If you need to hold "state" information, you need to store it somewhere else (like in the session, or on the filesystem, or in a database). In other words, this would be the WRONG way to do things class Foo: def doFirstThing(self): self.firstThingDone = true def doSecondThing(self): if not self.firstThingDone: raise Exception else: # do real work Because when the call comes in to doSecondThing(), you can't count on getting the same instance of Foo that you got when you called doFirstThing(). >_______________________________________________ >Mod_python mailing list >Mod_python at modpython.org >http://mailman.modpython.org/mailman/listinfo/mod_python > > >
