How do I copy sets in Python across multiple processes?

In Python, when working with multiple processes, it's important to share data in a way that avoids conflicts and maintains data integrity. To copy sets across multiple processes, you can use the `multiprocessing` module, which provides a `Manager` that can help create shared objects.
multiprocessing, Python, sets, process, Manager, shared objects
from multiprocessing import Manager, Process def worker(shared_set): shared_set.add('data from process') if __name__ == '__main__': manager = Manager() shared_set = manager.set() processes = [] for _ in range(5): p = Process(target=worker, args=(shared_set,)) processes.append(p) p.start() for p in processes: p.join() print(shared_set) # Output: {'data from process'}

multiprocessing Python sets process Manager shared objects
