Python tool to balance parentheses, quotes, and brackets
<p>Does anyone know of an already-written Python script, tool, or editor that will check for unbalanced multi-line tokens? (parentheses, quotes, {}, [], etc.)</p>

<p>I've been writing Python code in IDLE, and every so often I'll get "EOF token in multi-line statement" and start swearing, because it means that somewhere in about 200 lines of code I forgot a closing parenthesis or quote and IDLE can't tell me where.  This seems like a fairly straightforward thing, I just don't really have the time or headspace to work it out myself right now.</p>

<p>Much thanks</p>
