title: How to complete URL's with only domain name
body: <p>So i am calling out urls i.e. &quot;domain.xyz&quot; from a .csv file. The purpose is to use the requests module to GET/HEAD responses. Using this code as a work around to add a string.</p>
  <pre><code>     x = &quot;http://www.&quot;+str('domain.com')
       response = requests.head(x)
  </code></pre>
  <p>The problem here is not all &quot;domain.com&quot; entries in my .csv start with standard <strong>http://www.</strong>. What's the best way to complete the URL before using the requests module?</p>
  <p>p.s. I am looking for something similar to what Chromes address bar does to complete a url. For instance when we enter 'abc.com'. it completes it to &quot;http://www.abc.xyz&quot;.</p>
