The line
> result = someFuntion(default = value)
is executed when the whole 'class' compound statement is executed,
i.e.
before the line that creates the 'dummy' instance. Moreover, this
happens only once and not every time you create a new instance of
the class. If you want 'result' to be a class attribute that is set
every time you create a new instance move the line
> result = someFuntion(default = value)
in the __init__ constructor (you also have to assign some value to it
before,
just like the 'value' attribute and preffix it with Dummy. otherwise
it'll
be considered as local name of __init__):
class Dummy():
value = 0
result = 0
def __init__(self, thisValue):
print thisValue
self.value = thisValue
Dummy.value = thisValue
Dummy.result = someFuntion(default = Dummy.value)
def testing(self):
