Question

我习惯使用Java但不熟悉Python，我试图让以下blob查找代码运行3次，增加每个分数并打印总分。

在Java中我会使用：

int totalScore = 0
for(int i=0; i<=3; i++)
    {
      blob code..;
      totalScore += score;
      i++
    }
System.out.println(totalScore);

如何将评分代码包装在执行3次的循环中，然后打印总分？任何帮助深表感谢。

from SimpleCV import *

def getscoreforrgb(rgb):
    return rgbmap[rgb] 

for score in range(3):


    blobsY = img1.findBlobs()
    if blobsY is not None:
        blobsY.sortArea()
        blobsY[-1].draw(Color.RED, width=3)
        y = blobsY[-1]
        print y


    blobsX = img1.findBlobs()
    if blobsX is not None:
        blobsX.sortArea()
        blobsX[-1].draw(Color.RED, width=3)
        x = blobsX[-1]
        print x

    colrgb =  pixcol[x2, y2]
    print colrgb
    score = getscoreforrgb(colrgb)

    total = 0
    totalScore = total + score

print totalScore

Answer 1

特别是，因为元素total的范围在循环内部并不是全局完成的，所以每次取值为0时，请尝试将其置于循环之外。

from SimpleCV import *
def getscoreforrgb(rgb):
    return rgbmap[rgb] 
total = 0
totalScore = 0
for score in range(3):


    blobsY = img1.findBlobs()
    if blobsY is not None:
        blobsY.sortArea()
        blobsY[-1].draw(Color.RED, width=3)
        y = blobsY[-1]
        print y


    blobsX = img1.findBlobs()
    if blobsX is not None:
        blobsX.sortArea()
        blobsX[-1].draw(Color.RED, width=3)
        x = blobsX[-1]
        print x

    colrgb =  pixcol[x2, y2]
    print colrgb
    score = getscoreforrgb(colrgb)

    totalScore = total + score

print totalScore

Answer 2

首先，在循环外定义var payload = {id: user.id}; var token = jwt.sign(payload, jwtOptions.secretOrKey);。然后，您只需更改

即可

totalScore

到

total = 0
totalScore = total + score

Python for循环将分数添加到总分
