How to run a script using Django?

So I've conntected GMail API to my Django project. When I run quickstart.py alone in PyCharm it runs and works perfectly (that's the script that opens a new tab with GMail log in).

Great but now I have to give a user an opportunity to do the same. So I decided that I'll create a button and with pressing that button the quickstart.py will run and user will log in. I tried that by creating an action. Then I tried a usual 'a' tag. And in both cases was error "Not found". Also I even tried to run an php where I execute .py script.Sounds crazy.

    <?php
echo exec('/quickstart.py');
?>

But the error is the same. I've also tried to play with url.py and write paths. I think I don't understand something. Please, explain.

So again and shortly: Press button -> Run quickstart.py
