使用python 3从嵌套JSON中提取数据

正在寻找从嵌套json中提取数据的方法。 数据以xml形式从windows调度器中提取，并转换为json。 它代表操作系统计划的任务，大约有100个任务，我的目标是将信息从json提取到外部数据库。 这就是我的json文件的样子：

下面的代码只适用于一个任务，但我需要从每个任务中获取数据，我想我需要找到一种方法，将任务数插入到index的值中，并逐个循环，但我尝试的方法都不起作用

import json
index=1

with open('name.json', 'r') as f:
    array = json.load(f)

ts=(array['Tasks'])
print('Author is',ts['Task'][index]['RegistrationInfo']['Author'])
print('Description is' ,ts['Task'][index]['RegistrationInfo']['Description'])
print('URI is',ts['Task'][index]['RegistrationInfo']['URI'])
print('user ID is', ts['Task'][index]['Principals']['Principal']['UserId'])
print('Logon Type  is', ts['Task'][index]['Principals']['Principal']['LogonType'])
print(' ID is', ts['Task'][index]['Principals']['Principal']['_id'])
print(' DisallowStartIfOnBatteries is ', ts['Task'][index]['Settings']['DisallowStartIfOnBatteries'])
print(' StopIfGoingOnBatteries is ', ts['Task'][index]['Settings']['StopIfGoingOnBatteries'])
print(' MultipleInstancesPolicy is ', ts['Task'][index]['Settings']['MultipleInstancesPolicy'])
print(' StartWhenAvailable is ', ts['Task'][index]['Settings']['StartWhenAvailable'])
print(' RunOnlyIfNetworkAvailable is ', ts['Task'][index]['Settings']['RunOnlyIfNetworkAvailable'])

你以前用过循环吗？常规循环？当然。那就迭代任务？这是我有问题的部分。当尝试迭代时，它不起作用。甚至无法计算文件中的任务数。我很乐意提供帮助，但我仍然不确定您需要打印什么。代码中显示的那些任务具有各种属性。您如何知道要从每个任务中提取哪些描述和属性？以前是否使用过循环？常规循环？当然。那就迭代任务？这是我有问题的部分。当尝试迭代时，它不起作用。甚至无法计算文件中的任务数。我很乐意提供帮助，但我仍然不确定您需要打印什么。代码中显示的那些任务具有各种属性。您如何知道要从每个任务中提取哪些描述和属性？
