How can I serialize Python namedtuples?

How can I serialize Python namedtuples?

You can serialize Python namedtuples using the pickle module or by converting them to dictionaries.

Can you show me an example using pickle?

Sure! Here's a simple example:

import pickle
from collections import namedtuple

Person = namedtuple('Person', ['name', 'age'])

# Create a namedtuple instance
person = Person(name='Alice', age=30)

# Serialize the namedtuple
with open('person.pkl', 'wb') as f:
    pickle.dump(person, f)

# Deserialize the namedtuple
with open('person.pkl', 'rb') as f:
    loaded_person = pickle.load(f)

print(loaded_person)

What if I want to serialize it to JSON instead?

You can convert the namedtuple to a dictionary and then use the json module. Here's how:

import json
from collections import namedtuple

Person = namedtuple('Person', ['name', 'age'])

# Create a namedtuple instance
person = Person(name='Alice', age=30)

# Convert to dictionary and serialize to JSON
person_json = json.dumps(person._asdict())
print(person_json)
