That is not treating it as a string, and it does not present the first character. It presents the first byte, which is a number between 0 and 255, not a character. py> alist = [0xce, 0xb1] py> alist[0] 206 Is that treating alist as a string? No, of course not. Strings are not the only object that have indexing object[position]. > 's' is a byte object, how can you treat it as a string asking to present > you its first character? You just asked that exact same question.

Nikos, you fail basic computers. Time for you to step away from the computer, go to the library, and borrow a book about the basic fundamentals of how computers work. Perhaps something written for school children. I am not saying this to insult you, or to be rude. But you are obviously struggling with the most basic concepts, like what a byte is. You need to go back to basics and learn the simple things, and perhaps if it is explained to you in your native language, you will understand it better. > > Because your method doesn't work. > > If you use all possible 256 bit-combinations to represent a valid > > character, how do you decide where to stop in a sequence of bytes? > > How you mean? please provice an example so i can understand this.

Can you pleas ebut it simple. Nikos, if you can't be bothered to correct your spelling mistakes, why should we be bothered to answer your questions? It takes you half a second to fix a typo like "pleas ebut". It takes us five, ten, fifteen, twenty minutes to write an email explaining these concepts, and then you don't bother to read them and just ask the same question again. And again. And again. > ps. i tried to post a reply to the thread i opend via thunderbird mail > client, but not as a reply to somne other reply but as new mail send to > python list. > because of that a new thread will be opened.
