Python strip method
<p>Today in python terminal, I tried</p>

<pre><code>a = "serviceCheck_postmaster"
a.strip("serviceCheck_")
</code></pre>

<p>But instead of getting <code>"postmaster"</code>,  I got <code>"postmast"</code>.</p>

<p>What could cause this? And how can I get <code>"postmaster"</code> as output?</p>
