How about something like this:


############
#make object:

class S(object):pass
class X(object):pass
class Y(object):pass

s = S()
s.components = X()
s.components.d1 = Y()
s.components.d1.text = "hello world"

###########

obj = getattr(s.components, "d" + str(1))
obj.text = "goodybe"
print s.components.d1.text
