Appending a list's elements to another list using a list comprehension

I have two lists: a = [1, 2, 3] b = [4, 5, 6] What I'd like to do is append all of the elements of b at the end of a, so that a looks like: a = [1, 2, 3, 4, 5, 6] I can do this using map(a.append, b) How do I do this using a list comprehension? (In general, is using a list comprehension pref

li.reverse() does not return a list it just changes the list li. val = 00110 is evaluated in base 8 try without leading 0s On 10/17/07, Ixiaus <[EMAIL PROTECTED]> wrote: > > I have recently (today) just started learning/playing with Python. So > far I am excited and impressed (coming from PHP b
