I’m working on a flask app. There is the app.py file which uses an imported variable:

from other_file import rnd

def some_func:
    return rnd

and other_file.py

import random

rnd = random.randint(100000, 1000000)

On each request, the returned value of the function is different. Why?

What if I want to store some app-wide data in a variable, for example:

logged_in_users_list = []

Would that be emptied after each request too?

(Actually I use a similar approach in a FastAPI app, and the variable keeps the list fine. What makes the difference?)
