Tuple in Python [ English ]

Languages

• English

1. Introduction

A tuple in Python is a collection of items stored in a single variable, similar to a list. However, the key difference is:

Tuples are immutable (cannot be changed after creation)

2. Characteristics of Tuple

• Ordered (elements have fixed positions)
• Immutable (cannot modify elements)
• Allows duplicate values
• Can store different data types

3. Creating a Tuple

Syntax

tuple_name = (elements)

Example

numbers = (1, 2, 3)names = ("Amit", "Rahul", "Priya")mixed = (10, "Python", 3.5)

Single Element Tuple

t = (5,)

👉 Comma is required, otherwise it is not considered a tuple.

4. Accessing Elements

Indexing

numbers = (10, 20, 30) print(numbers[0])print(numbers[1])

Output

1020

Negative Indexing

print(numbers[-1])

Output

30

5. Slicing a Tuple

numbers = (1, 2, 3, 4, 5) print(numbers[1:4])

Output

(2, 3, 4)

6. Immutability of Tuple

numbers = (1, 2, 3) numbers[1] = 10 # Error

Explanation

• Tuples cannot be modified after creation.

7. Tuple Operations

Concatenation

a = (1, 2)b = (3, 4) print(a + b)

Repetition

print((1, 2) * 2)

Membership

print(2 in (1, 2, 3))

8. Looping Through a Tuple

numbers = (1, 2, 3) for n in numbers: print(n)

9. Tuple Packing and Unpacking

Packing

t = 1, 2, 3

Unpacking

a, b, c = (1, 2, 3) print(a, b, c)

10. Nested Tuple

t = ((1, 2), (3, 4)) print(t[0][1])

Output

2

11. Built-in Functions for Tuple

12. Difference Between List and Tuple

13. Advantages of Tuple

• Faster than lists
• Protects data (immutable)
• Can be used as dictionary keys
• Uses less memory

14. Summary

• A tuple is an ordered and immutable collection

• Created using parentheses ( )

• Supports:

  • indexing
  • slicing
  • iteration

• Cannot be modified after creation

• Useful for fixed and secure data
