如何將 JSON 文件中的特定項目打印到 python 中

Question

我想將 JSON 列表中的用戶打印到我選擇的 Python 中，但是我只能打印所有用戶。 如何打印特定用戶？ 目前我有這個以丑陋的格式打印所有用戶

import json

with open('Admin_sample.json') as f:
    admin_json = json.load(f)

print(admin_json['staff'])

JSON 文件如下所示

{
"staff": [
    {
        "id": "DA7153",
        "name": [
            "Fran\u00c3\u00a7ois",
            "Ullman"
        ],
        "department": {
            "name": "Admin"
        },
        "server_admin": "true"
    },
    {
        "id": "DA7356",
        "name": [
            "Bob",
            "Johnson"
        ],
        "department": {
            "name": "Admin"
        },
        "server_admin": "false"
    },
],
"assets": [
    {
        "asset_name": "ENGAGED SLOTH",
        "asset_type": "File",
        "owner": "DA8333",
        "details": {
            "security": {
                "cia": [
                    "HIGH",
                    "INTERMEDIATE",
                    "LOW"
                ],
                "data_categories": {
                    "Personal": "true",
                    "Personal Sensitive": "true",
                    "Customer Sensitive": "true"
                }
            },
            "retention": 2
        },
        "file_type": "Document",
        "server": {
            "server_name": "ISOLATED UGUISU",
            "ip": [
                10,
                234,
                148,
                52
            ]
        }
    },
    {
        "asset_name": "ISOLATED VIPER",
        "asset_type": "File",
        "owner": "DA8262",
        "details": {
            "security": {
                "cia": [
                    "LOW",
                    "HIGH",
                    "LOW"
                ],
                "data_categories": {
                    "Personal": "false",
                    "Personal Sensitive": "false",
                    "Customer Sensitive": "true"
                }
            },
            "retention": 2
        },
    },
]

我就是搞不定。 任何幫助，將不勝感激。

謝謝。

Answer 1

您需要索引到staff列表中，例如：

print(admin_json['staff'][0])

我建議閱讀一些Python 詞典。 字典值可以設置為任何對象：在這種情況下， staff鍵的值設置為字典列表。 這是一個示例，它將遍歷所有員工並打印他們的姓名：

staff_list = admin_json['staff']
for person in staff_list:
    name_parts = person['name']
    full_name = ' '.join(name_parts)  # combine name parts into a string
    print(full_name)

Answer 2

嘗試這樣的事情：

import json

def findStaffWithId(allStaff, id):
    for staff in allStaff:
        if staff["id"] == id:
            return staff
    return {}  # no staff found

with open('Admin_sample.json') as f:
    admin_json = json.load(f)

print(findStaffWithId(admin_json['staff'], "DA7356"))

Answer 3

您可以列出所有用戶名

users = [user["name"] for user in admin_json['staff']]

Answer 4

此 JSON 文件中有兩個列表。 當您嘗試解析它時，您將獲得一個列表。 例如獲取第一個員工 ID：

print(admin_json['staff'][0]['id'])

這將打印：

DA7153

當您使用“json.loads”時，這只會將 JSON 文件轉換為 Python 字典。 更多信息： https : //docs.python.org/3/tutorial/datastructures.html#dictionaries
