Specifications

• In your program, use this text file: wizard_all_items.txt for a list of all the items and create a new text file: wizard_inventory.txt to store the items that the wizard is currently carrying.
• Your program should define the following functions:
  • main( )
  • read_items( ): Reads all items from wizard_all_items.txt
  • read_inventory( ): Reads all items from wizard_inventory.txt
  • write_inventory( ): Updates wizard_inventory.txt
  • display_title( ): Displays the application title
  • display_menu( ): Display the command menu
  • walk( ): Picks one item randomly
  • show( ): Shows all items in the inventory
  • drop( ): Drops one item from the inventory
• When the user selects the walk command, the program should read all items from the file, use random.choice( ) to randomly pick one item from the list, and give the user the option to whether grab it or not.
• The wizard can only carry four items at a time.
• Make sure to update this file every time the user grabs or drops an item.
• For the drop command, display an error message if the user enters an invalid number for the item.
