Using variables from my main module in my imported modules.

[GIJosh]

Hi guys. I'm new to python, so go easy.
Heres my problem. I've got my main file, Python Paint.py

#Python Paint.py
from graphics import *
import time
import functions
 
win = GraphWin("Python Paint",600,600)
win.setCoords(-100.0,-100.0,100.0,100.0)
mycolor = "red"
center = Point(0,95)
 
functions.tri()
 
as you can see, I import another file I've written, called functions.py
here it is:
 
#functions.py
from graphics import *
import time
 
def tri():
    direc = Text(center, "Click three points to form a triangle")
    direc.draw(win)
    time.sleep(2)
    direc.undraw()
    click1 = win.getMouse()
    click2 = win.getMouse()
    click3 = win.getMouse()
    triang = Polygon(click1,click2,click3)
    triang.setFill(mycolor)
    triang.draw(win)
tri()

I assign variables in my Python Paint file, but when i try to call these variables in my functions file, I get an error. Is there any way I can use variables from my main file in my functions file? I hope I've explained this properly.

Pass what you need in the parameters.
That last part eliminates import problems and allows you to test the module.

I still get this error when I try that:

NameError: name 'win' is not defined

That can happen if you are trying to run in an interactive window using "import".
If you are using

>>> import themodule

The try

>>> reload(themodule)

Then we'll discuss better way to run your programs.

Or perhaps, simply post your modified code here (instructions for using CODE tags are on the right hand side of the page).
