I couldn't really catch your explanation, but mention of changing all
instances of a class suggests that you may be in a situation where you
need to modify the class, not its instances. There are two methods I use
when I have to change things across all instances:
def A(object):
"A class that provides a variable shared by all instances,
and a method of changing it using a normal method and, for
example's sake, a class method."""
class_level_variable = True
def __init__(self):
pass
def getvalue(self):
return self.class_level_variable
def setvalue(self, newval):
self.__class__.class_level_variable = newval
def setvaluecls(cls, newval):
cls.class_level_variable = newval
setvaluecls = classmethod(setvaluecls)
sevaluecls and setvalue look the same to callers calling them on an
instance of the class.
I have no idea if that's actually appropriate for your needs, it's just
a stab in the dark, but perhaps it might be.
