You canot sneak a statement like > a = a + 1 into a list comprehension, you have to modify the expressions. Given [[...] for a in range(2, 5) for b in range(3)] what expression replacing the ... would give the expected result? Hint: it depends on both a and b. Once you have figured it out you can try and reshuffle it a bit into [[b] for a in range(2, 5) for b in range(...)] _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
