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' 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 >
