Timify routine for Python3

Takes a number of seconds i.e. “120000002” and converts into “3y 42w 2d 21h 20m 2s”.

function timify(int $seconds):string
{
    $units['s'] = 1;
    $units['m'] = 60;
    $units['h'] = 60 * $units['m'];
    $units['d'] = 24 * $units['h'];
    $units['w'] = 7 * $units['d'];
    $units['y'] = 52 * $units['w'];

    $result = [];

    foreach (array_reverse($units) as $unit=>$value)
        if (($s = floor($seconds / $units[$unit])) != 0)
        {
            $result[] = $s.$unit;
            $seconds = $seconds - $s * $value;
        }

    return implode(" ",$result);
}
