How do I slice sets in Python across multiple processes?

# Example Python code to slice sets across multiple processes

import multiprocessing

def worker(sliced_set):
    # Process the sliced set
    return {x * 2 for x in sliced_set}

if __name__ == "__main__":
    # Original set
    original_set = set(range(100))

    # Determine the number of processes
    num_processes = multiprocessing.cpu_count()

    # Split the set into slices
    set_slices = [set(list(original_set)[i::num_processes]) for i in range(num_processes)]

    # Create a pool of workers
    with multiprocessing.Pool(processes=num_processes) as pool:
        results = pool.map(worker, set_slices)

    # Combine results from all processes
    combined_results = set.union(*results)
    
    print(combined_results)
