Thanks John,
I've yet to test it but I read a few people stating to use lambdas
variables/properties. Is it definitely the case that it will only evaluate
once?
Either way I've embarked on the mission to make methods return as
properties and have found @property decorator to fit my needs, the issue
was I was calling Object.property not ObjectI().property, However I want to
apply this functionality to all my methods and am using:
__getattribute__
def __getattribute__(self, item):
super(DateCalc, self).__getattribute__(item)
But I've run into the problem that my __init__ properties don't seem to be
initialised eg I get
self._date_actual = datetime.strptime("{Y}-{m}-{d}".format(Y=year, m=month,
d=day), self._format_global).date() TypeError: must be string, not None
Anyone have an idea about what's going on?
