Understanding Python Data Structures: Lists, Tuples, Sets, and Dictionaries
Education / by Nanditha Mahesh / 49 views
Introduction
Python provides several built-in data structures that help in organizing and managing data efficiently. The four primary data structures in Python are Lists, Tuples, Sets, and Dictionaries. Each of these has unique properties and use cases.Absolutely! Let’s break down Python’s core data structures: lists, tuples, sets, and dictionaries. Python Course in Bangalore Understanding these is fundamental to writing effective Python code.
Lists: Ordered, Mutable Collections
Definition: Lists are ordered sequences of items. They can hold elements of different data types (integers, strings, other lists, etc.).
Mutability: Lists are mutable, meaning you can change their contents after creation (add, remove, or modify elements).Python Training in Bangalore
Syntax: Created using square brackets [] with comma-separated elements
The four fundamental data structures in Python are:
Lists – Ordered, mutable collections of elements.
Tuples – Ordered, immutable sequences of elements.
Sets – Unordered collections of unique elements.
Dictionaries – Unordered collections of key-value pairs.
Lists – Ordered, Mutable Collections of Elements
A list in Python is a versatile data structure that allows you to store multiple items in a single variable. Best Python Course in Bangalore Lists are ordered, meaning elements maintain their sequence, and they are mutable, meaning you can modify their contents. Lists can contain elements of different data types, such as integers, strings, floats, or even other lists.
Key Features of Lists:
✅ Ordered – Elements have a fixed position in the list.
✅ Mutable – Elements can be changed, added, or removed.
✅ Allows Duplicates – Multiple occurrences of the same value are permitted.
✅ Heterogeneous – Can store different data types in the same list.
Tuples – Ordered, Immutable Sequences of Elements
A tuple in Python is a collection that is ordered but immutable, meaning its elements cannot be changed after creation.Top Python Training in Bangalore Tuples are often used for storing data that should remain constant throughout the program.
Key Features of Tuples:
✅ Ordered – Elements maintain their sequence.
✅ Immutable – Cannot be changed, added to, or removed after creation.
✅ Allows Duplicates – Can contain repeated values.
✅ Heterogeneous – Can store different data types.
Sets – Unordered Collections of Unique Elements
A set in Python is a collection that contains only unique elements and is unordered, meaning there is no defined order for its elements. Sets are useful when you need to store distinct values and perform mathematical operations like union, intersection, and difference.Python Training in Bangalore
