我正在尝试创建一个程序来跟踪玩家的胜负率,现在我正在尝试让程序检查某个名称是否列在 txt 文件中,但它始终返回 false。所以在里面def check_player,当我输入第一个名字时,它说它在列表中,但我输入的所有后续名称都返回为 false。.txt文件的内容是7个名字,我输入的第一个名字也是列表中的第一个名字,为什么它不检查整个文件以查看该名字是否存在?编辑:我找到了一个更简单的方法来解决这个问题。考虑这个关闭def NewGame(): print("how many people are in this game?") people = int(input()) for num in range(people): #does it n times where n is the number of players print("who is the Player in this game?") player = input() file_name = "Player_List.TXT" #initializes the name of the file it is pulled from check = check_player(file_name, player) #go to def check_player and pass file & player if check == False: print("this player is not in the system.") print("would you like to add them(Y/N)?: ") add = input() if add == "Y" or "y": AddPlayer()def check_player(file_name, player): """ Check if any line in the file contains given string """ # Open the file in read only mode with open(file_name, 'r') as read_obj: # Read all lines in the file one by one for line in read_obj: # For each line, check if line contains the string if player in line: return True else: return False
