I want to add a function in my web app. when user click such new function, the backend view.py will call and run another python program (new_function.py). this new_function.py noramally needs to run at least 200 - 300 seconds in real time. Since my account only gets 2000 cpu seconds, it will very soon reach the limit. I am wondering if it is true? what's the difference between 2000 cpu seconds and new_function.py execution time (200-300 seconds). If I deploy such function in my web app, appromately how many times can users run it per day? during the runing of this new_funciton.py, does it affect other users to browse the website?
