What json dumps do?

The json.dumps() function in Python converts Python objects into JSON-formatted strings, similar to JSON.stringify() in JavaScript. This function is essential for serializing Python dictionaries, lists, and other data types into JSON for API responses, file storage, or data transmission. The function accepts parameters like indent for pretty-printing, sort_keys for ordered output, and ensure_ascii for handling Unicode characters. For example, json.dumps({"name": "John"}) returns '{"name": "John"}'. Python objects like datetime require custom serializers since they are not natively JSON-serializable. The counterpart function json.loads() deserializes JSON strings back to Python objects. Together, these functions enable seamless JSON data exchange in Python applications, web services, and data processing pipelines, making Python ideal for working with JSON APIs.
