I use a 'SuperDict' all the time in my code. Not sure it's a good idea, but
I find it convenient. Also, I wouldn't mind comments on why/why not to use
something like this:
class SuperDict(dict):
def __getattr__(self, attr):
return self[attr]
def __setattr__(self, attr, value):
self[attr] = value
def set_with_dict(self,D):
""" set attributes with a dict """
for k in D.keys():
self.__setattr__(k,D[k])
Here's the original thread (NOTE: I have also been trying to use more
structured arrays as recommended by one poster):
