Ermmm... Maybe I should give a bigger example? What's better, this

from program.modules.class1 import class1
from program.modules.class2 import class2
from program.modules.class3 import class3
from program.modules.class4 import class4
from program.modules.class5 import class5
from program.modules.class6 import class6
from program.modules.class7 import class7
from program.modules.class8 import class8
from program.modules.class9 import class9
from program.modules.class10 import class10
from program.modules.class11 import class11
from program.modules.class12 import class12
from program.modules.class13 import class13
from program.modules.class14 import class14
from program.modules.class15 import class15
from program.modules.class16 import class16
from program.modules.class17 import class17
from program.modules.class18 import class18
from program.modules.class19 import class19
from program.modules.class20 import class20

or this

from program.modules import (class1,  class2,  class3,  class4, 
                             class5,  class6,  class7,  class8,
                             class9,  class10, class11, class12,
                             class13, class14, class15, class16,
                             class17, class18, class19, class20,
                             class21, class22, class23, class24,
                             class25, class26, class27, class28,
                             class29, class30, class31, class32,
                             class33, class34, class35, class36,
                             class37, class38, class39, class40)

???

If you mean doing "from program.modules import *" of course you *can*,
but you *shouldn't*. It makes your code a mess after some time.
