render_template in Flask only seems to work when it's done at the end of a function, eg return render_template('index.html'). I have a long function where I want to update a webpage several times to keep the user updated with the progress. Should this just be split into several functions with each one rendering a new page?

3There is a misconception in your thought. This responsibility is not from Flask, but from the front (browser). Take a look at Flask + AJAX examples. – Mauro Baraldi Aug 22 '18 at 10:25
