I know what's wrong. Thank you. And I think
try:
    return self.__dict__[attr_name]
is unnecessary, because python will do it itself for us.

So now I have to overload __str__, but how can I make self.__str__
print as builtin str(): at here, I want get the result like:
<test instance at 0xb7bbb90c>
?
