<h1 class="post-title">The Buridan's donkey in python</h1>
<span class="post-date">02 Apr 2016</span>
<p>During the final weeks of my exam session I started reading a bit about python 3 using an excellent book: <a href="http://www.diveintopython.net/">Dive into Python</a>.
When I noted that python uses the <a href="https://en.wikipedia.org/wiki/Mersenne_Twister">Mersenne Twister PRNG</a> as well I decided to write another version of my <a href="http://francescomecca.eu/index.php/archives/207">Buridan&#39;s donkey program</a>.</p>

<p>This script works in a different way than the one in c++.
Rather than shuffling a list made by the entries in the arguments, it pops randomly one entry from the list till the list is empty.</p>
<p>Not satisfied enough, I wrote also a telegram bot using the <a href="https://github.com/eternnoir/pyTelegramBotAPI">telebot library</a> that works as the script above but inside the telegram app.
The bot can be added to your contact list by simply searching for <a href="http://telegram.me/duridan_donkey_bot">@duridan_donkey_bot</a> (yes, a typo!)</p>
<p>All the code is opensource and can be found on my github page.</p>
