Use the URL specified as the <form>'s action, which in this case is
https://passport.baidu.com/?login , rather than the URL of the login
page itself.
The <form> fields aren't called "username" and "password"; read the
page's HTML. You'll also see that there are a few hidden form fields
that are probably required.
Finally, even if you fix these problems, the site could possibly block
Python based on its User-agent header.

Cheers,
Chris
