Sorry Franz, as you are using python 2.6 you have to use d1 = dict(('list_' + str(i), []) for i in range(3)) d2 = dict(('list_' + str(i), [m for m in range(3)]) for i in range(3)) like stated here: http://stackoverflow.com/questions/1747817/python-create-a-dictionary-with-list-comprehension -- http://mail.python.org/mailman/listinfo/python-list
