Working with Lists, Tuples, Sets, and Dictionaries in Python

Python offers versatile data structures to handle and manipulate collections of data: Lists, Tuples, Sets, and Dictionaries. Understanding their characteristics helps in writing efficient and clean code.

Lists are ordered, mutable collections. You can add, remove, or change items. They're ideal when the order of elements matters or you need to update data. Example:

python

fruits = ["apple", "banana", "cherry"]

fruits.append("orange")

Tuples are similar to lists but immutable. Once defined, their elements cannot be changed. Tuples are used for fixed collections and are faster than lists. Example:

python

coordinates = (10.0, 20.0)

Sets are unordered collections of unique elements. They’re useful for membership tests, removing duplicates, and performing mathematical operations like union or intersection. Example:

python

numbers = {1, 2, 3, 2}

Dictionaries (dicts) store data as key-value pairs. They’re ideal for structured data and quick lookups. Keys must be unique and immutable. Example:

python

student = {"name": "Alice", "age": 20}

student["grade"] = "A"

When to use what? Use lists for ordered and frequently changing data, tuples for fixed sets, sets for uniqueness, and dicts for labeled data.

Mastering these core data structures is essential for any Python developer. They form the foundation for data handling and efficient programming.
