From Python to 100, we're going to divide it into 10 units and give each section a chance to pick 5

Help on method choices in module random:

choices(population, weights=None, *, cum_weights=None, k=1) method of random.Random instance
    Return a k sized list of population elements chosen with replacement.

    If the relative weights or cumulative weights are not specified,
    the selections are made with equal probability.

>>> sample = random.choice (range (1, 101), weights = weighted, k=10000)
>>> sample

>>> from collections import Counter
>>> c = Counter(sample)
>>> for k, v in sorted(c.items()):
    print(k, v)
