In the constructor of this class, a QTimer is created and started with an interval of 1000ms (1 second). The timeout signal of the timer is connected to a method called do_something. This method uses the isActive method to check whether the timer is currently running or not. If the timer is not currently running, it is restarted and the message "Timer restarted" is printed to the console. If the timer is currently running, the message "Timer is active" is printed to the console. Package library: PySide2, a Python binding for the Qt framework.
