CIS115 Week 6 Lab Overview

Title of Lab: Shopping List in Python

Summary

Create a program that will allow a user to add, list, and delete items from a shopping list.

Deliverables

• A source code Python file.
• A Word document containing both source code and the screen print of the program outputs.

Lab Steps

The program should be modular. For example, you will want to have an add_item(shopping_list) function, a delete_item(shopping_list) function, a display_list(shopping_list) function, a display_menu() function, and a main().

Sample Output:

Welcome to the program!

1. Add an item

2. List all items

3. Delete an item

4. Exit

Enter a menu option: 2

1 : bananas

2 : apples

Enter a menu option: 1

Please enter the item: pears

pears was added to the shopping list

Enter a menu option: 2

1 : bananas

2 : apples

3 : pears

Enter a menu option: 3

Which number to delete: 3

pears was deleted

Enter a menu option: 2

1 : bananas

2 : apples

Enter a menu option: 4

have a great day!

Specifications:

• The program should start with 2 items in the shopping list.
• Don't forget to include at the end of the program the code:
  • if __name__ == "__main__": main();
• Use this code for the delete_item(shopping_list) function:

def delete_item(shopping_list):

 number=int(input("Which number to delete: "))

 if number<1 or number>len(shopping_list):

 print("Invalid number ")

 else:

 item=shopping_list.pop(number-1)

 print(item," was deleted ")

 print()
