Question

how would i integrate a progressbar into this code? ive actually got a progressbar in the code, i just need someone to show me how to make it work.thanks. the way i've got it now, the progressbar runs and then my code runs. I need it to work with def launch_5.

I know it works, but anyone else would think the program had crashed.', wraplength=300, justify="center")
