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