title: Python-requests: Where to find all possible attributes?
body: <p>I was using <a href="http://docs.python-requests.org/" rel="nofollow">python-requests</a> in conjunction with a lambda function (correct me if you call it something else) to GET a url. Given that the url varied according to the value of <code>epoch()</code>, I wanted to print it for debugging.</p>
  
  <p>Lucky for me, <code>print(kiwi.url)</code> works, because <code>kiwi.url</code> exists, but for future reference, how can I find all possible attributes for python-requests, or even other modules, without relying on luck?</p>
  
  <pre><code>import time, requests
  epoch = lambda: int(time.time()*1000)
  kiwi = s.get('http://www.example.com/api?do=%i' % epoch())
  print(kiwi.url) #I found the .url attribute by chance.
             ^
