To my mind alist[0] should yield '0xce'

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

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?

Yes thats obvious.
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 at python.org will just open anew subject intead of replyign to an opened thread.
