Topic: Python List vs Tuple — Differences and Use Cases

---

Key Differences

• Lists are mutable — you can change, add, or remove elements.

• Tuples are immutable — once created, they cannot be changed.

---

Creating Lists and Tuples

my_list = [1, 2, 3]
my_tuple = (1, 2, 3)

---

When to Use Each

• Use lists when you need a collection that can change over time.

• Use tuples when the collection should remain constant, providing safer and faster data handling.

---

Common Tuple Uses

• Returning multiple values from a function.

def get_coordinates():
    return (10, 20)

x, y = get_coordinates()

• Using as keys in dictionaries (since tuples are hashable, lists are not).

---

Converting Between Lists and Tuples

list_to_tuple = tuple(my_list)
tuple_to_list = list(my_tuple)

---

Performance Considerations

• Tuples are slightly faster than lists due to immutability.

---

Summary

• Lists: mutable, dynamic collections.

• Tuples: immutable, fixed collections.

• Choose based on whether data should change or stay constant.
