I think it depends on which namespace the class lives in,
and where you want to get at it from.

In the interactive interpreter, you might do:

class Foo:
    pass
instance = locals()['Foo']()



If the class lived in a module, say FooMod.py you could do:

# FooMod.py
import FooMod

class Foo:
    pass
instance = getattr(FooMod, 'Foo')()
