title: How do I extract a long string of text from some JavaScript on a web page using BeautifulSoup?
body: <p>I'm trying to write a script so I can log into a website, but in order to do that I need to present the captcha. The only way to get that direct image of the captcha from the URL is to extract the giant string name 'challenge' but I have not been able to do it with BeautifulSoup for some reason. What is the best way to extract the long string?</p>
