How to Solve the 'datetime.datetime is not JSON serializable' Error in Python?

Overcoming "datetime.datetime not JSON serializable" Error

When serializing a Python dictionary containing a datetime object, such as in the example provided, an error may occur: TypeError: datetime.datetime is not JSON serializable.

Solution:

One approach to resolve this issue is to specify a custom default function while serializing the dictionary into JSON. This function will handle the conversion of non-serializable objects, such as datetime objects, into a JSON-compatible format.

import json

sample = {}
sample['title'] = "String"
sample['somedate'] = datetime.datetime(2012, 8, 8, 21, 46, 24, 862000)

def datetime_handler(x):
    if isinstance(x, datetime.datetime):
        return x.isoformat()
    raise TypeError("Unknown type")

json_string = json.dumps(sample, default=datetime_handler)

In this solution, the datetime_handler function is defined to convert datetime objects into a string representation using the isoformat() method. This string representation can then be handled appropriately during deserialization.

By providing a custom default function like this, you can successfully convert your dictionary containing datetime objects into a JSON-serializable format.
