<p>the error i get is this  Non-ASCII character '\xc2' in file race1.py on line 13, but no encoding declared; see <a href="http://www.python.org/peps/pep-0263.html" rel="nofollow">http://www.python.org/peps/pep-0263.html</a> for details</p>

<p>Not able to understand what the error is and how to get rid of it?</p>
