The following generates a 2d list from a 1d list where each sub list has as many random numbers as the corresponding element in the 1d list, l.

import random
l = [4, 10, 15]
[[random.random()]*n for n in l]

Which, gives the following pretty-printed output:

[
  [
    0.9471464389026101,
    0.9471464389026101,
    0.9471464389026101,
    0.9471464389026101
  ],
  [

    0.7127486495769667,

import random

array = [4, 10, 15]

result = [[random.randint(YOUR_MIN_NUMBER, YOUR_MAX_NUMBER) for _ in range(i)] for i in array]

Output:

[[4, 4, 5, 3], [7, 7, 7, 6, 3, 6, 3, 6, 8, 9], [6, 3, 6, 4, 1, 3, 5, 10, 3, 10, 7, 9, 1, 3, 1]]
