Python overwrite traceback call in objects

Question

我有一个深层嵌套的同一类对象，我想检测回溯属性错误，所以我可以打印（“此级别没有属性”）消息，而不是显示回溯属性错误消息。

Answer 1

You can use the try-except clause here:

try:
    #Your code here (Whatever thing gets to an attribute error)
except AttributeError:
    print("there is no attribute in this level")

Answer 2

Use the getattr magic method.

def __getattr__(self, name):
           print("there is no attribute in this level")
