For Python:

Create a program that keeps track of the items that a wizard is carrying.

*Your instructor should provide a text file named wizard_all_items.txt that contains a list of all the items that a wizard can carry.

* You should create another text file named wizard_inventory.txt to store the current items that the wizard is carrying.

* A wizard can only carry four items at time, and those four items must be different.

* When the user selects the walk command, the program should read the items from the file, create a list of the items that aren't already in the wizard's inventory, randomly pick one of those items, and give the user the option to grab it. To create a list of the items that aren't already in the wizard's inventory, you can use a list comprehension as described in chapter 6.

* Make sure to update the inventory text file you created every time the usher grabs or drops an item.

*For the drop command, display an error message if the user enters an invalid number for the item.

*(Code must be placed in functions)

Here is what I have so far.

import random

def read_items(): f = open("wizard_all_items. txt", "r") items = [] for item in f: items.append(item)

f.close() return items

def read_inventory(): f = open("wizard_inventory.txt", "r") invenrtory = [] for item in f: inventory.append(item)

f.close() return inventory

def write_inventory(inventory): f = open("wizard_inventory.txt", "w") for item in inventory: f.write(item) f.close()

def display_title(): print("The Wizard Inventory Program ")

def display_menu(): print("COMMAND MENU") print("walk - walk down a path") print("show - show all items") print("drop - drop an item") print("exit - Exit program")

def walk(): items = read_items() inventory = read_inventory()

random_item = random.choice(items) print("While walking ddown a path, you see", random_item) option = input("Do you want to grab it? (y): ")

if option == "n": print("You didn't picked up ", random_item)

else: total_item = len(inventory) if total_item == 4: print("You cannot carry any more items. Drop something first. ") else: print("you picked up", ranom_item) inventory.append(random_item) write_inventory(inventory) def show(): f = open("wizard_inventory.txt") index = 1 for item in f: item = item.strip() print("%d. %s" %(index, item)) index += 1

def drop(): num = int(input("Number: ")) inventory = read_inventory() total_item = len(inventory) if num total_item: print("Error. Invalid item number.") else: print("You dropped", inventory[num -1]) inventory.pop(num-1) write_inventory(inventory) def main(): display_title()

display_menu()

while True: command = input(" Command: ") if command == "walk": walk() elif command == "show": show() elif command == "drop": drop() elif command == "exit": break else: print("Error. Invalid command.") print("Bye!")

if __name__ == "__main__": main()

Project 7-2: Wizard Inventory Create a program that keeps track of the items that a wizard is carrying. Console The Wizard Inventory program COMMAND MENU walk - Walk down the path show - Show all items drop - Drop an item exit - Exit program Command: walk While walking down a path, you see a scroll of uncursing. Do you want to grab it? (y):y You picked up a scroll of uncursing. Command: walk While walking down a path, you see an unknown potion. Do you want to grab it? (y) : y You can't carry any more items. Drop something first. Command: show 1. a wooden staff 2. a scroll of invisibility 3. a crossbow 4. a scroll of uncursing Command: drop Number: 3 You dropped a crossbow. Command: exit Bye!
