input: Write a python function to generate a random number between 0 and 100 that is divisible by 5.
  assert (result := genRandomFive()) % 5 == 0 and 0 <= result <= 100
  assert (result := genRandomFive()) % 5 == 0 and 0 <= result <= 100
  assert (result := genRandomFive()) % 5 == 0 and 0 <= result <= 100
output: import random
  
  def genRandomFive():
      return random.choice(range(0, 101, 5))
