>>> VAR = "TEST"
>>> def m():
	global VAR              ## <- this is what you were missing . . .
basically, this means
	VAR = "no test"       ## that, instead of assigning to a new variable
VAR in the local
                                      ## namespace of m(), you are
assigning to the variable VAR that
                                      ## was defined on the global level

	
>>> print VAR
TEST
>>> m()
>>> print VAR
no test
