Python Tuple Methods

INTERACTIVE CHEAT SHEET

The Concept

Because tuples in Python are immutable (meaning they cannot be changed after creation), they lack the extensive modification methods that lists have, such as `append()`, `remove()`, or `insert()`. Python provides only two built-in methods for tuples, strictly designed for searching: `count()` and `index()`.

Key Points

.count(value): Searches the tuple and returns the number of times a specified value appears.
.index(value): Finds the first occurrence of the specified value and returns its index position.
Using methods that modify an object (like .append) will raise an AttributeError on a tuple.
