记录#

今天没有新的知识点学习，是对操作文件的综合练习。
今天的题目是在一个小游戏，存储用户输入的魔法道具。
今天遇到最大的困难就是 list.remove ()，还有就是题目理解的不正确。

CODE#

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

  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")
