How do I merge dicts in Python across multiple processes?

In Python, merging dictionaries across multiple processes can be efficiently handled using the `multiprocessing` module and either `Manager` or `Value` from `multiprocessing`. Here's how you can do it:

from multiprocessing import Process, Manager def merge_dicts(shared_dict, new_dict): for key, value in new_dict.items(): shared_dict[key] = value if __name__ == '__main__': manager = Manager() shared_dict = manager.dict() dicts_to_merge = [{'a': 1}, {'b': 2}, {'c': 3}] processes = [] for d in dicts_to_merge: p = Process(target=merge_dicts, args=(shared_dict, d)) processes.append(p) p.start() for p in processes: p.join() print(dict(shared_dict)) # Output: {'a': 1, 'b': 2, 'c': 3}
