python - 使用将多个变量分配给Python对象

Question

我无法理解我应该在这里做什么。我需要使用 class Runner: 和 run() 方法创建一个对象。令我困惑的代码部分是这部分:

colorA,turtleA,yourName = objA.run()
colorB,turtleB,yourName = objB.run()

我希望得到一些关于如何完成这项工作的想法。我已经设置了一个简单的类(class)。这就是我所拥有的:

import turtle

class Runner:

    def __init__(self,color):
        self.color = color

    def run(self):
        self = turtle.Turtle(), "Michael Corbett"

完整的 Proj02 代码:

from Proj02Runner import Runner
import turtle

window = turtle.Screen()
turtle.setup(300,200)

objA = Runner("red") #create one object
objB = Runner("green") #create a second object
#Call the run method on each object and unpack
# the tuple that is returned.
colorA,turtleA,yourName = objA.run()
colorB,turtleB,yourName = objB.run()

window.title(yourName)

#Manipulate the turtles to draw a picture.
turtleA.left(90)
turtleA.stamp()
turtleA.right(90)
turtleA.forward(50)
turtleA.right(30)
turtleA.color(colorA)
turtleA.forward(50)

turtleB.right(180)
turtleB.forward(50)
turtleB.left(30)
turtleB.color(colorB)
turtleB.forward(50)

Answer 1

让你的run方法看起来像这样:

def run(self):
    return self.color, turtle.Turtle(), "Michael Corbett"
