You are on the right way. If you import the same module a second time in another place of your application you get access to the exact same data. That is called a "singleton". I often use such a singleton for global configuration data. > So basically I want to access the same global list in both modules, > but not re-create the list in every module since it should be restored > by the database layer once. Import your global module and just run the initalisation once. That should do it. > Thanks for any advice, I do not want to make a global manager object > that I need to pass around all the time, that would be silly.. Indeed. That would suck.
