coding improvement tips

[vaisesumit29]

Hi All,
I am apologizing in advance if it wastes your time. Because it's not a question regarding any topic. It is for my improvement. Experts can suggest to me what would be the better option that could be used. I believe Feedbacks are the best way to improve oneself.
So here is my project. Its a simple project of a restaurant.
Flow:
Code as user whether he would like to order something?
If it's Yes --> The code displays the menu
---> Ask for the food items he would like to place?
---> Once the user is done with the order. A final bill is displayed.

Restaurant.py

""" This module is a restaurant program.
    Ask user input to place an order. Provide multiple options to user
    to choose. """
