title: How to use a progress bar to show python function progress in Django?
body: <p>I created a website where a user uploads videos and I process the video frame by frame with a python function. In this function, I know how many frames I've already processed. And I want to show the progress to users in a progress bar. I googled a lot, but almost all progress bars are for uploading, so how can I implement this? Thanks!</p>
