Answer 1

>>> class Test:
...     def __init__(self,a):
...             self.a=a
...     def sqrt(self):
...             return self.a**0.5
...
>>> t = Test(2)
>>> t.sqrt()
1.4142135623730951
>>> Test.__mro__
(<class '__main__.Test'>, <class 'object'>)
>>> Test.__mro__[0]
<class '__main__.Test'>
>>> Test.__mro__[1]
<class 'object'>

You can see your object position, name and also type.
