数据需要以这种格式存储

data = {'admin': [{'title': 'Register Users with taskManager.py', 'description': 'Use taskManager.py to add the usernames and passwords for all team members that will be using this program.', 'due date': '10 Oct 2019', 'date assigned': '20 Oct 2019', 'status': 'No'}, {'title': 'Assign initial tasks', 'description': 'Use taskManager.py to assign each team member with appropriate tasks', 'due date': '10 Oct 2019', 'date assigned': '25 Oct 2019', 'status': 'No'}], 'new user': [{'title': 'Take out trash', 'description': 'Take the trash can down the street', 'due date': '10 oct 2022', 'date assigned': '20 Oct 2022', 'status': 'No'}]}

我需要像这样显示这些数据：

user: admin

title: Register Users with taskManager.py
description: Use taskManager.py to add the usernames and passwords for all team members that will be using this program
date assigned: 10 Oct 2019
due date: 20 Oct 2022
status: No


title: Assign initial tasks
description: Use taskManager.py to assign each team member with appropriate tasks
date assigned: 10 Oct 2019
due date: 25 Oct 2019
status: No

user: new user

title: Take out trash
description: Take the trash can down the street
date assigned: 10 Oct 2022
due date: 20 Oct 202
status: No

我该怎么做呢？

你试过什么了？发布脚本以显示您需要帮助的地方。您可以使用 for 循环迭代项目（键/值对），然后迭代列表的值。

标签： python list dictionary

【解决方案1】：

尝试这个：

dict = #your dict here
for user in dict.values():
  print(f"user: {user}")
  for k, v in dict[user]: # selects sub dicts
    print (f"{k}: {v})

【解决方案2】：

你基本上有一个密集嵌套的结构，所以如果这是你数据的最终结构，那么最简单的方法是使用dict.items() 以硬编码的方式解开它，如下所示：

data = {'admin': [{'title': 'Register Users with taskManager.py', 'description': 'Use taskManager.py to add the usernames and passwords for all team members that will be using this program.', 'due date': '10 Oct 2019', 'date assigned': '20 Oct 2019', 'status': 'No'}, {'title': 'Assign initial tasks', 'description': 'Use taskManager.py to assign each team member with appropriate tasks', 'due date': '10 Oct 2019', 'date assigned': '25 Oct 2019', 'status': 'No'}], 'new user': [{'title': 'Take out trash', 'description': 'Take the trash can down the street', 'due date': '10 oct 2022', 'date assigned': '20 Oct 2022', 'status': 'No'}]}


for user, tasks in data.items():
    print("user:", user)
    for task in tasks:
        print()
        for field, value in task.items():
            print(f"{field}: {value}")
        print()

这会产生所需的输出：

user: admin

title: Register Users with taskManager.py
description: Use taskManager.py to add the usernames and passwords for all team members that will be using this program.
due date: 10 Oct 2019
date assigned: 20 Oct 2019
status: No


title: Assign initial tasks
description: Use taskManager.py to assign each team member with appropriate tasks
due date: 10 Oct 2019
date assigned: 25 Oct 2019
status: No

user: new user

title: Take out trash
description: Take the trash can down the street
due date: 10 oct 2022
date assigned: 20 Oct 2022
status: No

【解决方案3】：

循环按键以打印数据。之后您可能想要添加额外的格式以提高可读性。

for i in data.keys():
    print(f"user: {i}")
    for j in data[i]:
        for k in j.keys():
            print(f"{k}: {j[k]}")
