A nice list. I use things like the simple web server all the time, and I was unaware of the SMTP server, but some of these seem superflous, like:<p><pre><code> python -m calendar
</code></pre>
When you could just do<p><pre><code> cal 2013
</code></pre>
(with fewer keystrokes). Is there some advantage to using the python version of the above?
A lot more examples are in the Python wiki: <a href="http://wiki.python.org/moin/Powerful%20Python%20One-Liners" rel="nofollow">http://wiki.python.org/moin/Powerful%20Python%20One-Liners</a>
