What are some examples of custom serializers in programming?

Custom serializers are used to convert complex data types into a format that can be easily stored or transmitted. For example, in Python, you might create a custom serializer for a class that includes non-serializable attributes.

Can you give me a specific example in Python?

Sure! In Python, you can use the json module to create a custom serializer. For instance, if you have a class Person, you can define a method to convert it to a dictionary format that json.dumps() can handle.

How would that look in code?

Here's a simple example:

import json

class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age

    def to_dict(self):
        return {'name': self.name, 'age': self.age}

person = Person('Alice', 30)
json_data = json.dumps(person.to_dict())
print(json_data)  # Output: {"name": "Alice", "age": 30}
