title: Accessing user input taken in while loop (Python)
body: <p>I want user to enter random numbers.
  I run a while loop until the user enters 0.</p>
  
  <pre><code>while input()!=0:
      print "Your number is:...??"
  </code></pre>
  
  <p>My question is:
  Are there any special variables (like $_ in Perl) using which I can access the user input?
  For example (in the above case) I want to print what the user has entered.</p>
