Do you have to use string versions of the class names?
Why not:

class Mark: mark = 42
class big(Mark): pass
class boss(Mark): pass
class two(Mark): pass
class three(Mark): pass

markersExp = [big,boss.two,three]

for cls in markersExp: print cls.mark

Classes are objects too!

Or are we really talking about instances? In which case the usual solution 
is a dictionary.
