How does an average product handle initialization in python?
I am facing lot of issues in handling initialization, especially if I
import specific variables, due to the variables not getting updated.
For example - taking a sqlalchemy based product:
Module database:
^^^^^^^^^^^^^^^^^^^
Session = None
def init(dbname):
engine = create_engine('sqlite:///%s' %dbname)
...
global Session
Session = sessionmaker(bind=engine)
In entry module to the application (APPENTRY):
^^^^^^^^^^^^^^^^^^^
import A, B, C, D <---- Please note, very important
....
....
database.init('testdb.db')
Now in user module A:
^^^^^^^^^^^^^^^^^^^^^^^^^^
from database import Session
print Session
--->This will print None, because at APPENTRY, during importing A
itself, Session is stored.
I have to call database.Session to get the values.
Why is the variable not getting updated? Can anyone help me out?
