Python Mini Project: Restaurant Ordering System

Introduction

• Instructor: साग
• Platform: pythonanywhere.com
• Focus on using dictionaries and conditional statements
• Each advanced concept will be followed by a mini project to reinforce learning

Project Overview

• Purpose: To create a simple restaurant ordering system
• Key Components:
  • Menu with items and prices
  • User input for placing orders
  • Calculation of total cost

Menu Items

• Items Available:
  • Pizza: ₹440
  • Pasta: ₹50
  • Burger: ₹10
  • Salad: ₹770
  • Coffee: ₹80

Program Workflow

1. Welcome Message: Display a greeting message to the user.
2. Display Menu: Show available items and their prices.
   • Use newline characters for better readability.
3. User Order Input: Ask the user for their first order.
4. Conditional Logic:
   • Check if the ordered item is available in the menu.
   • If available, add the item to the order and update total.
   • If not available, inform the user.
5. Additional Orders: Ask the user if they want to add more items.
   • If yes, repeat the order input process.
   • If no, display the total amount to be paid.

Code Structure

• Menu Definition: menu = { 'Pizza': 440, 'Pasta': 50, 'Burger': 10, 'Salad': 770, 'Coffee': 80 }
• User Interaction:
  • Use input() to gather orders.
  • Use formatted strings to display messages.
• Order Total Calculation:
  • Use a variable to keep track of the total price.
  • Update total whenever a new item is added.
• Error Handling:
  • If a user inputs an unavailable item, prompt to order something else.

Final Steps

• Display the total amount to the user.
• Program should ideally loop until the user decides to quit.

Next Steps

• Future Learning: Introduction to loops to allow continuous ordering until the user exits.
• Assignment: Create a phone book application using dictionaries to practice learned concepts.

Conclusion

• Reinforces understanding of dictionaries and conditional statements.
• Encourages practical application through project work.
• Feedback and experiences are encouraged in comments.
