Python random numbers in Jupyter

For many analyses, we are interested in calculating repeatable results. However, a lot of analysis relies on random numbers being used. In Python, you can set the seed for the random number generator to achieve repeatable results with the random_seed() function.

In this example, we simulate rolling a pair of dice and looking at the outcome.

The script we are using is this:

import pylab
import random
random.seed(113)
samples = 1000
dice = []
for i in range(samples):
    total = random.randint(1,6) + random.randint(1,6)
    dice.append(total)
pylab.hist(dice, bins= pylab.arange(1.5,12.6,1.0))
pylab.show()

Once we have the script in Jupyter and execute it, we have this result:

I had added some more statistics. I'm not sure ...
