where are the "class variables"?

[Dominik Kaspar]

i'm used to java and its strict way of defining variables. so how is
it possible to reach something like a class variable in python?
with the following code i didn't have much succes...

class Server(threading.Thread):
running = 0 (??)

def run(self):
running = 1
while running:
print "do something here..."

def exit(self):
running = 0

thanks

This is where self is for: self.running refers to the class
variable 'running'.

This is correct - it binds 0 to the identifier running in the class.

def run(self):
running = 1
use Server.running
while running:
use while Server.running: print "do something here..."

def exit(self):
running = 0
use Server.running

If you want to put an identifier in the class, reference the
class directly, or inherit from object and use a class method.

Try:

class Server(threading.Thread):
running = 0
def run(self):
Server.running = 1
while Server.running:
print "Hello!"
self.exit()
def exit(self):
Server.running = 0

If you want class /functions/, though, you need a recent version of
Python.

Gerrit, I'm afraid you answsered too fast. here, 'self.running' will
refer to (and eventually create) an *instance* variable 'running'. If
the OP want a *class* variable, he needs 'Server.running'.

(Now does the OP really want a class variable or did he meant an
instance variable is another question...)

Access class members... as members of the class! :)

class Server(threading.Thread):
running = 0

def run(self):
Server.running = 1 # note added "Server."
while Server.running: # ditto, added "Server."
print "do something here..."

def exit(self):
Server.running = 0 # ditto, added "Server."

TTFN,
Tom.

Sorry, this should be:
self.__class__.running

prefix running with the class name:
Server.running =1
while Server.running:
...
Server.running = 0
