input: Write a python function to generate a list of random numbers of a given length.
  assert len(generate_random_numbers(5)) == 5
  assert len(generate_random_numbers(10)) == 10
  assert isinstance(generate_random_numbers(3)[0], int)
output: import random
  
  def generate_random_numbers(length):
      return [random.randint(0, 100) for _ in range(length)]
