Question

我在完成作业时遇到问题，我绝不会找人为我做作业。我们的教授没有回答或提供足够的资源来解决我们的任务问题。我复制了一个给我们的示例代码，但我无法让它本身运行。

当我运行这个程序时，我在命令行中收到的所有内容都是省略号而没有别的有没有人知道省略号是什么意思？ My code and command line screenshot Screenshot of my example code

附件将是代码：

def encode(msgPic,original):
 # Assume msgPic and original have same dimensions
 # First, make all red pixels even
 for pxl in getPixels(original):
  # Using modulo operator to test oddness
  if (getRed(pxl) % 2) == 1:
   setRed(pxl, getRed(pxl) - 1)
 # Second, wherever there???s black in msgPic
 # make odd the red in the corresponding original pixel
 for x in range(0,getWidth(original)):
  for y in range(0,getHeight(original)):
   msgPxl = getPixel(msgPic,x,y)
   origPxl = getPixel(original,x,y)
   if (distance(getColor(msgPxl),black) < 100.0):
     # It's a message pixel! Make the red value odd.
     setRed(origPxl, getRed(origPxl)+1)

以下是示例提示输入命令行的代码：

- beach = makePicture(getMediaPath("beach.jpg"))  
- explore(beach)"  
- msg = makePicture(getMediaPath("msg.jpg"))  
- encode(msg,beach)  
- explore(beach)  
- writePictureTo(beach,getMediaPath("beachHidden.png"))
