            title: 'Python Data Types: Lists, Tuples, Sets, Dictionaries',
            overview: `
                <p>Python provides several built-in data structures that are essential for data science work. Understanding these data types is fundamental to writing efficient Python code.</p>
                <p>Each data structure has unique characteristics that make it suitable for different use cases:</p>
                <ul>
                    <li><strong>Lists:</strong> Ordered, mutable collections that can contain duplicate elements</li>
                    <li><strong>Tuples:</strong> Ordered, immutable collections that are memory efficient</li>
                    <li><strong>Sets:</strong> Unordered collections of unique elements with fast membership testing</li>
                    <li><strong>Dictionaries:</strong> Key-value pairs for fast lookups and data mapping</li>
                </ul>
            `,
            keyConcepts: `
                <h3>Lists</h3>
                <p>Lists are the most versatile data structure in Python. They're mutable, meaning you can modify them after creation.</p>
                <ul>
                    <li>Creating lists: <code>my_list = [1, 2, 3, 'four']</code></li>
                    <li>List methods: append(), extend(), insert(), remove(), pop(), sort()</li>
                    <li>Slicing: <code>my_list[1:3]</code></li>
                    <li>List comprehensions for efficient data processing</li>
                </ul>
                
                <h3>Tuples</h3>
                <p>Tuples are immutable sequences, perfect for data that shouldn't change.</p>
                <ul>
                    <li>Creating tuples: <code>my_tuple = (1, 2, 3)</code></li>
                    <li>Unpacking: <code>x, y, z = my_tuple</code></li>
                    <li>Use cases: function return values, dictionary keys</li>
                </ul>
                
                <h3>Sets</h3>
                <p>Sets provide mathematical set operations and fast membership testing.</p>
                <ul>
                    <li>Creating sets: <code>my_set = {1, 2, 3}</code></li>
                    <li>Operations: union, intersection, difference, symmetric_difference</li>
                    <li>Removing duplicates from sequences</li>
                </ul>
                
                <h3>Dictionaries</h3>
                <p>Dictionaries are hash maps that provide O(1) average case lookup time.</p>
                <ul>
                    <li>Creating dicts: <code>my_dict = {'key': 'value'}</code></li>
                    <li>Methods: get(), keys(), values(), items(), update()</li>
                    <li>Dictionary comprehensions</li>
                </ul>
