Question

我正在用Python编写代码，以在特定目录（包括其子目录）中列出所有文件及其大小和创建日期。我最终得到的代码仅适用于当前目录，而不适用于特定目录。如果我将变量文件夹的值替换为特定目录，则会出现错误。

下面是我的代码：

class myAnnotation: MKPointAnnotation {
    var objectId:String = ""
    var myImage:String = ""
}

//annotation for the points
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {

    guard annotation is myAnnotation else { return nil }
    let myAnnotation = annotation as! myAnnotation
    let identifier = "annotationView"
    var annotationView = mapView.dequeueReusableAnnotationView(withIdentifier: identifier)
    print (myAnnotation.myImage)
    if annotationView == nil {
        var annotationView = mapView.dequeueReusableAnnotationView(withIdentifier: identifier)
        annotationView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: identifier)
    }

    //Pin with Title

    if annotation.title == "fire"  {
        annotationView?.image = UIImage(named: "fire")
    } else if annotation.title == "water"{
        annotationView?.image = UIImage(named: "water")
    }

    return annotationView
}

func addStickForDanger(_ title:String, report:Reports){
    let droPin = myAnnotation()
    if (report.type!).boolValue {
        droPin.title = "fire"
    } else {
        droPin.title = "water"
    }
    droPin.coordinate = CLLocationCoordinate2DMake(CLLocationDegrees(truncating: report.lat!), CLLocationDegrees(truncating: report.lon!))
    droPin.objectId = report.objectId!

    myMap.addAnnotation(droPin)
}

对于特定目录，您需要将根路径与文件路径连接起来以获得完整路径。

for root, dirs, files in os.walk(folder):
for list in files:
    list=os.path.join(root,list) # joining root and the file name for full path
    file_size = os.path.getsize(list)
    createDate = time.ctime(os.path.getctime(list))
    listOfFiles = list, "Size: %.1f bytes"%file_size, "Created date: " + createDate
    print(listOfFiles)

如何在特定目录（包括其子目录）中列出所有文件及其大小和创建日期？
