[PYTHON] Handling multiple responses with codegen

I have different type of responses for different status code , consider the contents of swagger.json to be

{
	"swagger": "2.0",
	"info": {
		"title": "My Api",
		"description": "Api for Queue",
		"version": "v1"
	},
	"host": "localhost:8000",
	"schemes": ["http"],
	"basePath": "/api",
	"consumes": ["application/json"],
	"produces": ["application/json"],
	"securityDefinitions": {},
	"security": [{}],
	"paths": {
		"/v1/{name}/get_task": {
			"get": {
				"operationId": "v1_get_task_read",
				"description": "Get the first task from queue \n---",
				"parameters": [{
					"name": "priority",
					"in": "query",
					"required": false,
					"type": "string"
				}],
				"responses": {
					"200": {
						"description": "QueuedTask Object",
						"schema": {
							"$ref": "#/definitions/QueuedTask"
						}
					},
					"204": {
						"description": "null object response"
					}
				},
				"tags": ["v1"]
			},
			"parameters": [{
				"name": "name",
				"in": "path",
				"required": true,
				"type": "string"
			}]
		}
	},
	"definitions": {
		"QueuedTask": {
			"required": ["name"],
			"type": "object",
			"properties": {
				"id": {
					"title": "ID",
					"type": "integer",
					"readOnly": true
				},
				"name": {
					"title": "Name",
					"type": "string",
					"maxLength": 16
				}
			}
		}
	}
}

Swagger codegen version 2.3.1

java -jar swagger-codegen-cli-2.3.1.jar generate -l python -i swagger.json -o outs

swagger_client produced inside outs directory doesn't support None object for 204 response. It tries to deserialize the empty response into QueuedTask object and breaks.

使用提供的 swagger.json，并运行所述的 Swagger Codegen 2.3.1 Python 生成命令。检查生成的 swagger_client 对 200 和 204 响应的处理，重点关注空的 204 响应。完成的标准是，生成的客户端接受 204 响应，而不会尝试将其反序列化为 QueuedTask，同时保留 200 响应的行为。
