格式化代码的正确方法是什么？

Question

1. 我一直试图解决我的脚本没有结果。我无法显示负载数据。它保存在members.txt中，如果打开则可以手动读取。如果有人可以就整个脚本提供任何其他建议，我们将不胜感激。 我已经重新定义了大大改变的脚本周围仍然没有运气。 如果vars（）中的'file'导入os：wk_dir = os.path.dirname（os.path.realpath（'file'））else：print（'我们以交互方式运行脚本'）class playerCLass（object）：name =“”phone =“”数字= 0

      def __init__(self, name, phone, number):

Answer 1

如果您的问题特别没有让printPlayer工作，您可以这样做

def printPlayer(players):
    print("Current members: ")
    if len(players) == 0:
        print("No current members in memory.")
    #Iterate through dictionary of player name and player object and call
    #display data on each of them
    else:
        for name, player in players.items():
            print(player.display_data())

如果你根据你写的语句运行代码和输入，你应该得到这样的东西。
