input: Write a python function to generate a random number between given lower and higher limits.
  assert lower_higher_random(1, 10) in range(1, 11)
  assert lower_higher_random(5, 15) in range(5, 16)
  assert lower_higher_random(0, 0) == 0
output: import random
  
  def lower_higher_random(lower, higher):
      return random.randint(lower, higher)
