如何在蟒蛇龟中绘制填充矩形

Question

import turtle
def penup():
for x in drawings:
x.penup()
penup()
def drawgrass():
for x in range(10):
grass.goto(300,300)
grass.color("green")
grass.begin_fill()
grass.forward(200)
grass.left(300)
grass.forward(200)
grass.left(300)
grass.end_fill()

penup()
drawgrass()

所以我正在创建这个程序，它将创造某种景观，我正在努力制作草地。我想把光标放在300300，然后画一个巨大的矩形，然后把它填充成绿色。到目前为止，我无法使矩形工作，也无法使其覆盖整个屏幕的下半部分。有人能帮帮我吗？

与您的另一个问题一样，您的penup()函数毫无意义。以下是我如何用绿色填充一半屏幕的方法：

from turtle import Screen, Turtle
def drawgrass():
grass.color("green")
width, height = screen.window_width(), screen.window_height()
grass.penup()
grass.goto(-width/2, 0)
grass.pendown()
grass.begin_fill()
for _ in range(2):
grass.forward(width)
grass.right(90)
grass.forward(height/2)
grass.right(90)
grass.end_fill()
screen = Screen()
grass = Turtle()
grass.speed('fastest')  # because I have no patience
drawgrass()
grass.hideturtle()
screen.exitonclick()

但我真正想做的是盖章它：

from turtle import Screen, Turtle
CURSOR_SIZE = 20
def drawgrass():
grass.color('green')
grass.shape('square')
width, height = screen.window_width(), screen.window_height()
grass.penup()
grass.goto(0, -height/4)
grass.shapesize(height/2 / CURSOR_SIZE, width / CURSOR_SIZE)
grass.stamp()
screen = Screen()
grass = Turtle()
grass.hideturtle()
drawgrass()
screen.exitonclick()
