How do I compare dicts in Python across multiple processes?

In Python, comparing dictionaries across multiple processes requires careful attention to how data is shared between processes. One common approach is using the `multiprocessing` module along with the `Manager` class, which allows for shared objects. Here’s an example of how to compare dictionaries across multiple processes.

import multiprocessing def compare_dicts(dict1, dict2, return_dict): return_dict['result'] = dict1 == dict2 if __name__ == '__main__': manager = multiprocessing.Manager() return_dict = manager.dict() dict_a = {'key1': 'value1', 'key2': 'value2'} dict_b = {'key1': 'value1', 'key2': 'value2'} process = multiprocessing.Process(target=compare_dicts, args=(dict_a, dict_b, return_dict)) process.start() process.join() print("Dictionaries are equal:", return_dict['result'])
