They are often more efficient but I don't know if I'd ever claim they were easier to read than an explicit for loop. Perhaps the most trivial cases like z = [x*2 for x in L] and even then I'm not sure that is easier to read than z = [] for x in L: z.append(x*2) And personally I still find map() easier for those cases z = map(lambda x: x*2, L) But you do need to be comfortable with lambda for that, and lambda is just as hard to grok as list comprehensions! :-) Alan G. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
