How Can I Handle 'datetime.datetime not JSON serializable' Errors in Python?

JSON Serialization of Datetime Objects

Encountering the "datetime.datetime not JSON serializable" error while attempting to jsonify dictionaries containing datetime objects highlights the need to address the JSON serialization limitations of Python's datetime type. To address this problem effectively, the following solution is proposed:

A customizable JSON serialization approach allows for the conversion of non-serializable objects, such as datetime, into JSON-compatible formats. By utilizing the default parameter in json.dumps(), you can define a function that handles the conversion of datetime objects.

For instance, a simple default function that converts datetime objects to strings can be implemented as follows:

def convert_datetime(o):
    if isinstance(o, datetime):
        return str(o)
    return o

By passing this function as the default argument to json.dumps(), you can ensure that datetime objects are converted to strings and serialized successfully:

json.dumps(sample, indent=4, sort_keys=True, default=convert_datetime)

This approach provides a flexible and customizable solution for serializing complex data structures, including those containing datetime objects, into JSON format.
