title: Python regular expression syntax error
body: <p>I am trying to write a regular expression that will match a <code>-</code> (dash), followed by as many letters as it possibly can. What I have at the moment, is the following: <code>exp = (-[a-z A-z]*)</code>.<br>
  I am getting a <code>SyntaxError: invalid syntax</code> error though.</p>
