import turtle

tina.penup()
tina.forward(20)
tina.write("Why, hello there, " + your_name + "!")
tina.backward(20)
tina.color("green")
tina.left(90)
tina.forward(100)
tina.right(90)

tina.dot(10)
tina.penup()
tina.goto(100, 100)
color = input("What color is the shape")
try:
  if color == ("red"):
    tina.write("Your are correct" + your_name + "!")
    tina.backward(20)
  elif color == ("green" or "Green"):
    tina.write("Sorry, It is actually Red")
    tina.backward(20)
  elif color == ("black" or "Black"):

    tina.backward(20)

    tina.write("Sorry, It is actually Red")
    tina.backward(20)
  elif color == ("blue" or "Blue"):
    tina.write("Sorry, It is actually Red")
    tina.backward(20)
except:
  tina.backward(20)
  tina.write("Sorry, but that isn't a color")
  tina.backward(20)

这是我的代码。我想知道如何让乌龟在整个程序中随机改变颜色。它应该在整个程序中每隔0.5秒改变一次颜色。我该怎么做我试图随机导入。这是为了学校作业。请帮助。

首先，您应该将代码分解为函数，例如：

def drawShape (myTurtle, turtleColor, shapeColor):
    myTurtle.penup()
    myTurtle.backward(20)
    myTurtle.color(turtleColor)
    myTurtle.left(90)
    myTurtle.forward(100)
    myTurtle.right(90)
    myTurtle.pendown()
    myTurtle.pencolor(shapeColor)
    myTurtle.forward(50)
    myTurtle.right(50)
    myTurtle.forward(50)
    myTurtle.right(100)
    myTurtle.forward(55)
    myTurtle.left(50)
    myTurtle.forward(55)
    myTurtle.penup()
    myTurtle.forward(30)
    myTurtle.pendown()
    myTurtle.dot(10)
    myTurtle.penup()
    myTurtle.goto(100, 100)

您可以使用random创建随机数：

import random
randomNumber = random.randint(0,5) #created random integer between 0 and 5

现在，为了对颜色使用随机值，首先创建一个颜色列表：

myColorList = ["red","green","black","purple","blue","yellow"]

然后创建一个随机整数，并将该整数用作此列表的索引。

查看答案时，您不需要那么多if。而是检查color in myColorList-如果不是，则报告 对不起，但这不是颜色

要根据计时器更改乌龟的颜色（或通常做某事），请使用turtle.ontimer()函数。调用ontimer时，会给它一个函数和一个代表毫秒的数字。 here是一个很好的例子。在此示例中，您可以看到他们在传递给ontimer的函数的末尾调用ontimer，这样它就不断发生，而不仅仅是一次。
