Yes, you can use __dict__ on the class object and on instances. Example 
Python interactive session:

>>> class t:
...   def hello(self):
...     self.data1 = "hello"
...
>>> x = t()
>>> x.__dict__
{}
>>> t.__dict__
{'__doc__': None, '__module__': '__main__', 'hello': <function hello at 
80e5df0>}
>>> x.hello()
>>> x.__dict__
{'data1': 'hello'}
