+summary: Quick and dirty way to convert a dict into an object in Python using namedtuple's
+
+A friend shared this with me today and I thought it was pretty neat.  If you have a dict, and
+you want to convert it to an object where the object properties are the keys from the dict, and
+the values are the values from the dict, you can use a namedtuple to do so.  For example:
+
+```python
+>>> some_dict = {"name": "My name", "func" : "my func"}
+>>> import namedtuple
+>>> SomeClass = namedtuple("SomeClass", some_dict.keys())
+>>> as_an_object = SomeClass(**some_dict)
+>>> as_an_object.name
+'My name'
+>>> as_an_object.func
+'my func'
+```
+
+Won't handle nested dicts (the sub-dicts will still be dicts on the constructed object), but
+for a quick and dirty way to convert a dict to an object, this seems pretty handy.
+
+Using the splat operator you can also save a line of code:
+
+```python
+>>> as_an_object = namedtuple("SomeClass", some_dict.keys())(**some_dict)
+>>> as_an_object
+SomeClass(name='My name', func='my func')
+```
