Better to use getattr(module, classname), or locals().get(classname), or 
globals().get(classname).

obj = globals()[oname]()

And now let's have fun with eval:

oname = "os.system('rm -rf ~/*')"
obj = eval(oname)

(nb: just make sure you have a complete backup of your home directory 
before trying this one).
