Python基础(YAML与JSON转换)

使用模块：json，yaml(PyYaml)

    app: nginx

        volumeMounts:

          subPath: nginx
      volumes:
      - name: storage
        persistentVolumeClaim:
          claimName: nginx

                        "ports": [
                            {
                                "containerPort": 80
                            }
                        ],
                        "volumeMounts": [
                            {
                                "mountPath": "/usr/share/nginx/html",
                                "subPath": "nginx",
                                "name": "storage"
                            }
                        ]
                    }
                ],
                "volumes": [
                    {
                        "name": "storage",
                        "persistentVolumeClaim": {
                            "claimName": "nginx"
                        }
                    }
                ]
            }
        }
    }
}

YAML转JSON

思路：

1. 使用yaml模块中的load函数将yaml转换为dict格式
2. 使用json模块中的dumps函数将dict转换为json格式

eg：

import json,yaml
test_file = open(test_yaml_file,"r")
#先将yaml转换为dict格式
generate_dict = yaml.load(test_file,Loader=yaml.FullLoader)
generate_json = json.dumps(generate_dict,sort_keys=False,indent=4,separators=(',',': '))
print(generate_json)

JSON转YAML

思路：

1. 使用json模块中的loads模块将json转换为dict
2. 使用yaml模块中的dump函数将dict转换为yaml格式

import yaml,json
test_file = open(test_json_file,"r")
test_json = json.loads(test_file)
test_dict = test_json
test_yaml = yaml.dump(test_dict)
#或者直接转换为文件
new_yaml_file = open("new_file","w")
yaml.safe_dump(test_dict,stream=new_yaml_file,default_flow_style=False)
