Dear all,
I have a very simple module
glic3 at e4200:# cat globalstate.py
GLOBAL = 0
def update():
GLOBAL += 1
however it doesn't work!!
glic3 at e4200:# python
Python 2.7.3 (default, Aug 1 2012, 05:14:39)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import globalstate
>>> globalstate.update()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "globalstate.py", line 4, in update
GLOBAL += 1
UnboundLocalError: local variable 'GLOBAL' referenced before assignment
And I don't know why :(
Anyone ?
Thanks!!
