Question

我正在写一个多行文件，像这样的行：

 func data() -> Data {
 var imageData = UIImagePNGRepresentation(self) 
// Resize the image if it exceeds the 2MB API limit
 if (imageData?.count)! > 2097152 {
   let oldSize = self.size
   let newSize = CGSize(width: 800, height: oldSize.height / oldSize.width * 
 800)
   let newImage = self.resizeImage(self, size: newSize)
   imageData = UIImageJPEGRepresentation(newImage, 0.7)
   }
   return imageData!
 }

在某些情况下，当我使用以下命令时，我需要使用一个包含文件路径的变量：

     @IBOutlet weak var thumbImg: UIImageView!
     let picture = Image()
     let imageDownSizing = thumbImg.image?.data()

     //thumbImg.image is of type UIImage type, so convert UIImage -> Data. 
     //picture.image is of type Data. 
     picture.image = UIImagePNGRepresentation(thumbImg.image!)
     picture.image = imageDownSizing

     let item = Item()
     item.toImage = picture

       do{
            let realm = try! Realm()
            try realm.write {
                realm.add(item)
            }
        }catch{
            print("Error saving context \(error)")
        }

结果：

workspace -fr "fluidCache" "cache/nCache/fluid";

我需要的结果是带有引号的render_output：

render_output = os.path.join(project_root, r'common\render_output')
ws_file.write("""workspace -fr "images" {0};""".format(render_output))

我应该如何设置render_output的格式，以便在三引号的write参数中保留其字符串值的引用？

Answer 1

ws_file.write("""workspace -fr "images" "{0}";""".format(render_output))

如何在.format期间保留字符串的引号
