Inter-module globals

[Anton81]

Hi,

I want to use globals that are immediately visible in all modules. My
attempts to use "global" haven't worked. Suggestions?

Use a module and a class variables for that. Import your module and
read/update class variables as you need them.

I think a dictionary would work here
as well as list but not strings and int's

# module1
settings = {
"release" : "1.0",
"blabla" : None,
}

# module2
import module1 as settings
print settings.settin gs["release"]
settings.settin gs["blabla"] = True


# module3
import module1 as settings
settings.settin gs["blabla"] = False

I think we could manage a little example too ;-) This one is a fictitious little game project where the user can define a custom graphics directory on the command line.

Three files: game.py, graphics.py and common.py.

The common.py file contains that class with class variables that jorge was talking about. Other modules import this as needed.

The contents of the files follow below.

So:
$ python game.py
/usr/local/mygame/data/gfx
$ python game.py --gfx-dir moo/cow
/usr/local/mygame/moo/cow
$ python game.py --gfx-dir /moo/cow
/moo/cow

Hope it helps!

main.py:
--------------------------------------------------------
#!/usr/bin/python

import sys

import graphics
from common import Settings

try:
i = sys.argv.index( '--gfx-dir')
except ValueError:
pass
else:
Settings.graphi cs_dir = sys.argv[i + 1]

print graphics.graphi cs_dir()
--------------------------------------------------------



common.py:
--------------------------------------------------------
class Settings(object ):
game_dir = '/usr/local/mygame'
graphics_dir = 'data/gfx'
--------------------------------------------------------



graphics.py:
--------------------------------------------------------
import os

from common import Settings

def graphics_dir():
return os.path.join(Se ttings.game_dir , Settings.graphi cs_dir)
--------------------------------------------------------
