Python's Day 9 tutorial covers three core data structures: tuples (immutable ordered collections), sets (unique unordered items), and dictionaries (key-value pairs), each with syntax, methods, and use cases. Choosing the right structure directly impacts code correctness and performance — tuples for fixed data integrity, sets for O(1) membership testing and deduplication, dictionaries for structured record access patterns common in APIs and databases.
