Learn Python #9 – Yeah Dictionary🐍

  • 60k

Today we are going to deep dive into the main data structure in Python known as Dictionary.

Not a dictionary of words

What is Dictionary?💡

In Python, a dictionary is a list of key-value pairs.
Ok, let's take an example.

Creating a Dictionary💡 

dictionary_1 = {   'name': 'Nitin',   'age': 34,   'country': 'India' }
Enter fullscreen mode Exit fullscreen mode

In the above example
name, age, and country are the keys with the corresponding values as Nitin, 34, and India.

Also, we can create a nested dictionary 

dictionary_1 = {   'name': 'Nitin',   'age': 34,   'address': {     'street': 'Keshav'     'country': 'India'   } }
Enter fullscreen mode Exit fullscreen mode

Easy to understand?💡

A dictionary contains

  • unique keys
  • key can have different types of values like number, string, boolean etc.

This would look similar to an object in JavaScript

Accessing a key's value💡 

dictionary_1 = {   'name': 'Nitin',   'age': 34,   'country': 'India' }  dictionary_1['name'] // Nitin   dictionary_2 = {   'name': 'Nitin',   'age': 34,   'address': {     'street': 'Keshav'     'country': 'India'   } }  dictionary_2['address']['street'] // Keshav
Enter fullscreen mode Exit fullscreen mode

To access any value in a dictionary, we need to enclose the key in square brackets []
