input: Write a function to generate a list of all numbers from 0 to 50 in Python that are divisible by both 3 and 5.
  assert generate_divisible_numbers() == [0, 15, 30, 45]
  assert generate_divisible_numbers() != [15, 30, 45]
output: def generate_divisible_numbers():
      return [i for i in range(51) if i % 3 == 0 and i % 5 == 0]
