<nit>
That's the usual idiom, but it should be noted that
it's not exactly the same, e.g.,
>>> class A: pass
...
>>> class B(A): pass
...
>>> a=A(); b=B()
>>> isinstance(a, A)
True
>>> isinstance(b, A)
True
>>> a.__class__.__name__ == 'A'
True
>>> b.__class__.__name__ == 'A'
False
That last, again, is not the same as
>>> isinstance(b, A)
True
</nit>
