the entered character is in the list or not. If it’s not in the list, then the user is asked to enter a different character. This loop keeps repeating until the user enters a character which IS present in the list.
