Question
Python's built-in dict (dictionary) data structure is typically implemented using a hash table. What is the average-case time complexity for get, set, and del operations in a Python dictionary?
Solution
Python's dict is implemented as a hash table. On average, operations like get, set (insertion/update), and del (deletion) have a constant time complexity, O(1), assuming a good hash function and effective collision resolution.
