Today we are going to dive deep 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'
}

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'
  }
}

Easy to understand?💡

A dictionary contains

unique keys
a 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
