How do I deduplicate lists in Python with type hints?

In Python, you can deduplicate lists using several methods, including converting the list to a set, using dictionary keys, or employing list comprehensions. Below is an example with type hints demonstrating how to remove duplicates from a list while preserving the order.

from typing import List def deduplicate_list(input_list: List[int]) -> List[int]: seen = set() deduplicated = [] for item in input_list: if item not in seen: seen.add(item) deduplicated.append(item) return deduplicated # Example usage: input_list = [1, 2, 2, 3, 4, 4, 5] output_list = deduplicate_list(input_list) print(output_list) # Output: [1, 2, 3, 4, 5]
