Question

I make a minimised DFA, to use key value style coding, I used dictionary.

so there is a dictionary,

{1: {1:2}}

I want to update this dictionary add 2:3 to add key 1’s dictionary.

{1: {1:2, 2:3}}

I don’t know how to do this.

Is any simple idea to solve this?

Answer 1

you can use update():

In [27]: dic={1: {1:2}}

In [28]: dic[1].update({2:3})

In [29]: dic
Out[29]: {1: {1: 2, 2: 3}}
