Convert an american style minute string into integer value | 38,519,086 | <p>I got an american format string showing seconds of an elapsed event, like <code>4,942.221s</code>. How would be the most pythonic way to convert this into an integer without parsing and removing comma. I want to get the plain seconds, which in this case would be <code>4942</code>, ms can be truncated.</p>
| 1 | 2016-07-22T05:50:48Z | 38,519,263 | <p>You could use float first and then convert to int as below</p>
