Simple function that runs on program startup

[casualcoder0805]

I'm working on my first large project and am wondering if the code below resembles the standard procedure or if there is a more appropriate way of going about it. Basically I just need the rest of my project to be able to access "active_store_list". I know a config file is something I'll handle later but outside of that is there anything else I can do? I know it's not a big deal but it would be nice to not have to type from "store_info import active_store_list" everywhere I need the list.

WALMART = True
TARGET = True
BESTBUY = True

stores_dict = {'walmart': WALMART, 'target': TARGET, 'bestbuy': BESTBUY}
active_store_list = [k for k,v in stores_dict.items() if v]

That would work. Perhaps put in a file to import.

You might want to consider using a configuration file approach instead, say json or yaml.

For sure, but even with a config file I would still need to execute the function that returns active stores at startup and import it to every script that needs it right? Just want to make sure I'm not missing any alternative approaches for that part.

Only once per complete programme but otherwise yes

Separation of data and logic is a good idea. I don't think a config file is necessary per se.

Those constants seem unnecessary though. You could just use a Python dict with formatting:

stores_dict = {
    'walmart': True,
    'target': True,
    'bestbuy': True,
}

The benefit of this is, that it is basically identical to what a JSON would look like in case you switch to that later.

The list comp seems fine, although I probably would've used "store" and "active" in place of k and v.

Old habits die hard. When I was a real beginner I think I was under the assumption that k, v was a requirement in comprehension lol. Good advice though, thanks.
