Your nested dictionnary is a completely separate dict, and you can get its own keys with its own keys() method : If you want to recursively get all the keys inside nested dictionnaries, you will have to implement a method for that : you're asking python "What keys exist in the data corresponding to key '2'? In this, we perform required recursion for inner nestings, and isinstance is used to differentiate between dict instance and other data types to test for nesting. Then we print the people[4], to see that the dictionary 4 is added in nested dictionary people. It's just a code dump with some text added as a kind of justification.
