How to make a dictionary to a nested dictionary

Question

I have a dictionary as follow:

d1 = {1:"Peter", 2:"Teddy"}

I want to make it to:

d1 = {1:"Peter", 2:"Teddy", 3:{"Oliver" : "Big"}}

I have tried but it doesn't work:

d1[3]["Oliver"]="Big"

if the key `1` may or may not exist with a dictionary already, and you don't want to overwrite it, but add another key to the existing dictionary already there, then use: `d1.setdefault(3, {})['Oliver'] = 'big'` — juanpa.arrivillaga, Nov 04 '22 at 18:08

You can first try

d1[3] = {}

Then

d1[3]["Oliver"]="Big"
