Syntax: Dictionaries

Python Dictionaries

Python's dictionaries are a crucial data structure that allow pairing of keys with values, making it efficient to organize and retrieve information.

Creating Dictionaries in Python

A dictionary in Python is defined using curly brackets ({}). Inside these brackets, keys and values are declared in pairs using a colon (:).

user = {
  "name": "Bob",
  "email": "[email protected]",
  "age": 35
}
print(user)

> {'name': 'Bob', 'email': '[email protected]', 'age': 35}

In the code above, we have created a dictionary user which has three keys: "name", "email", and "age". Each key has an associated value.

Practice: Creating a Dictionary

1. Create a dictionary named book with the keys "title", "author", and "year". Assign appropriate values to each key.

2. Print the book dictionary.

> {'title': '1984', 'author': 'George Orwell', 'year': 1949}

book = {
  "title": "1984",
  "author": "George Orwell",
  "year": 1949
}
print(book)

Fantastic! You've now grasped the fundamental concept of creating dictionaries in Python. In future lessons, we will explore how to access, modify, and perform various operations on these dictionaries.
