Tuple
Introduction
Tuple is an ordered and immutable collection data structure. Ordered meaning it keeps the order of elements in which they are inserted, and immutable means that once the tuple is created it cannot change, and you cannot add or remove elements from it.
Lesson Overview
In this lesson we will cover:
- How to create tuple
- Accessing the elements in tuple
- Useful methods on tuples
Creating Tuple
A tuple is created by enclosing items in parentheses () separated by comma.
Python Sandbox
Tuples containing a single element still must contain a comma, otherwise python will read the wrong data type:

Accessing Elements
Accessing elements of the tuple is done with index, just like lists.

Useful methods
Unlike functions, as we cannot modify tuples, we don't have a lot of methods available to us, but we will list a few.
count()- returns the number of times a specified value appears in tuple.Python Sandboxindex()- returns index of the first occurrence of the element.Python Sandbox
