I have another question when the program runs it presses the w key on the keyboard constantly, but I want it to only run for a few seconds then pause then run again until I press ctrl+c to stop the program.

I have my new code but still i do not know how to stop the program when its running by pressing the q button?

Did you look at the example for monitoring the keyboard?
