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

You can combine advantages of dict and class together, using some wrapper class inherited from dict. You do not need to write boilerplate code, and at the same time can use dot notation.

class ObjDict(dict):
    def __getattr__(self,attr):
        return self[attr]
    def __setattr__(self,attr,value):
        self[attr]=value

self.group = ObjDict(a=1, b=2, c=3)
print self.group.a
