我正在嘗試創建一個程序來跟蹤玩家的勝負率，現在我正在嘗試讓程序檢查某個名稱是否列在 txt 文件中，但它始終返回 false。所以在里面def check_player，當我輸入第一個名字時，它說它在列表中，但我輸入的所有后續名稱都返回為 false。.txt文件的內容是7個名字，我輸入的第一個名字也是列表中的第一個名字，為什么它不檢查整個文件以查看該名字是否存在？編輯：我找到了一個更簡單的方法來解決這個問題?？紤]這個關閉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
