Exactly; by the time __getattr__ is called, you already know attr_name
I'm sorry but I still have a question, look at this example:
>>> class test:
... def __init__(self):
... self.x = 1
... def __getattr__(self, attr_name):
... print attr_name
... if attr_name == 'y':
... return 2
... else:
... raise Att
return hex(id(self))

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:
?

Now I have to design a class that overload __getattr__, but after that, I
found the __repr__ have been affected. This is a simple example model:
#!/usr/bin/env python
class test:
def __init__(self):
self.x = 1
def __getattr__(self, attr_name):
try:
return self.__dic
