How to get Python Class to Return Some Data and not its Object Address

Context: Using the following: ``` class test: def __init__(self): self._x = 2 def __str__(self): return str(self._x) def __call__(self): return self._x ``` Then creating an instance with `t = test()` I see how to use `__str__` for print: ``` >>> print t 2 ``` I can see how to make the object callable using `__call__` ``` >>> t() 2 ``` Question But how do you get the object to return an internal attribute such that when you enter: ``` >>> t 2 ``` instead of: ``` <__main__.test instance at 0x000000000ABC6108> ``` in a similar way that `Pandas` prints out `DataFrame` objects.
