How to zero pad a sequence of integers in bash so that all have the same width?
...mat the numbers as it outputs the list. For example:
for i in $(seq -f "%05g" 10 15)

Generate random numbers with a given (numerical) distribution
...y.random.choice(), e.g.
numpy.random.choice(numpy.arange(1, 7), p=[0.1, 0.05, 0.05, 0.2, 0.4, 0.2])
If you are using Python 3.6 or above, you can use random.choices() from the standard library – see the answer by Mark Dickinson.
