How do I deduplicate tuples in Python with type hints?

In Python, you can deduplicate tuples by converting them into a set and then back to a tuple. This method eliminates duplicate entries while maintaining the type hints for better code clarity. Below is an example of how to achieve this:

from typing import List, Tuple def deduplicate_tuples(tuples: List[Tuple[int, str]]) -> List[Tuple[int, str]]: """Remove duplicate tuples from a list of tuples.""" # Convert the list of tuples into a set to remove duplicates unique_tuples = set(tuples) # Convert it back to a list and return return list(unique_tuples) # Example usage example_tuples = [(1, 'apple'), (2, 'banana'), (1, 'apple'), (3, 'cherry')] deduplicated = deduplicate_tuples(example_tuples) print(deduplicated)
