Declaring a multi dimensional dictionary in python

Question

I need to make a two dimensional dictionary in python. e.g. new_dic[1][2] = 5

When I make new_dic = {}, and try to insert values, I get a <

Answer 1

Here is a dictionary that contains another dictionary as the value for key 1:

>>> new_dic = {}
>>> new_dic[1] = {2:5}
>>> new_dic
{1: {2: 5}}

The problem that you had with

new_dic={}
new_dic[1][2]=5

is that new_dic[1] does not exist, so you can't add a dictionary (or anything for that matter) to it.
