For coding interviews in Python, focus on these essential data structures:
- Lists: Used for dynamic arrays that support fast access, insertion, and deletion.
- Dictionaries: Implement hash tables for efficient key-value storage and lookups.
- Sets: Store unique elements and provide fast membership checks.
- Tuples: Immutable sequences used for fixed-size collections.
- Queues and stacks: Use collections.deque for double-ended queues, which can also efficiently implement stacks and queues.
- Heaps: Use heapq for priority queues.
- Linked lists, trees, and graphs: Implement manually using classes to handle more complex problems.
Mastering these structures and their operations will prepare you well for Python coding interviews.
