要打印从根到叶的所有路径(其中一个空的子级" ). 例如Basic.DeviceInfo.DeviceInfo Form.DeviceInfo Form1
Want to print all paths from root to leaf(one with empty 'childrens'). E.g Basic.DeviceInfo.DeviceInfo Form.DeviceInfo Form1
一切正常，直到 DeviceInfo Form2
当涉及到 DeviceInfo Table (设备信息表)时，出现了 DeviceInfo表单-> Basic.DeviceInfo.DeviceInfo Form.DeviceInfo Table.DeviceInfo Table1.
When it comes to DeviceInfo Table, DeviceInfo Form is coming into picture --> Basic.DeviceInfo.DeviceInfo Form.DeviceInfo Table.DeviceInfo Table1.
这不应该发生.相反，我需要 Basic.DeviceInfo.DeviceInfo Table.DeviceInfo Table1.
This should not happen. Instead I need Basic.DeviceInfo.DeviceInfo Table.DeviceInfo Table1.
我的代码在哪里出问题了.有解决办法吗?
Where am I going wrong with my code. Any solution?
def walk(list1, path = ""):
for dic in list1:
#print('about to walk', dic['name'], 'passing path -->', path)
if(len(dic['childrens']) == 0):
print('leaf --->', path+dic['name']+'.')
else:
path = path+dic['name']+'.'
#passing parent name to childreni
walk(dic['childrens'], path)
推荐答案
您正在子句中设置path = path +dic['name']+'.'.一旦walk()函数完成了遍历DeviceInfoForm'childrens'之后，它将尝试遍历DeviceInfoTable.但是，您的函数已经将路径设置为Basic.DeviceInfo.DeviceInfoForm.
You are setting your path = path +dic['name']+'.' in your else clause. Once the walk() function has finished traversing through the DeviceInfoForm 'childrens', it attempts to traverse the DeviceInfoTable. However, your function has already set path toBasic.DeviceInfo.DeviceInfoForm.
您需要重新组织功能，以便在else:语句中未设置路径.也许
You need to reorganize your function so that the path isn't set in the else: statement. Perhaps
else:
walk(dic['childrens'], path+dic['name']+'.')
通过这种方式，您将正确的路径传递给函数，但未明确设置它.
That way you are passing the correct path to the function, but not explicitly setting it.
