Question

Grocery List Program

• Write a program that keeps track of the user's grocery list items.
• Prompt the user if they'd like to (each action is a function):
• See the list
• Display all items (if any) in the list
• Add item to their list
• Confirm with the user before adding item (y/n or yes/no)
• If they enter a duplicate item, notify them the item already exists
• Remove items from their list
• Confirm with the user before removing item (y/n or yes/no)
• Search for items in their list
• Allow user to search for items
• Display the items found (if any) or notify user if nothing is found
• Your program must perform error checking
• Be sure to code this as a stand alone module
• __name__ == "__main__"
• Be sure to use functions to break apart and modularize your code
• The main part of your program must be simple with mostly function calls
• I will remove points if your main is not broken apart into modules

please make input functions. For example, you need to confirm with the user when removing or adding, both are yes/no (y/n) responses, these can call the SAME function which will take care of making sure the input is valid.

    

  

Programming language: Python

Requirement: Please tightly follow up the rules and provide multiple functions. The output needs to be exactly the same and use try except valueerror to control input.
