🔍 Quick Lesson: What Are Data Structures?
Data structures are ways to store and organize data so it can be used efficiently. Python provides several built-in structures, but the most common are:
- Lists: Ordered, changeable collections of items. Great for sequences of values.
- Dictionaries: Unordered collections of key-value pairs. Ideal for mapping data.
Understanding data structures is essential to writing clean, effective Python code. They allow you to group data, search and manipulate it, and manage complexity.

List example:
fruits = ["apple", "banana", "cherry"]
print(fruits[1]) # Output: banana
Dictionary example:
person = {"name": "Alice", "age": 25}
print(person["name"]) # Output: Alice
