input: Write a python function to generate a list of numbers from 0 to 50 that are divisible by 3.
  assert generate_divisible_by_3() == [0, 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48]
  assert generate_divisible_by_3() != [1, 3, 5, 9, 12, 15]
output: def generate_divisible_by_3():
      return [i for i in range(51) if i % 3 == 0]
