How to dynamically access class properties in Python?

Question

Let\'s say I create an instance of a class and want to assign some values to its public properties. Usually, this would be done like this:

class MyClass:

After reading rejected Syntax For Dynamic Attribute Access I'm using a mixin class providing dictionary-style access to an object's attributes :

class MyClass:
    def __init__(self):
        self.name = None
        self.text = None
    def __getitem__(self, name):
        return getattr(self, name)
    def __setitem__(self, name, value):
        return setattr(self, name, value)
    def __delitem__(self, name):
        return delattr(self, name)
    def __contains__(self, name):
        return hasattr(self, name)

While still being able to set attributes directly:

myclass = MyClass()
myclass.name = "foo"
myclass.text = "bar"

it's then possible to set them dynamically :

for attr in ('name', 'text'):
    myclass[attr] = confirm(attr, default=myclass[attr])
