open file in finder or explorer on linux or unix
<p>I don't have any Mac OSx or Linux machine, but I want to implement the functionality like opening an explorer from a selected file path. </p>

<p>for example </p>

<pre><code>import subprocess
subprocess.Popen('explorer "E://temp//"')
</code></pre>

<p>the above code opens windows explorer for a specified path, how to do it for Mac or Linux ?</p>
