How to access elements of a nested dictionary in Python

In this tutorial, you will learn how to form a dictionary and access elements of a nested dictionary to change it according to the need of the user.

In Python, how can we access elements of the nested dictionary?

Syntax:

dictionary = {'key_1' : 'value_1',
'key_2' : 'value_2'}

Here, the dictionary has a key : value pair enclosed within curly brackets (“{}”).

Nested Dictionary:

Syntax:

nested_dict = { 'dictA': {'key_1' : 'value_1'},
                'dictB': {'key_2' : 'value_2'}}

Here, dictA and dictB are Nested Dictionaries.

Let’s create a Nested Dictionary:

people = {1: {'name' : 'CodeSpeedy', 'age' : '34'},
          2: {'name' : 'Yash', 'age' : '23'}}

print(people)

Output:

{1: {'name': 'CodeSpeedy', 'age': '34'}, 2: {'name': 'Yash', 'age': '23'}}

People is a nested dictionary above. People are allocated to internal dictionaries 1 and 2. which have keys and values.

Until now we learned to create how to create a Nested Dictionary now let’s see how to access Nested Dictionary’s elements.

people = {1: {'name' : 'CodeSpeedy', 'age' : '34'},
          2: {'name' : 'Yash', 'age' : '23'}}

print(people[1]['name'])
print(people[2]['age'])

Output:

CodeSpeedy
23
