[Tutor] Feed arguments to callback(?) function

[trent shipley]

I want to take and arbitrary probability distribution function, send it
it's keyword arguments, and run it as the core of a generic dice rolling
program in Python (so it is accessible to the maximum number of
programmers),


# hackable_dice_roller
# from typing import Any, List, Tuple, Callable
from random import normalvariate, randrange, seed
# import operator


class DieRoll:
    def __init__(self,
                 die,  # a probability input function
                 transform=None, # a function to transform the result
returned by the PDF
                 **die_args):  # Keyword:Value arguments to the PDF python
function (doesn't work)
        self._die = die
        self._transform = transform
        self._die_args = die_args

    def die_roll(self):
        roll = self._die(self._die_args)  # throws error
        if self._transform is not None:
            roll = self._transform(roll)
        return roll


class IntegerDieRoll(DieRoll):
    def __init__(self,
                 transform=None,
                 sides=6,
                 bottom=1):
        super().__init__(die=randrange,  # a random module pdf
                         transform=transform,
                         start=bottom,  # say 1 on a 6 sided die
                         stop=bottom + sides,  # 1 + 6 = 7, randrange
should return value 1 to 6 inclusive
                         step=1)
        if sides <= 0:
            raise ValueError("Parameter 'die' must be at least 1")

    def die_roll(self):
        return int(super().die_roll())

if __name__ == '__main__':
    seed(0)

    integer_die_roll = IntegerDieRoll()
    print(integer_die_roll.die_roll())
