60. Persistence with JSON

Tasks should persist between runs. Use the json module for storage.

Saving Tasks​

import json

def save_tasks(filename="tasks.json"):
    with open(filename, "w") as f:
        json.dump(tasks, f)

Loading Tasks​

def load_tasks(filename="tasks.json"):
    global tasks
    try:
        with open(filename) as f:
            tasks = json.load(f)
    except FileNotFoundError:
        tasks = []

Wrap-Up​

JSON storage makes the Task Manager persistent and portable.
