How do I deduplicate dicts in Python with standard library only?

In Python, you can deduplicate dictionaries using standard library functionality. One common approach is to convert the list of dictionaries into a list of tuples (using the `items()` method) and then use the built-in `set()` function to remove duplicates. Here’s how you can do it.

# Example of deduplicating a list of dictionaries dicts = [ {'id': 1, 'name': 'Alice'}, {'id': 2, 'name': 'Bob'}, {'id': 1, 'name': 'Alice'}, # Duplicate ] # Deduplication using a set deduped = {tuple(d.items()): d for d in dicts}.values() print(list(deduped)) # Output: [{'id': 1, 'name': 'Alice'}, {'id': 2, 'name': 'Bob'}]
