Importing global namespace in python

Question

let\'s say i have the following files:

a.py

glo_var = 0
def func():
    global glo_var
    glo_var = 5
    print \"A %d\" % (glo_var)

Answer 1

Using from ... import ... copies the references from the other module. Rebinding the value in the original causes it to have a new reference, breaking the link between a.glo_var and b.glo_var permanently. Either use a mutable object and mutate it, or reimport a.glo_var whenever you need the updated value.
