input: Write a function to generate a list of random numbers of a given length.
  assert generate_random_numbers(5) != generate_random_numbers(5)
  assert len(generate_random_numbers(10)) == 10
  assert all(isinstance(num, int) for num in generate_random_numbers(7))
output: import random
  
  def generate_random_numbers(length):
      return [random.randint(0, 100) for _ in range(length)]
