Looks a good idea. I use this kind of "recursive dicts" to represent
tree like datastruct in python. Like:
car["ford"]["taurus"]["price"]=...
car["toyota"]["corolla"]["mpg"]=...
car["toyota"]["corolla"]["price"]=...
It would be good if it could be combined with class2dict (converting
dict elem
That's a very nice suggestion. Thanks.

Why do that anyway? You can use a tuple as a subscript:
d[1,'abc',40]

Follow the link to the cookbook and read Andrew Dalke's comment ;)
To spell it out:
>>> class D(dict):
... def __missing_
I found a solution here:

Please tell how good is it?

I can extend dictionary to allow for the my own special look-up tables. However
now I want to be able to define multidimensional dictionary which supports
look-up like this:
d[1]['abc'][40] = 'dummy'
and if d[1] and d[1][abc] raise KeyError just create them.
for d[1] I can override __getitem__
10 matches
