sir , i am very new to python i have just started to learn it ,

my aim is to practice
1)simple automatic form registration,
2)simple automatic vitrification
3)simple automatic loging

this site http://goarticles.com/register.html

sir i m referring the mechanize module

now i am stuck on two thing

1) how to automatically handling the captcha on this form
2) how to verify or the filled form

please help i have already gave 2 days on this just i want some clue from ur side

You've asked the same question twice now. You have received the only answer that
you are going to get here: we won't help you do this. We may help you learn to
do other stuff with Python, but not this. Please stop asking this question.

Jai,

The first time you asked for help you used all capital letters. People usually don't take that well, since it is like yelling.  As Robert pointed out, you then asked the same question again.  This is also not good.  Then you complain that you haven't been given service in two days.

So, what you need to do is show a small coding example of the problem you are having.  Give the OS, the python version, and copy the traceback if there is an error.

And give a good solid reason why you need to automate a CAPTCHA,
because none of us here wants to contribute to the eternal problem of
spam.

The OP seems to be a kind of 'drive by' questioner.  He yells out his plea as his ride cruises by.  Around the block and yell again.

The purpose of a captcha is to prevent automated scraping of data. Many
of us may choose, or even need, to use captcha. What on earth makes you
think for one minute that we'll help you bypass them.

I have the same issue, nothing find a solution yet!

[MRAB]

The purpose of captcha is to ensure that talking to a human, not a bot.
It does that by presenting a task that's impossible, or at least
extremely difficult, to do, so it's not surprising that you haven't
found a solution.

Step 1: ‘import mechanize’.

Step 2: be an actual human, and interact manually with the CAPTCHA.

If you are attempting to fool a CAPTCHA with an automated tool, you are
entering an arms race against those who design the CAPTCHA to *prevent*
exactly what you're doing.

Any technique someone can describe to fool the CAPTCHA, will most likely
already be considered as part of the design of the more effective
CAPTCHAs, and so the technique will still not actually work reliably.

So, there is no general answer, other than to stop thinking that's a
race that you can win.

And any technique that someone can describe to fool programs will most
likely already be considered by those who write programs to break
captchas, and so the technique will still not actually work reliably.

I agree that there is no *general* answer. For any specific captcha,
there probably is a way to break it automatically, and possibly with
higher reliability than a human can (many captchas are hard and
frustrating for humans).

It *is* an arms race and who wins depends on who where to break-even
point between effort and value is for the defender and the attacker.
