input: Write a python function to generate a list of n random numbers between 1 and 100 and return their sum.
  assert sum_of_random_list(10) >= 10 and sum_of_random_list(10) <= 1000
  assert sum_of_random_list(5) >= 5 and sum_of_random_list(5) <= 500
  assert sum_of_random_list(15) >= 15 and sum_of_random_list(15) <= 1500
output: import random
  
  def sum_of_random_list(n):
      random_list = [random.randint(1, 100) for _ in range(n)]
      return sum(random_list)
