In Python, a tuple is an ordered collection of elements, enclosed in parentheses ( ). Tuples are similar to lists, but they are immutable, meaning their values cannot be changed once they are defined. This guide will introduce you to the basics of tuples, including how to create them and some common operations you can perform on them.
Introduction to Tuples in Python
In Python, a tuple is an ordered collection of elements, enclosed in parentheses ( ). Tuples are similar to lists, but they are immutable, meaning their values cannot be changed once they are defined. This guide will introduce you to the basics of tuples, including how to create them and some common operations you can perform on them.
Creating Tuples
You can create a tuple in Python using the following methods:
1. Parentheses
Enclose the elements of the tuple in parentheses:
2. Tuple Constructor
Use the tuple() constructor to create a tuple:
Accessing Tuple Elements
You can access individual elements of a tuple using indexing, similar to lists. The indexing starts from 0 for the first element.
Tuple Functions
Tuples support various functions to perform common operations. Here are a few commonly used functions:
1. len()
The len() function returns the number of elements in a tuple:
2. count()
The count() function returns the number of occurrences of a specified element in a tuple:
3. index()
The index() function returns the index of the first occurrence of a specified element in a tuple:
Example:
Tuples are a useful data structure in Python for storing a collection of values. They are immutable, meaning they cannot be modified once created, which makes them suitable for situations where you need to store data that should not be changed. With the knowledge of tuple creation and basic functions, you can now start using tuples in your Python programs.
