想要打印从根到叶的所有路径（其中一个路径的“childrens”为空）。例如基本.DeviceInfo.DeviceInfo窗体设备信息表格1

一切都很顺利，直到DeviceInfo Form2

当谈到设备信息表时，设备信息表就进入了画面-->基本.DeviceInfo.DeviceInfo窗体设备信息设备信息表表1。

这不应该发生。相反，我需要基本.DeviceInfo.DeviceInfo设备信息表表1。

我的代码哪里出错了。有什么解决办法吗？在

Answer 1

您正在else子句中设置path = path +dic['name']+'.'。一旦walk()函数完成了对DeviceInfoForm“childrens”的遍历，它将尝试遍历DeviceInfoTable。但是，您的函数已将路径设置为 Basic.DeviceInfo.DeviceInfoForm.

您需要重新组织您的函数，使路径不在else:语句中设置。也许吧

else:
    walk(dic['childrens'], path+dic['name']+'.')

这样您就可以将正确的路径传递给函数，而不是显式地设置它。在
