从文件中读取行时出错（Python）

我正在制作一个程序，您可以创建自己的骰子，然后使用它。 在我的代码顶部，我试图将骰子文件中的所有6行放入列表中。 当我运行代码并按“加载骰子”时，出现此错误：btnDie = tkinter.Button（frameCustomDice，text = os.path.splitext，command = read_dice_lines（dice_file_name）[0]）TypeError：read_dice_lines（）需要0个位置参数，但给出了1个，我该如何解决？ 任何帮助都感激不尽。

Answer 1

您需要将该参数添加到要接受的函数中。 当前是def read_dice_lines():

更改为：

def read_dice_lines(dice_file_name):

请注意，在此处调用command=read_dice_lines(dice_file_name)[0]您将遇到其他问题，因为read_dice_lines不返回任何内容，因此默认为None 。 然后，您尝试获取无的第一个元素[0] ，这将引发错误。 因此，您将需要删除[0]或返回列表，元组或可索引的内容。
