Question

I have a following dictionary:

d = {'key':{'key2':[]}}

Is there any way to append to d[‘key’]?

I want to get:

d = {'key':{'key2':[], 'key3':[]}}

d[‘key’] = [‘key3’] apparently does not produce the desired outcome..

I know I can do

d = {'key': [{'key2': []}]}

and then append to d[‘key’] in a loop, but I am trying to avoid that..

Answer 1

You’re looking for

d['key']['key3'] = []
