Question

我试图让它出现在乌龟身上，但我一直在接受＆＃34; shape_color未定义＆＃34;第50行（倒数第二行）

如果我将其更改为box_color我

第14行，在新月中 t.circle（width，extent = 180，steps = none）
NameError：name＆＃39; none＆＃39;未定义

我不明白为什么其他人不会收到此错误，请帮忙。

import random
import turtle as t

def crescent(x, y, width, height, shape_color):
    t.fillcolor(shape_color)
    t.penup()
    t.goto(x, y)
    t.pendown()
    t.begin_fill()
    t.circle(width, extent=180, steps=none)
    t.endfill()
    t.penup()
    t.fillcolor("white")
    t.end_fill()
    t.penup()  
    t.fillcolor("white") 

def star(x, y, width, shape_color):
    t.fillcolor(shape_color)
    t.penup()
    t.goto(x, y)
    t.pendown()
    t.begin_fill()
    for s in range(5):
        t.forward(width)
        t.right(144)
    t.end_fill()
#--------------------------------------------------------------------

t.colormode(255)  
t.tracer(-1)


for n in range(10):
    x = random.randint(-200, 200)
    y = random.randint(-200, 200)

    r = random.randint(0, 255)
    g = random.randint(0, 255)
    b = random.randint(0, 255)
    box_color = (r, g, b)

    width  = random.randint(5, 50) 
    height = random.randint(5, 50) 

    crescent(x, y, width, height, box_color)
    star(x, y, width, height, shape_color)

Answer 1

我认为代码有两个检查点。首先，将t.fillcolor(white)更改为t.fillcolor("white")。

其次，将crescent(x, y, width, height, shape_color更改为crescent(x, y, width, height, box_color。因为你赋值变量box_color，而不是shape_color。它只是新月＆＃39;的参数。

Answer 2

Yoy有很多错误：

-

在for内star(x, y, width, height, shape_color)执行shape_color，但您没有取消shape_color = box_color star(x, y, width, height, shape_color)。你至少需要：

t.circle

-

在step=none中，您使用的是None，但必须是N，其上方为step=None。
但您也可以跳过step=None，默认情况下会使用t.circle(width, extent=180) 请参阅文档：turtle - circle

-

您忘了t.endfill()命令t.end_fill() - 它必须是star

-

函数def star(x, y, width, shape_color):需要4个参数for，但在star(x, y, width, height, shape_color)'. You have to remove循环中，您使用5个参数执行它shape_color = box_color star(x, y, width, shape_color) height`

import random
import turtle as t

def crescent(x, y, width, height, shape_color):
    t.fillcolor(shape_color)
    t.penup()
    t.goto(x, y)
    t.pendown()
    t.begin_fill()
    t.circle(width, extent=180)
    t.end_fill()
    t.penup()
    t.fillcolor("white")
    t.end_fill()
    t.penup()  
    t.fillcolor("white") 

def star(x, y, width, shape_color):
    t.fillcolor(shape_color)
    t.penup()
    t.goto(x, y)
    t.pendown()
    t.begin_fill()
    for s in range(5):
        t.forward(width)
        t.right(144)
    t.end_fill()

重复放置多边形时，您可能会考虑标记而不是绘图。在冲压时，我们为每个形状创建一个龟，它本身就具有这种形状。然后我们根据需要移动，着色和调整乌龟的大小，然后盖章。这有几个优点：速度;能够利用绘图不能的图形操作（如剪切）：

from random import randint, random
import turtle

SHAPE_SIZE = 20

def crescent(width):
    turtle.begin_poly()
    turtle.circle(width, extent=180)
    turtle.end_poly()

    return turtle.get_poly()

def star(width):
    turtle.begin_poly()
    for _ in range(5):
        turtle.forward(width)
        turtle.right(144)
    turtle.end_poly()

    return turtle.get_poly()

screen = turtle.Screen()
width, height = screen.window_width() / 2, screen.window_height() / 2

turtle.penup()  # use the 'default' turtle to create the other two turtles
turtle.hideturtle()
turtle.setheading(90)
turtle.speed('fastest')

screen.register_shape('crescent', crescent(SHAPE_SIZE))
crescent_turtle = turtle.Turtle('crescent', visible=False)
crescent_turtle.speed('fastest')
crescent_turtle.penup()

screen.register_shape('star', star(SHAPE_SIZE))
star_turtle = turtle.Turtle('star', visible=False)
star_turtle.speed('fastest')
star_turtle.penup()

for _ in range(25):
    x, y = randint(-width, width), randint(-height, height)

    r, g, b = random(), random(), random()
    shape_color = (r, g, b)

    size = randint(5, 50)

    heading = [0, 180][randint(0, 1)]

    for tortoise in [crescent_turtle, star_turtle]:
        tortoise.turtlesize(SHAPE_SIZE / size, outline=1)
        tortoise.setheading(heading)
        tortoise.color(shape_color)
        tortoise.goto(x, y)
        tortoise.stamp()

screen.exitonclick()

在某些方面，它可以简化逻辑（将我对star()和crescent()的定义与其他解决方案进行比较。）它也有其局限性，例如我们需要使用简单的多边形。

我的乌龟代码有一个错误，我似乎无法修复它的结尾
