How to import a package and call its global functions / to get their global variable values?
I am on the package Packages/SublimeDefaultSyntax/default_syntax.py and I want to call a global function on the package Packages/SyncedSideBar/SyncedSideBar.py to get its current state on the package SublimeDefaultSyntax. How to accomplish so?
I tried several things, but they all seen useless. I just want to know the contents within on a global variable at the other package. I am able to modify both packages and to write whatever I need to get it working.
On the other file SyncedSideBar.py I got a function like this:
def print_hello():
    print( 'print_hello' )
Currently doing:
from SyncedSideBar import print_hello
I got:
reloading plugin SublimeDefaultSyntax.default_syntax

Also doing:
import SyncedSideBar
...
    def is_visible(self):
        print_hello()
        return isNotSyncedSideBarEnabled
I got:
