Creating 2D dictionary in Python

Creating 2D dictionary in Python

It would have the following syntax

dict_names = {
    d1: {
        name: bob,
        place: lawn,
        animal: man
    },
    d2: {
        name: spot,
        place: bed,
        animal: dog
    }
}

You can then look things up like

>>> dict_names[d1][name]
bob

To assign a new inner dict

dict_names[d1] = {name: bob, place: lawn, animal: man}

To assign a specific value to an inner dict

dict_names[d1][name] = fred

Something like this would work:

set1 = {
     name: Michael,
     place: London,
     ...
     }
# same for set2

d = dict()
d[set1] = set1
d[set2] = set2

Then you can do:

d[set1][name]

etc. It is better to think about it as a nested structure (instead of a 2D matrix):

{
 set1: {
         name: Michael,
         place: London,
         ...
         }
 set2: {
         name: Michael,
         place: London,
         ...
         }
}

Take a look here for an easy way to visualize nested dictionaries.

Creating 2D dictionary in Python

Something like this should work.

dictionary = dict()
dictionary[1] = dict()
dictionary[1][1] = 3
print(dictionary[1][1])

You can extend it to higher dimensions as well.
