  <p>That is happening all the time. Thanks for any help.</p>
  
  <p><strong>Update</strong>:<br>
  I find that installing Python 2.* makes it okay, cause of <code>main</code> module isn't correct while using <code>print</code> (Using 2.* version).<br>
  But i still want to know, it there any ways?</p>
