Removing redundant symbols from string
<p>Let's say I have a string like that: <code>'12,423,343.93'</code>. How to convert it to <code>float</code> in simple, effective and yet elegant way?</p>

<p>It seems I need to remove redundant commas from the string and then call <code>float()</code>, but I have no good solution for that.</p>

<p>Thanks</p>
