如何在python3中将字典列表保存到.mat文件？

Question

我有一个字典清单。这是列表的一个元素： mylist [1]给出以下判词。

   "ServerlessRestApi": {
        "Type": "AWS::ApiGateway::RestApi",
        "Properties": {
            "Description":"This is a placeholder for the description of this web api",
            "ApiKeySourceType":"HEADER",
            "Body": {
                "info": {
                    "version": "1.0",
                    "title": {
                        "Ref": "AWS::StackName"
                    }
                },
                "paths": {
                    "/list/tables": {
                        "get": {
                            "x-amazon-apigateway-integration": {
                                "httpMethod": "POST",
                                "type": "aws_proxy",

                                }
                            },
                            "security": [
                                {
                                   "api_key": []
                                }
                             ],
                            "responses": {}
                        }
                    },
                    "/list/columns/{tableid}": {
                        "get": {
                            "x-amazon-apigateway-integration": {
                                "httpMethod": "POST",
                                "type": "aws_proxy",
                                "uri": {
                                    "Fn::Sub": "arn:aws:apigateway:${AWS::Region}:lambda:path/2015-03-31/functions/${GetColumnList.Arn}/invocations"
                                }
                            },
                            "responses": {}
                        }
                    },
                    "datagw/general/table/get/{tableid}": {
                        "get": {

                                "uri": {

                                }
                            },
                            "responses": {}
                        }
                    },
                    "/": {
                        "get": {
                            "x-amazon-apigateway-integration": {
                                "httpMethod": "POST",
                                "type": "aws_proxy",
                                "uri": {
                                    "Fn::Sub": "arn:aws:apigateway:${AWS::Region}:lambda:path/2015-03-31/functions/${Get.Arn}/invocations"
                                }
                            },
                            "responses": {}
                        }
                    },
                    "/tables/{tableid}/{columnid}": {
                        "get": {
                            "x-amazon-apigateway-integration": {
                                "httpMethod": "POST",
                                "type": "aws_proxy",
                                "uri": {
                                    "Fn::Sub": "arn:aws:apigateway:${AWS::Region}:lambda:path/2015-03-31/functions/${GetTableBasic.Arn}/invocations"
                                }
                            },
                            "responses": {}
                        }
                    },
                    "securityDefinitions": {
                        "type": "api_key",
                        "name": "x-api-key",
                        "in": "header"
                      }
                },
                "swagger": "2.0"
            }
        }
    },

我在以下非常简化的for循环中创建每个字典：

{'bitrate': None,
 'channels': None,
 'duration': 107.927,
 'filename': 'CANCION DE POKEMON GO  SONIDO DE INICIO POKEMON GO(SLM)',
 'filesize': 19642323,
 'samplerate': None}

我已经尝试过了

mylist=[]
for loop
dict=create the dictionary
mylist.append(dict)

但是它给出了一个很长的错误。

如何将我的列表保存到.mat文件？预先感谢。

Answer 1

class A { public: A& operator=(A&& other){/*...*/}; }; int main() { A a; A b; a = b; return 0; } 为此提供了一个简单的帮助程序功能scipy。

scipy.io.savemat

请注意，import scipy # scipy is installed # ... generate mylist fname = "my_filename" # arbitrary filename scipy.io.savemat(fname, {"Data": mylist}) 需要一个字典，因此，如果仅通过制作示例中所示的一键值对字典，就必须将savemat改成字典。
