Rather than using eval, you can grab the class out of globals(), and
then use getattr to get the methods.

>>> for s in urls :
...     o = globals()[s]()
...     for method in strings :
...         getattr(o, method)()
...
Abc good
Abc better

And for getting the class name, the class has a __name__ attribute. So
you could use self.__class__.__name__.
