Lists & Tuples

Lists

List ek ordered collection hai jisme multiple values store kar sakte hain. Lists ko [] (square brackets) se banaya jata hai.

# Example of a list
fruits = ["apple", "banana", "mango"]
print(fruits)

Output:

['apple', 'banana', 'mango']

List ke elements access karna

print(fruits[0])   # apple
print(fruits[1])   # banana

List ke elements update karna

fruits[1] = "orange"
print(fruits)

Output:

['apple', 'orange', 'mango']

List me element add karna

fruits.append("grapes")
print(fruits)

Output:

['apple', 'orange', 'mango', 'grapes']

Tuples

Tuple bhi list jaisa hota hai, lekin immutable (change nahi kar sakte). Tuple ko () (round brackets) se banaya jata hai.

# Example of a tuple
coordinates = (10, 20, 30)
print(coordinates)

Output:

(10, 20, 30)

Tuple access karna

print(coordinates[0])   # 10

Tuple change karne ki koshish

coordinates[0] = 50   # Error aayega

Output:

TypeError: 'tuple' object does not support item assignment

Lists vs Tuples

• List → mutable (badal sakte hain)
• Tuple → immutable (fix ho jata hai)
• List use hota hai jab data change hoga
• Tuple use hota hai jab data fix hai (jaise coordinates, constants)
