I don't care, frankly. I'm still not going to help anyone to break CAPTCHAs automatically. If you're unable to solve CAPTCHAs, it's equivalent to being unable to run VBScript or unable to download music over a proprietary streaming protocol: it's a problem to be solved by getting the server admin to change policy, *not* by trying to script around it. Scripting around the problem just forces everyone to make it harder to script around the problem. You're joining the arms race, and on the wrong side. Breaking CAPTCHAs is *not* good for any issue.

In other words, you have a task to make a robot that can break the procedures put in place to prevent robots from posting to web sites... The whole purpose of the CAPTCHA scheme is that computer AI systems aren't advanced enough to process them, whereas a human mind can almost do it in the subconscious. (as for picture attachments? comp.lang.python is a text newsgroup -- binaries aren't wanted in it; c.l.p is also gatewayed to a mailing list; and that mailing list is gatewayed to gmane.comp.python.general where it is made available as a news group (after spam filtering). Google Groups links to c.l.p (and many of us wish it didn't) -- Wulfraed Dennis Lee Bieber AF6VN wlfr...@ix.netcom.comHTTP://wlfraed.home.netcom.com/ -- https://mail.python.org/mailman/listinfo/python-list

I am now the third person to do you the courtesy of a response, but there are lots more who are simply deleting your post and moving on, or possibly marking you as a spammer, because that's about the only reason for wanting a program to solve CAPTCHAs. Let me spell it out for you: NO WE WILL NOT do this for you. And if you do it yourself, we will not be happy. Just don't. ChrisA -- https://mail.python.org/mailman/listinfo/python-list

Yeah, that is the most likely scenario. If I'm courteous, I'll assume that he has no idea what the rest of the world thinks of this kind of thing.

Re: Captcha identify
If my questions make you guys not so happy, I am sorry and please just ignore. I just wanna a general suggestion here in the beginning. Why I need to write such program is just having such requirements, and has nothing to do with the coding work itself. Don't say something to prove you're so noble. -- https://mail.python.org/mailman/listinfo/python-list

Many of us here use CAPTCHAs and spend time keeping one step ahead of those who try to break them with software. By writing something to solve CAPTCHAs, you would be stealing time from those people. Don't do it. Am I sufficiently clear? ChrisA -- https://mail.python.org/mailman/listinfo/python-list

Wesley nisp...@gmail.com writes: If my questions make you guys not so happy, I am sorry and please just ignore. You seek to dismiss the valid concerns by calling them “not so happy”. You assert it is questions we object to, when we are clearly objecting to your intentions. Don't be disingenuous. The responses you get are because there are valid concerns about the motives you are pursuing. Why I need to write such program is just having such requirements This is a circular statement, almost a tautology. If that is the best you can present in defense of harmful and deceitful actions, then there is no good reason for what you're doing.
