从json文件创建Python活动资源对象

import json

# 读取JSON文件
with open('data.json') as file:
    data = json.load(file)

class Activity:
    def __init__(self, id, name, duration):
        self.id = id
        self.name = name
        self.duration = duration

# 创建活动资源对象列表
activities = []
for item in data['activities']:
    activity = Activity(item['id'], item['name'], item['duration'])
    activities.append(activity)

# 打印活动资源对象的属性
for activity in activities:
    print(f"ID: {activity.id}, Name: {activity.name}, Duration: {activity.duration}")

# 修改活动资源对象的属性
activities[0].name = "Updated Name"

# 计算总时长
total_duration = sum(activity.duration for activity in activities)
print(f"Total Duration: {total_duration}")
