Using a class as a data container

Question

Sometimes it makes sense to cluster related data together. I tend to do so with a dict, e.g.,

self.group = dict(a=1, b=2, c=3)
print self.group[\'a\']
         


        

Answer 1

There is a new proposal that aims to implement exactly what you are looking for, called data classes. Take a look at it.

Using a class over a dict is a matter of preference. Personally I prefer using a dict when the keys are not known a priori. (As a mapping container).

Using a class to hold data means you can provide documentation to the class attributes.

Personally, perhaps the biggest reason for me to use a class is to make use of the IDEs auto-complete feature! (technically a lame reason, but very useful in practise)
