What are some advanced features of Python collections?
Python collections offer advanced features like namedtuples, defaultdicts, and Counter for efficient data handling.
Can you explain how defaultdict works?
Sure! defaultdict is a subclass of dict that provides a default value for a nonexistent key, preventing KeyErrors.
What about using namedtuples? How are they different from regular tuples?
Namedtuples allow you to access fields by name instead of index, making your code more readable and self-documenting.
Are there any performance benefits to using these advanced collections?
Yes, using specialized collections like deque or Counter can improve performance for specific tasks, like counting or fast appends.
