Question

OK I am doing some threading, and I guess when I started doing threading I assumed you can’t return values like a definition (its the end of the day and my brain is about to die so maybe this is incorrect and I should start going back to get rid of global variables)

Anyway I have a test program to figure out why I can’t modularize my code

a file called config.py

a_variable=0

a file called test_for_sean.py

from config import *
def blah():
  global a_variable
  a_variable=14
  return 0

a file called main.py

from config import *
from test_for_sean import *
print a_variable #this prints correctly
blah()
print a_variable #this is still printing 0....

someone link me to something so I don’t kill myself

Answer 1

Try these changes,

config.py,

a_variable = 0

tfs.py (was test_for_sean),

import config

def blah():
    config.a_variable = 14
    return 0

main.py,

import tfs, config

print config.a_variable
tfs.blah()
print config.a_variable

We still import everything from config, but are ‘global’ variables stay in their own modules. This way we can have global variables but still let main.py define its own a_variable if it needs to.
