input: Write a function to generate a random number between the given input numbers. The function should take two arguments, start and stop, which represent the range within which the random number should be generated. The function should return the generated random number.
  
  import random
  
  def random_num(start, stop):
      return random.randint(start, stop)
  
  assert random_num(0, 10)>=0 and random_num(0, 10)<=10
  assert random_num(-10, 0)>=-10 and random_num(-10, 0)<=0
  assert random_num(5, 5)==5
  assert random_num(-5, 5)>=-5 and random_num(-5, 5)<=5
  assert random_num(100, 100)==100
output: import random
  
  def random_num(start, stop):
      return random.randint(start, stop)
