During the final weeks of my exam session I started reading a bit about python 3 using an excellent book: [Dive into Python](http://www.diveintopython.net/).
|
||
|
|
When I noted that python uses the [Mersenne Twister PRNG](https://en.wikipedia.org/wiki/Mersenne_Twister) as well I decided to write another version of my [Buridan's donkey program](http://francescomecca.eu/index.php/archives/207).
|
||
|
|
|
||
|
|
{% highlight python %}
|
||
|
|
import random, sys
|
||
|
|
|
||
|
|
if __name__ == '__main__':
|
||
|
|
args = list()
|
||
|
|
if not sys.stdin.isatty():
|
||
|
|
for line in sys.stdin:
|
||
|
|
if line[-1] is '\n':
|
||
|
|
line = line[:-1]
|
||
|
|
args.append(line)
|
||
|
|
else:
|
||
|
|
args = sys.argv[1:]
|
||
|
|
argRange = len(args)
|
||
|
|
for i in range(argRange):
|
||
|
|
print(str(i+1) + '.', args.pop(random.randrange(0, len(args))))
|
||
|
|
{% endhighlight %}
|
||
|
|
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.
|
||
|
|
|
||
|
|
Not satisfied enough, I wrote also a telegram bot using the [telebot library](https://github.com/eternnoir/pyTelegramBotAPI) that works as the script above but inside the telegram app.
|
||
|
|
The bot can be added to your contact list by simply searching for [@duridan\_donkey\_bot](http://telegram.me/duridan_donkey_bot) (yes, a typo!)
|
||
|
|
|
||
|
|
All the code is opensource and can be found on my github page.
