input: Write a function to generate an even number between 10 and 200 that is divisible by 5. If the given number does not meet the condition, the function should increment the number and check again until it finds a valid number.
  assert generate_even_number()==70
  assert generate_even_number()==90
  assert generate_even_number()==100
  assert generate_even_number()==110
  assert generate_even_number()==120
output: def generate_even_number():

      while True:
          if num % 2 == 0 and num % 5 == 0:
              return num
          num += 1
          if num > 200:
              num = 10
