In Python, when working with dictionaries, you may encounter situations where you need to remove duplicate dictionaries from a collection, especially in an asynchronous application. Below is an example of how to achieve this using Python's built-in functionalities, along with asynchronous programming principles.
import asyncio
async def deduplicate_dicts(dict_list):
seen = set()
unique_dicts = []
for d in dict_list:
# Create a hashable representation of the dictionary
dict_tuple = tuple(sorted(d.items()))
if dict_tuple not in seen:
seen.add(dict_tuple)
unique_dicts.append(d)
return unique_dicts
async def main():
dicts = [
{'id': 1, 'name': 'Alice'},
{'id': 2, 'name': 'Bob'},
{'id': 1, 'name': 'Alice'}, # Duplicate
]
deduped = await deduplicate_dicts(dicts)
print(deduped)
asyncio.run(main())
