I am trying to define a class static variable. But the value of the
static variable seems to be only defined inside the file that the
class is declared. See the code below. When I run "python w.py", I
got:
000=======> Hello World
001=======> Hello World
002=======> Not Initialized
003=======> Not Initialized
004=======> Not Initialized
005=======> Hello World
Looks like even though the class variable "ClassW.w_classStaticVar"
was set inside "startup()", the value never carried over to functions
in "a.py". Is this a bug in Python's static variable handling. I am
running Python 2.4.4.

#===== file: w.py ========
from a import *
class ClassW:
w_classStaticVar = "Not Initialized"
def initA(self):
print "001=======>", ClassW.w_classStaticVar
obj = ClassA()
obj.init2()
print "005=======>", ClassW.w_classStaticVar
def startup():
ClassW.w_classStaticVar = "Hello World"
wo = ClassW()
print "000=======>", ClassW.w_classStaticVar
wo.initA()
if __name__ == '__main__':
startup()
#===== file: a.py ========
from w import *
class ClassA:
def __init__(self):
print "002=======>", ClassW.w_classStaticVar
def init2(self):
print "003=======>", ClassW.w_classStaticVar
w = ClassW()
print "004=======>", ClassW.w_classStaticVar
