This is a simple library that I originally wrote as part of an interview process, but I got thinking about how I'd rewrite it with what I now know.
The interface is relatively simple, you instantiate the class, with a list of weights, and results for those weights, you then call random() to get your result.
For an example, here's an example showing the result of 2 D6 dice, and the output of the product.
So to implement this using the basic LoadedRandomNumberChooser
from loaded import LoadedRandomNumberChooser
probabilities = [1, 2, 3, 4, 5, 6, 5, 4, 3, 2, 1]
random_items = [2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
two_d6 = LoadedRandomNumberChooser(probabilities=probabilities, random_items=random_items)
results = [two_d6.random() for _ in range(1000)]
from collections import Counter
counted = Counter(results)
print(counted)You'll get results of the form
Counter({7: 146, 6: 137, 8: 126, 5: 125, 10: 101, 9: 100, 4: 85, 3: 65, 11: 62, 12: 34, 2: 19})
- LoadedRandomItemChooser - Choose from a list of items
- LoadedRandomNumberChooser - Choose from a list of numbers
- SystemLoadedRandomItemChooser - Choose from a list of items using the system's more secure random number generator
