How do I serialize dicts in Python in a memory-efficient way?

In Python, you can serialize dictionaries in a memory-efficient way using the `json` or `pickle` modules, depending on your requirements. The `json` module is suitable for lightweight serialization, whereas `pickle` is more versatile but can use more memory. Here’s an example of how to use both methods:

import json import pickle # Example dictionary data = {'name': 'Alice', 'age': 30, 'city': 'New York'} # Serialize using json json_serialized = json.dumps(data) # Serialize using pickle pickle_serialized = pickle.dumps(data) # Optionally, write to a file for persistence with open('data.json', 'w') as json_file: json_file.write(json_serialized) with open('data.pkl', 'wb') as pickle_file: pickle_file.write(pickle_serialized)
