Python Dictionaries

A dictionary in Python is an ordered collection used to store data in key-value pairs. It’s perfect when you need to label your data for clarity — just like fields in a form.

What is a Dictionary?

Each item in a dictionary is written as:

key : value
Items are separated by commas.
The entire dictionary is enclosed in {}.

Example :

				
					student = {
    "name": "Hassan",
    "age": 20,
    "isEnrolled": True
}
print(student)

Output:

				
					{'name': 'Hassan', 'age': 20, 'isEnrolled': True}

Here:

"name" is a key and "Hassan" is its value.
"age" has the value 20.
"isEnrolled" has the boolean value True.

Key Features

Keys are unique.
Values can be of any data type — string, number, boolean, list, even another dictionary!
You can access, modify, add, or remove items easily.

Summary

Use {} to create a dictionary.
Store values as key-value pairs.
Great for structured data like a person’s profile, student records, or configurations.
