[LUG] Global variables in Python?

[Grant Phillips-Sewell <dcglug@xxxxxxxxxxxxxxxxxxxxx>]

Hi all,

Having a bit of a problem with getting my head around how Python handles global variables.

Here's an example snippet of code:

----Python Code----

#!/usr/bin/env python

global SOMEVAR

SOMEVAR = "Hello"

def FNsomefunction():

  SOMEVAR = "Goodbye"

print SOMEVAR

FNsomefunction()

print SOMEVAR

----End of Python Code----

When this is run, the output is Hello twice.

Now, to my brain since SOMEVAR is a global variable, the contents should be accessible from any part of the code, and should be changeable from any part of the code too.

Am I thinking about, or implementing this in completely the wrong way?

Cheers.

Grant. :)
