Develop a python program to simulate traffic lights. This needs to implement one sequence of blinking LEDs as follows:RED ON indicating stop (1 second)RED ON, YELLOW on indicating attention(1 second)GREEN ON indicating go (1 second)PAUSE(3 seconds)GREEN ON, YELLOW blinkingindicating attention(3 times)RED ONindicating stop(1 second)Use time.sleep()method to holdand blink the LEDs. Use whileloop to repeat the sequence
