How do I deduplicate dicts in Python for production systems?

Deduplicating dictionaries in Python can be crucial for production systems to ensure data integrity and optimize performance. Here is a method to achieve this using a combination of a set and list comprehension.


# Example of deduplicating a list of dictionaries
data = [
    {'id': 1, 'name': 'Alice'},
    {'id': 2, 'name': 'Bob'},
    {'id': 1, 'name': 'Alice'},  # Duplicate
    {'id': 3, 'name': 'Charlie'}
]

# Deduplicating the list of dictionaries
unique_data = [dict(t) for t in {tuple(d.items()) for d in data}]

print(unique_data)  # Output: [{'id': 1, 'name': 'Alice'}, {'id': 2, 'name': 'Bob'}, {'id': 3, 'name': 'Charlie'}]
