pythonproperties

In a Python object, how can I see a list of properties that have been defined with the @property decorator?

I can see first-class member variables using self.__dict__, but I'd like also to see a dictionary of properties, as defined with the @property decorator. How can I do this?

Solution

  • You could add a function to your class that looks something like this:

    def properties(self):
    # class_items = self.__class__.__dict__.iteritems()  # Python 2
    class_items = self.__class__.__dict__.items()
    return dict((k, getattr(self, k)) 
                for k, v in class_items 
                if isinstance(v, property))

    This looks for any properties in the class and then creates a dictionary with an entry for each property with the current instance's value.
