Python Class – How to Get Class Object from Class Name String

I have a class

class Foo():
    def some_method():
        pass

And another class in the same module:

class Bar():
    def some_other_method():
        class_name = "Foo"
        # Can I access the class Foo above using the string "Foo"?

I want to be able to access the Foo class using the string "Foo".

I can do this if I'm in another module by using:

from project import foo_module
foo_class = getattr(foo_module, "Foo")

Can I do the same sort of thing in the same module?

The guys in IRC suggested I use a mapping dict that maps string class names to the classes, but I don't want to do that if there's an easier way.
