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