看起来错误是您在
,上分割goldmedals.txt中的行，但文件中的字段实际上是用\t分隔的。当你在不存在的
,上进行分割时，你会得到一个只有一个字符串的列表。你的命名元组需要四个参数，所以当你用一个元素展开你的列表时，它会告诉你你缺少了四减一或三个参数。现在，您的数据包含许多选项卡，因此如果您按选项卡拆分，您需要将前四个结果切片并将其扩展到
Medal构造函数中，否则您将获得有关提供过多参数的错误。jq6vz3qz2#
我看不出你问的实际问题，所以如果你已经知道这一点，请道歉，但是你得到的错误源于这样一个事实，即你正在对包含逗号（，）的有效数据执行line.split（'，'），例如。"速滑女子1,000米"对于像这样的行，它会在逗号处分裂成1,000分.那么当你试图构造Medal（）时，它将没有足够的参数。请尝试在制表符（'\t'）处拆分。
