Today's activity involves practicing file operations in a small game where the user can store magic items. The main difficulties encountered were with the list.remove() function and understanding the instructions correctly. The code includes functions for adding, removing, and viewing items in the inventory. The program continuously prompts the user for input and saves the inventory to a file.

Record#

Today there is no new knowledge point to learn, it is a comprehensive exercise on file operations.
Today's task is to create a small game that stores user-inputted magic items.
The biggest difficulty encountered today is the use of list.remove(), and also misunderstanding the task.

CODE#

import os, time
try:
  f=open("gamelist.txt","r")
  gamelist=eval(f.read())
  f.close
except:
  gamelist = []

def gameadd():
  gname = input("Input the item to add: > ").capitalize()
  gamelist.append(gname)
  print(f"{gname} has been added to your inventory.")
  

def gameremove():
  if gamelist:
    gname=input("Input the item to remove: > ").capitalize()
    if gname in gamelist:
      gamelist.remove(gname)
      print(f"{gname} has been removed from your inventory.")
    else:
      print(f"{gname} is not in the list.")
  else:
    print("The list is empty")

def gameview():
  if gamelist:
    gname=input("Input the item to view: > ").capitalize()
    if gname in gamelist:
      gamenum = gamelist.count(gname)
      print(f"You have {gamenum} {gname}.")
    else:
      print(f"{gname} is not in the list.")
  else:
    print("The list is empty")

while True:
  time.sleep(1)
  os.system("clear")
  print("🌟RPG Inventory🌟")
  menu=input("1: Add\n2: Remove\n3: View\n")
  if menu == "1":
    gameadd()
  elif menu == "2":
    gameremove()
  elif menu == "3":
    gameview()
  else:
    print("input error")
    
  f=open("gamelist.txt","w")
  f.write(str(gamelist))
  f.close()
