Getting Python System Calls as string results
<p>I'd like to use <code>os.system("md5sum myFile")</code> and have the result returned from os.system instead of just runned in a subshell where it's echoed.</p>

<p>In short I'd like to do this:</p>

<pre><code>resultMD5 = os.system("md5sum myFile")
</code></pre>

<p>And only have the md5sum in resultMD5 and not echoed.</p>
