復制Python后的串列更改

我正在撰寫集群程式的最后一部分，我想決議一個像

--
COLOR
-
POINT COLOR
...

在哪里

COLOR = (R,G,B)
POINT = (X,Y)

例子：

--
(255,0,4)
-
(0,0) (255,0,4)
(0,1) (255,0,4)
(0,2) (255,0,4)
(0,3) (255,0,4)
--
(32,32,12)
-
(1,0) (156,0,42)
(1,1) (156,0,42)
(1,2) (156,0,42)
(1,3) (156,0,42)

我想將所有這些資訊保存在不同的類中，以便更輕松地處理資料。

這是我在python中的代碼：

#!/usr/bin/env python3

import sys

class Point:
    def __init__(self, x, y):
        self.x = x
        self.y = y

class Color:
    def __init__(self, r, g, b):
        self.r = r
        self.g = g
        self.b = b

class Pixel:
    def __init__(self, point, color):
        self.point = point
        self.color = color

class Cluster:
    def __init__(self, meanColor, pixels):
        self.meanColor = meanColor
        self.pixels = pixels

def printCluster(cl):
    print("---------------")
    print("("   str(cl.meanColor.r)   ","   str(cl.meanColor.g)   ","   str(cl.meanColor.b)   ")")
    print("I have "   str(len(pixels))   " pixels.")
    for px in pixels:
        print("("   str(px.point.x)   ","   str(px.point.y)   ") ("   str(px.color.r)   ","   str(px.color.g)   ","   str(px.color.b)   ")")

def printClusters(clusters):
    for cl in clusters:
        printCluster(cl)

def getColor(line):
    r = int(line.split(',')[0][1:])
    g = int(line.split(',')[1])
    b = int(line.split(',')[2][:-1])
    color = Color(r,g,b)
    return (color)


file = open(sys.argv[1], 'r')

meanColor = None
clusters = []
cluster = ""
pixels = []

import copy

count = 0
file.readline()
line = file.readline().rstrip('\n')
meanColor = getColor(line)
file.readline()
while True:
    count  = 1
    line = file.readline().rstrip('\n')
    if (line == "--"):
        pixelsCopy = list(pixels)
        cluster = Cluster(meanColor, pixelsCopy)
        printClusters(clusters)
        printCluster(cluster)
        clusters.append(cluster)
        pixels = []
        printCluster(cluster)
        line = file.readline().rstrip('\n')
        meanColor = getColor(line)
        file.readline()
    elif (line and line != "--"):
        print("-------------------------------")
        printClusters(clusters)
        print("line: ~"   line   "~")
        x = int(line.split()[0].split(',')[0][1:])
        y = int(line.split()[0].split(',')[1][:-1])
        print("x: "   str(x))
        print("y: "   str(y))
        point = Point(x,y)
        r = int(line.split()[1].split(',')[0][1:])
        g = int(line.split()[1].split(',')[1])
        b = int(line.split()[1].split(',')[2][:-1])
        print("r: "   str(r))
        print("g: "   str(g))
        print("b: "   str(b))
        color = Color(r,g,b)
        pixels.append(Pixel(point, color))
    if not line:
        pixelsCopy = list(pixels)
        cluster = Cluster(meanColor, pixelsCopy)
        clusters.append(cluster)
        #printCluster(cluster)
        break

printClusters(clusters)

出于某種原因，在 while 回圈之后，當我列印所有集群物件時，我看到所有物件都包含相同的像素串列，我嘗試使用 deepcopy、[:] 和 list() 進行復制，但沒有任何意義。我不知道我的錯誤在哪里，我也在重置為 [] 后列印集群，我看到它像參考串列一樣保存，但我不知道為什么我使用 list() 來制作副本。

謝謝！

uj5u.com熱心網友回復：

您需要集群實體的名為像素的屬性：

def printCluster(cl):
    print("---------------")
    print("("   str(cl.meanColor.r)   ","   str(cl.meanColor.g)   ","   str(cl.meanColor.b)   ")")
    print("I have "   str(len(pixels))   " pixels.")
    for px in cl.pixels:
        print("("   str(px.point.x)   ","   str(px.point.y)   ") ("   str(px.color.r)   ","   str(px.color.g)   ","   str(px.color.b)   ")")
