Challenge: Traffic lights

Task

Task Description: Write a Python program that simulates a traffic light using a generator. The program should display the state of the traffic light ("Red", "Yellow", "Green") for a specified number of cycles.

Task Conditions:

Write a generator traffic_light_generator that yields the state of the traffic light ("Red", "Yellow", "Green") in an infinite loop.
Use this generator to output the state of the traffic light to the console nine times in the program.

Example Output:

Note that the program should use the generator to create the sequence of traffic light states, and the output should occur within the specified number of cycles.
