我目前正在编写一个程序来修改机器人的偏移值,这些值以文本形式存储在程序中。我已经设法完成了大部分功能,但我对最后一个功能有问题。它是re.sub公司方法。我一直收到一个错误消息:
raise TypeError(“第一个参数必须是string或compiled pattern”) TypeError:第一个参数必须是string或compiled pattern。在

但是在我看来,第一个参数是一个编译模式。如果有人有什么建议的话,我可以帮你解决这个问题。这是有问题的部分。它的submit_x_offset函数。同样,is似乎删除了整个文件,同样的regex语句在find_x_offset中工作得很好,而当前还没有编译它。在
