python画图代码圣诞树

好的，以下是一个简单的 Python 代码来画一棵圣诞树：

# 导入必要的库
import turtle

# 初始化窗口
window = turtle.Screen()
window.bgcolor("white")
window.title("A Christmas Tree")

# 设置画笔
pen = turtle.Turtle()
pen.speed(0)
pen.color("green")
pen.penup()
pen.goto(0, -200)
pen.pendown()

# 画圣诞树的三角形部分
def draw_triangle(length, angle):
    pen.forward(length)
    pen.right(angle)
    pen.forward(length)
    pen.right(180-angle)
    pen.forward(length)
    pen.right(angle)
    pen.forward(length)

pen.begin_fill()
draw_triangle(100, 75)
pen.end_fill()

pen.begin_fill()
draw_triangle(75, 75)
pen.end_fill()

pen.begin_fill()
draw_triangle(50, 75)
pen.end_fill()

# 绘制树干
pen.color("brown")
pen.right(90)
pen.forward(50)
pen.right(180)
pen.forward(50)

# 等待退出
window.exitonclick()

希望这可以帮到你。
