input: Write a function to generate an even number between 10 and 200 that is divisible by 5. If the number does not fulfill the criteria, the function should keep searching until it finds a valid number.
  def generate_even_number():
      num = random.randint(10, 200)
      if num % 2 == 0 and num % 5 == 0:
          return num
      else:
          return generate_even_number()
  assert generate_even_number() % 2 == 0
  assert generate_even_number() % 5 == 0
  assert 10 <= generate_even_number() <= 200
