Question

我正在尝试编写一个组织棒球运动员统计数据和信息的程序。我需要使用一个输入文件，其中包含要组织的所有数据，包括玩家姓名，团队，命中记录等。

我遇到了我定义的其中一个功能的问题，我不确定从哪里开始。每次我运行程序时，我都会在第73,25,53,49行中收到错误 - 所有这些都与name "processFile" is not defined有关。我不确定我是否应该将函数外部定义为变量？

我发布了目前为止的代码，以及我正在组织的数据文件。谢谢！

print("Welcome to The Baseball Database!")

def terminate():
    """This function quits the program"""
    userExit = input("Are you sure you want to quit? Yes or No?: ")
    userExit = userExit.lower()
    if userExit == "yes":
        print("The Baseball Database is terminating gracefully.")
        exit()
    if userExit == "no":
        introRerun()
    else:
        print("Please enter 'Yes' or 'No'.")
        terminate()

def assist():
    """This function offers help to the user"""
    print("The Baseball Database supports the following command functions:")
    print("INPUT - which allows you to input a file path")
    print("TEAM - which allows you to identify a team, and provide info about the players")
    print("REPORT - which reports the number of hits")
    print("HELP - for assistance")
    print("QUIT - to exit the database")
    print("Please choose from one of the above functions.")
    introRerun()

Answer 1

您定义processFile，但使用processFlie反转i和l ...只是错误的错字。

但您的代码中还有许多其他问题：

你有一个命令 loop 但只处理一次
您需要整个程序中的文件名称，但不要将其保留在任何地方
你试图打开......之前打开的结果！
如果您打开文件，则永远不会关闭该文件
在将myList调用None之前将其初始化为append（应该是：myList = []）

祝你好运，当所有问题得到解决后，它将会运行： - ）
