Menu loop

As explained in A Pythonic Adventure: From Python basics to a working web app

A menu loop repeatedly prompts for a menu selection until the input is accepted or the menu is exited.

A menu loop keeps prompting until the user selects an allowed item or chooses to exit. It prevents mistakes such as typing coffee when the program expects a number, or entering 42 when the list has only three choices. section 4.0

A complete order

Entering x at the drink, flavor, and topping menus produces an empty order and continues to the final confirmation.

How A Pythonic Adventure: From Python basics to a working web app covers it

How deep it goes
Explains dynamic validation, loop repetition, breaking, nested conditions, and exit returns through a complete Python function.
Examples
Demonstrates drink, flavor, and topping menus, invalid entries, dynamic allowed-answer lists, and an all-exit empty order.
What it assumes
Assumes basic Python functions, lists, loops, conditionals, input, and indentation while reinforcing them through a practical menu.
What you can do after
Build it from scratch as a reusable Python menu function that validates choices, repeats prompts, and exits cleanly.
How it connects
Connects input validation with while loops, break statements, functions, lists, nested if statements, and error messages.
