Python 变量似乎是 json，但始终带有引号

Question

我是 Python 新手；在这里使用 Jupyter nb。

将变量设置为az cli 命令的结果时，我得到一个json 数组，但其中包含单引号。

当我单独运行命令而不将其设置为变量时，响应是干净的 json。

如何将变量结果作为干净的 json？

示例 1：（已通过使用 .join 修复，如 cmets 中所述）

new_mi = !az identity create --name $mi_name --resource-group $rg_name --location $rc_location
new_mi
['{',
 '  "clientId": "redacto",',
 '  "clientSecretUrl": "https://control-westus2.identity.azure.net/subscriptions/redacto/resourcegroups/rg_azureFunction/providers/Microsoft.ManagedIdentity/userAssignedIdentities/mi_azureFunction/credentials?tid=redacto&oid=redacto&aid=redacto",',
 '  "id": "/subscriptions/redacto/resourcegroups/rg_azureFunction/providers/Microsoft.ManagedIdentity/userAssignedIdentities/mi_azureFunction",',
 '  "location": "westus2",',
 '  "name": "mi_azureFunction",',
 '  "principalId": "redacto",',
 '  "resourceGroup": "rg_azureFunction",',
 '  "tags": {',
 '    "lang": "python",',
 '    "owner": "redacto",',
 '    "project": "test"',
 '  },',
 '  "tenantId": "redacto",',
 '  "type": "Microsoft.ManagedIdentity/userAssignedIdentities"',
 '}']

示例2：不同的az cli 命令，但.join 在这里不起作用

• 我不认为响应，即使.join 是有效的 json，因为开头的消息。
• 如何跳过此步骤并直接转到 .join 的 json 对象？

sa_new = !az storage account create --name $sa_name --resource-group $rg_name --access-tier Cool --default-action Deny --kind StorageV2 --sku Standard_LRS --subscription $sub_id --tags $sa_tags

sa_new

sa_new = json.loads("\n".join(sa_new))

JSONDecodeError: Expecting value: line 1 column 1 (char 0)

Example3：此命令有同样的问题，顶部的“WARNING”消息使响应无效 JSON

az_new = !az functionapp create --consumption-plan-location westus --name $af_name --os-type Linux --resource-group $rg_name --runtime python --storage-account $sa_name --disable-app-insights true

az_new

 '  "clientAffinityEnabled": false,',...

Answer 1

当您在 Jupyter 中使用 ! 运行命令时，它会将输出作为行列表返回。更方便的方法可能是使用os.popen 或subprocess.run 或类似命令，然后解析json。

import os
import json

json.loads(os.popen("az identity create --name $mi_name --resource-group $rg_name --location $rc_location
new_mi").read())
