Adding multi-process
First to introduce multi-process:
problems encountered: part IDLE does not support multiprocessing module, does not call the child process.
Solution: performing multi-process .py python in cmd instructions directly to

new_process.start () instruction
there is still a small problem, open the web site, found a blank.
Adding Multithreading
In our code, introducing threading module using new_thread = threading.Thread (target = subprocess, args = (parameter 1)) (note tuple args)
new_thread.start () instruction
