I'm having a conceptual mind-fart today. I just modified a bunch of code to use
"from xx import variable" when variable is a global in xx.py. But, when I
change/read 'variable' it doesn't appear to change. I've written a bit of code
to show the problem:
mod1.py
myvar = 99
def setvar(x):
global myvar
myvar = x
test1.py
import mod1
mod1.myvar = 44
print (mod1.myvar)
mod1.setvar(33)
print (mod1.myvar)
If this test1.py is run myvar is fine. But, if I run:
test2.py
from mod1 import myvar, setvar
myvar = 44
print (myvar)
setvar(33)
print (myvar)
It doesn't print the '33'.
I thought (apparently incorrectly) that import as would import the name myvar
into the current module's namespace where it could be read by functions in the
module????
