How to create inline objects with properties?

Question

In Javascript it would be:

var newObject = { \'propertyName\' : \'propertyValue\' };
newObject.propertyName;  // retur         


        

Answer 1

Python 3.3 added the SimpleNamespace class for that exact purpose:

>>> from types import SimpleNamespace

>>> obj = SimpleNamespace(propertyName='propertyValue')
>>> obj
namespace(propertyName='propertyValue')

>>> obj.propertyName
'propertyValue'

In addition to the appropriate constructor to build the object, SimpleNamespace defines __repr__ and __eq__ (documented in 3.4) to behave as expected.
