Python Object with @property's to dict -

i'm new python please excuse if i've glazed on simple this.

i have object this:

class myobject(object):     def __init__(self):         self.attr1 = none         self.attr2 = none      @property     def prop1(self):         return foo.some_func(self.attr1) 

and instantiate this:

a = myobject() a.attr1 = 'apple' a.attr2 = 'banana' 

and method it's wrapped in expects return of dict, this:

return a.__dict__ 

but prop1 not included in return. understand why is, it's not in object's __dict__ because holds real attributes.

so question is, how can make return, return this:

{'attr1': 'apple', 'attr2': 'banana', 'prop1': 'modifiedapple'} 

other right before return doing:

a.prop1_1 = a.prop1 

you should leave __dict__ be, use attributes live directly on instance.

if need produce dictionary attribute names , values includes property, add property or method produces new dicitonary:

@property def all_attributes(self):     return dict(vars(self), prop1=self.prop1) 

this automated introspection detect property objects, take account use properties avoid having calculation up-front in first place; triggering calculations properties may not desirable.
