Python and Selenium - Reboot program and reuse same browser session

Question

Scenario:

I am working an an auto whatsapp responder using whatsapp web.

I log in via chromedriver on selenium with python 3.

I run a function that does some stuff inside a while True.

Problem:

Sometimes, due to a lack of conectivity with the phone, or whatever other problems, the program just does not keep running the right way.

There are a lot of factors that might cause the whole thing to lose the right flow. I am analyzing them all and fixing them as best as I can.

Question:

I came up with the idea that maybe if I restart the whole thing every hour (or every whatever-thousands iterations) it would become more solid. As it will refind the flow no matter what happens, if I did not catch the bug yet.

Is it possible to restart the whole thing, without losing the browser session? Whatsapp web requires a QR scan, but it allows a "keep session alive in further connections" (which I do not really know how it works... if cookies or something else.)

Note: I know that a python script can be rebooted, but the bigger problem here is to reuse the browser session. Of course I am doing my research. None of what I read so far made me come with a solid solution, and that is why I ask to all the super cool brains out there.

the "other problems" will likely cause errors to occur in your python script. You should be catching them and dealing with them. — asongtoruin

@asongtoruin I am doing so. Still though, there are things that I did not catch yet or which are completely out of my control. And this would be a great add-on mode. Not to ignore everything and just reboot. But to fix as much as possible and also reboot for double trouble fixer. — Álvaro N. Franz

Whatsapp stores session in localStorage of the browser.

You can extract the localStorage and save to a file on closing of a session.

Upon instantiating a session check if this file exists, then parse the file and update localStorage with saved values before opening a URL.

I did so but still it won't grab the session. I posted new question because it now is a new question: stackoverflow.com/questions/45415178/… - Thank you.
