How to make a Python class JSON serializable

You have a simple class as follows

class MyClass:
    def __init__(self):
        self.name = 'Python'
        self.value = 'Easy'

You want to serialize the class attributes to JSON as follows

{
    "name": "Python",
    "value": "Easy"
}

You can add a to_json() method to convert the attributes to  class. Here is the code

import json
class MyClass:
    def __init__(self):
        self.name = 'Python'
        self.value = 'Easy'

    def to_json(self):
        return json.dumps(self, default=lambda o: o.__dict__,
                          sort_keys=True, indent=4)

instance = MyClass()
print(instance.to_json())

{
    "name": "Python",
    "value": "Easy"
}
