title: How to get current URL from Mechanize in Python?
body: <p>I'm trying to login in and get URL from upcoming page :</p>
  
  <pre><code>br = mechanize.Browser()
  url = "http://www.blahblah.com/login-page/"
  br.open( url )
  
  br.select_form(nr = 1)
  br.form['username'] = "Foo"
  br.form['password'] = "fooPswRd"
  br.submit()
  </code></pre>
