Tuples in Python

Tuples are ordered collections similar to lists, but with one key difference: they are immutable. Once created, you cannot change their content.

Tuples are useful when you want to ensure data stays the same, or when you need a lightweight, fast collection.

Creating Tuples

Use parentheses () – comma is what really creates a tuple.

Accessing Tuple Items

Same as lists – by index.

Immutability

You cannot modify tuples – no append, remove, or item assignment.

Packing and Unpacking

Create tuples by packing values, extract with unpacking.

Tuple Methods

Only count() and index() – because tuples are immutable.

When to Use Tuples

• Fixed data that shouldn't change (like coordinates)
• As dictionary keys (tuples are hashable)
• Returning multiple values from functions
• Lightweight records
