input: Write a function to generate a set of unique random numbers in the range 0-10.

      while len(random_numbers) < 10:
          random_numbers.add(random.randint(0, 10))
      return random_numbers
  
  assert generate_unique_random_numbers() == {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
output: def generate_unique_random_numbers():
