对 AWS cloudformation 模板的 Python 代码进行解串

如何解决对 AWS cloudformation 模板的 Python 代码进行解串

我有 python 代码的字符串化版本，我想对其进行解串，对其进行一些更改并再次对其进行字符串化。 有没有图书馆可以做同样的事情？

样本输入：

"import boto3\n\nSUCCESS_MESSAGE = \"Instance patched successfully\"\
                  \nFAILURE_MESSAGE = \"Patching failed and Instance restored to original\
                  \ state\"\n\nssm = boto3.client('ssm')\n\ndef is_compliant(ec2_id):\n\t\
                  report = {\n\t\t\"is_compliant\": None,\n\t\t\"items\": []\n\t}\n\tnoncompliance_found\
                  \ = False\n\ttoken = None\n\twhile 1:\n\t\tif token is None:\n\t\t\tlist_compliance_result\
                  \ = ssm.list_compliance_items(\n\t\t\t\tFilters=[{'Key': 'ComplianceType',\
                  \ 'Values': ['Patch']}],\n\t\t\t\tResourceIds=[ec2_id],\n\t\t\t\tResourceTypes=[\"\
                  ManagedInstance\"]\n\t\t\t)\n\n\t\telse:\n\t\t\tlist_compliance_result =\
                  \ ssm.list_compliance_items(\n\t\t\t\tFilters=[{'Key': 'ComplianceType',\n\t\t\t\tResourceTypes=[\"\
                  ManagedInstance\"],\n\t\t\t\tNextToken=token\n\t\t\t)\n\t\tcompliances =\
                  \ list_compliance_result[\"ComplianceItems\"]\n\n\t\tfor a_val in compliances:\n\
                  \t\t\tpatch_item = {\n\t\t\t\t\"PatchId\": a_val[\"Id\"],\n\t\t\t\t\"Severity\"\
                  : a_val[\"Severity\"],\n\t\t\t\t\"ComplianceType\": a_val[\"ComplianceType\"\
                  ],\n\t\t\t\t\"State\": a_val[\"Details\"][\"PatchState\"]\n\t\t\t}\n\t\t\
                  \treport[\"items\"].append(patch_item)\n\t\t\tif a_val[\"Status\"] != \"\
                  COMPLIANT\" and a_val[\"Details\"][\"PatchState\"] != \"NotApplicable\"\
                  :\n\t\t\t\tnoncompliance_found = True\n\n\t\tif \"NextToken\" in list_compliance_result:\n\
                  \t\t\ttoken = list_compliance_result[\"NextToken\"]\n\t\telse:\n\t\t\tbreak\n\
                  \n\t\tif token is None:\n\t\t\tbreak\n\n\treport[\"is_compliant\"] = noncompliance_found\
                  \ is False\n\treturn report\n\n\ndef is_success_case(ec2_id):\n\treturn\
                  \ is_compliant(ec2_id)\n\n\ndef handler(event,context):\n\tcompliance_report\
                  \ = is_success_case(event[\"InstanceId\"])\n\treturn {\n\t\t\"Result\":\
                  \ SUCCESS_MESSAGE if compliance_report[\"is_compliant\"] else FAILURE_MESSAGE,\n\
                  \t\t\"PatchingSuccess\": compliance_report[\"is_compliant\"],\n\t\t\"items\"\
                  : compliance_report[\"items\"]\n\t}\n"

输出： 格式化的python代码 类似于以下内容：

import boto3

SUCCESS_MESSAGE = "Instance patched successfully"
  
FAILURE_MESSAGE = "Patching failed and Instance restored to original state"

ssm = boto3.client('ssm')
....

反之亦然，将上述代码字符串化。

解决方法

您如何看待使用 aws cdk 并用 python 而不是 json 编写所有这些内容？
