Python Tuples

Tuples are an immutable and ordered collection of elements in Python. Unlike lists, tuples cannot be changed after creation.

Creating a Tuple

# Creating a tuple
numbers = (1, 2, 3, 4, 5)

# Tuple with mixed data types
mixed_tuple = (1, "Hello", 3.14, True)

print(numbers)
print(mixed_tuple)
        

Accessing Tuple Elements

fruits = ("Apple", "Banana", "Cherry")

print(fruits[0])  # First element
print(fruits[-1])  # Last element
        

Tuple Immutability

fruits = ("Apple", "Banana", "Cherry")
fruits[1] = "Mango"  # This will raise an error since tuples are immutable
        

Tuple Unpacking

coordinates = (10, 20, 30)
x, y, z = coordinates
print(x, y, z)
        

Looping Through a Tuple

fruits = ("Apple", "Banana", "Cherry")
for fruit in fruits:
    print(fruit)
        

Checking If an Item Exists

fruits = ("Apple", "Banana", "Cherry")
if "Apple" in fruits:
    print("Yes, Apple is in the tuple")
        

Tuple Concatenation

tuple1 = (1, 2, 3)
tuple2 = (4, 5, 6)
result = tuple1 + tuple2
print(result)  # Output: (1, 2, 3, 4, 5, 6)
        

Finding Length of a Tuple

numbers = (10, 20, 30, 40)
print(len(numbers))  # Output: 4
        

Tuple Methods

numbers = (1, 2, 2, 3, 4, 2)
print(numbers.count(2))  # Counts occurrences of 2
print(numbers.index(3))   # Finds index of value 3
        

Conclusion

Tuples are a useful data structure in Python when you need an ordered and unchangeable sequence of elements.
