I’d like to point you at the the two scripts Python: Spoonfed has been working towards during the last week. They are on Patreon, but available for free.
The scripts cycle forward (or backward) through all available cameras (see the post for details). Yes, you probably have seen this or similar functionality already, but Python: Spoonfed gives you not just the scripts, it also gives you all the needed lessons to program such scripts by yourself, and detailed explanations as to what works why, and why the $%&§ thing crashed again.
There will be more to come, so don’t miss out; with 14 spoonfed lessons in, it’s still time to join, and some more patrons wouldn’t hurt either.
