How do I index dicts in Python across multiple processes?

In Python, when you want to access or index dictionaries across multiple processes, you can use the `multiprocessing` module along with `Manager`. This allows you to create a shared dictionary that can be accessed by multiple processes safely.

Example of Indexing Dictionaries Across Multiple Processes

import multiprocessing def update_dict(shared_dict, key, value): shared_dict[key] = value if __name__ == '__main__': manager = multiprocessing.Manager() shared_dict = manager.dict() processes = [] for i in range(5): p = multiprocessing.Process(target=update_dict, args=(shared_dict, f'key{i}', f'value{i}')) processes.append(p) p.start() for p in processes: p.join() print(dict(shared_dict)) # Convert to a regular dict for easier viewing

python multiprocessing shared dictionary index dicts cross-process data
