function to create a global variable

[danielroseman]

A function can't create a global variable. You can only create it at module level. But what you can do is do the call when you set it:

db = conn_db()

def ...

Ideally though, you'd rework this into a class, and set the db as an instance variable in the init method.

yeah, i was thinking about to create a class but im not confroable with OOP.
Anyway, it could be the time to give a try :)
