如何通过用户输入检查txt文件中是否存在多个字符串？

我正在尝试创建一个程序，该程序将跟踪玩家的输赢率，现在，我正在尝试让该程序检查txt文件中是否列出了某个名称，但该名称始终返回false。

因此在内部def check_player，当我输入名字时，它说它在列表中，但是我输入的所有后续名字都返回为false。.txt文件的内容是7个名称，我输入的名字也是列表中的名字，为什么它不检查整个文件以查看名称是否存在？

编辑：我发现一种更简单的方法来解决此问题。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

我认为您应该将“ return False”归为一个级别，然后删除其他级别。我认为现在是这样，check_player只看第一行。
