What is tuple in python

A tuple in Python is an ordered collection of elements, similar to a list. Tuple is built-in data types in Python used to store collections of data. The difference between the two is that we cannot change the elements of a tuple once it is assigned whereas we can change the elements of a list. 

A tuple is created by placing all the items (elements) inside parentheses (), separated by commas.

Syntax:

my_tuple = (1, 2, 3)

Or even without parentheses (though parentheses are recommended):

my_tuple = 1, 2, 3

Tuple Operations

• Indexing

t = ('a', 'b', 'c')
print(t[0])  

Output: # 'a'

• Slicing

t = ('a', 'b', 'c')
print(t[1:]) 

Output:  # ('b', 'c')

• Iteration

t = ('a', 'b', 'c')
for item in t:
    print(item)

Q: According to user choice enter some elements in tuple.

mytupule=()
ch=int(input("enter elements"));
for i in range(ch):
    a=int(input("enter a number"));
    mytupule=mytupule+(a,);
print(mytupule);

Tuple Methods

Tuples have only 2 built-in methods:

my_tuple = (1, 2, 3, 2)
my_tuple.count(2)     # 2
my_tuple.index(3)     # 2

Example:

# Creating Tuples

empty_tuple = ()

single_item = (42,)

multi_items = (1, 2, 3, 4)

print("Empty Tuple:", empty_tuple)

print("Single-item Tuple:", single_item)

print("Multi-item Tuple:", multi_items)

# Indexing and Slicing

print("First Element:", multi_items[0])

print("Slice [1:3]:", multi_items[1:3])

# Tuple with different data types

mixed_tuple = ("Python", 3.10, True)

print("Mixed Tuple:", mixed_tuple)

# Tuple Packing and Unpacking

person = ("Alice", 28, "Developer")

name, age, profession = person

print(f"Name: {name}, Age: {age}, Profession: {profession}")

# Extended Unpacking

a, *b = (10, 20, 30, 40)

print("a:", a)      # 10

print("b:", b)      # [20, 30, 40]

# Iterating over a tuple

print("Iterating over a tuple:")

for item in multi_items:

    print(item)

# Membership test

print("Is 3 in multi_items?", 3 in multi_items)

# Length of tuple

print("Length of multi_items:", len(multi_items))

# Concatenation and Repetition

t1 = (1, 2)

t2 = (3, 4)

print("Concatenated Tuple:", t1 + t2)

print("Repeated Tuple:", t1 * 2)

# Tuple Methods

numbers = (1, 2, 3, 2, 4, 2)

print("Count of 2:", numbers.count(2))

print("Index of 3:", numbers.index(3))

# Nested Tuples

nested = (1, (2, 3), [4, 5])

print("Nested Tuple:", nested)

# Modifying mutable element inside tuple

nested[2].append(6)

print("Modified Nested Tuple:", nested)
