Select the true statements about the json.-dumps () function. (Select two answers.)

The json.dumps() function is used for serialization, which is the process of converting a Python object into a JSON formatted string. The function's name itself, "dump string," indicates its purpose. It takes a Python data structure (like a dictionary or list) as its primary argument and returns a str object representing that data in JSON format. This process is essential for storing data or transmitting it over a network in a standardized, language-independent format.

B. It returns a Python entity.

This describes the deserialization function json.loads(), which parses a JSON string and converts it back into a Python object.

C. It takes a JSON string as its argument.

This is also a description of json.loads(), which requires a JSON-formatted string as input for deserialization.

1. Official Python Documentation: The documentation for the json module explicitly states, "Serialize obj to a JSON formatted str using this conversion table." This confirms that the function takes a Python object (obj) as an argument (D) and returns a JSON formatted string (A).

2. University Courseware (MIT OpenCourseWare): In the lecture notes for "Introduction to Computer Science and Programming in Python," the process of using the json library is detailed. The examples show json.dumps() being called with a Python dictionary as an argument to produce a string, reinforcing that it takes Python data and returns a string.

3. University Courseware (University of Michigan): The "Python for Everybody" course materials, widely adopted by universities, explain that json.dumps() is used to "take a Python data structure and put it into a string." This directly supports both correct answers.
