title: Python: download files from google drive using url
body: <p>I am trying to download files from google drive and all I have is the drive's URL.</p>
  <p>I have read about google API that talks about some <code>drive_service</code> and <code>MedioIO</code>, which also requires some credentials( mainly JSON <code>file/OAuth</code>). But I am unable to get any idea about how it is working.</p>
  <p>Also, tried <code>urllib2.urlretrieve</code>, but my case is to get files from the drive. Tried <code>wget</code> too but no use.</p>
  <p>Tried <code>PyDrive</code> library. It has good upload functions to drive but no download options.</p>
  <p>Any help will be appreciated.
  Thanks.</p>
