To my mind alist[0] should yield '0xce' > Is that treating alist as a string? No, of course not. Strings are not > > the only object that have indexing object[position]. Yes actually it does. s string is a series of characters. a list is a series of objects, which can be chars, strings, integers, other data structures. So doing a_list[0] is similar of doing a_string[00 > > > A byte object is a sequence of bytes (= integer values) and support > > indexing Isn't a byte a series of zeros and ones, like 01010101 ? So why you say bytes are integers since its numbers into a binary system? perhsp you mean a represantaion of a bye to a decimal value? > I am not saying this to insult you, or to be rude.

What is not obvious is how you reply back to a thread by giving extra info when you are not replying to a mail formt tha thread or when you ahve deleted the reply for a member sending the mail to python-list@python.org will just open anew subject intead of replyign to an opened thread. -- http://mail.python.org/mailman/listinfo/python-list
