Still not that clear. What do you want to see when you call
MyClass().getprops_as_dict() ?
Maybe this will give you some ideas:
>>> class MyClass:
... def __init__(self, val1, val2):
... self._var1 = val1
... self._var2 = val2
... var1 = property(lambda s: s._var1)
... var2 = property(lambda s: s._var2)
... def _var3(self):
... return self._var1 + self._var2
... var3 = property(_var3)
... def getprops_as_dict(self):
... d = dict(self.__dict__)
... return d
...
>>> m=MyClass(1,2)
Using just m.__dict__:
>>> m.getprops_as_dict()
{'_var2': 2, '_var1': 1}
The inspect module might be some help:
>>> import inspect
>>> for k, v in inspect.getmembers(m):
... print k, '=', v
...
__doc__ = None
__init__ = <bound method MyClass.__init__ of <__main__.MyClass instance at
0x008DD918>>
__module__ = __main__
_var1 = 1
_var2 = 2
_var3 = <bound method MyClass._var3 of <__main__.MyClass instance at
0x008DD918>>
getprops_as_dict = <bound method MyClass.getprops_as_dict of <__main__.MyClass
instance at 0x008DD918>>
var1 = 1
var2 = 2
var3 = 3
This inspects the class for actual properties and shows their values. It won't
print simple attributes (in m.__dict__) or attributes defined by user-defined
descriptors though:
>>> for p in dir(m.__class__):
... pp = getattr(m.__class__, p)
... if isinstance(pp, property):
... print p, '=', getattr(m, p)
...
var1 = 1
var2 = 2
var3 = 3
