Lists, tuples, dictionaries, sets, and complex data handling
Learn everything about Python lists — how to create, access, modify, sort, and loop through them with practical examples and exercises.
Master Python comprehensions — list, dict, set, and generator expressions. Transform loops into elegant one-liners with filtering, mapping, and conditional logic.
Master Python tuples — immutable sequences for fixed data. Learn tuple creation, packing, unpacking, indexing, when to use tuples vs lists, and real-world patterns.
Master Python dictionaries — create, access, modify, and loop through key-value pairs. Learn dict methods, nested dicts, and real-world patterns with interactive examples.
Master Python sets — unique, unordered collections. Learn set creation, operations (union, intersection, difference), methods, and real-world deduplication patterns.
Master Python slicing with start:stop:step notation. Learn to extract portions of strings, lists, and tuples, reverse sequences, and use negative indices.
Master Python unpacking — assign multiple values at once, swap variables, use starred expressions (*), and destructure nested data structures.
Master Python sorting with sort(), sorted(), reverse parameter, key functions, and lambda-based custom sorting. Learn to sort any data the way you need.
Learn to work with nested Python data: lists of dicts, dicts of lists, JSON-like structures. Master accessing, modifying, and iterating through complex data.
