用python的turtle实现玫瑰花的绘制

下面是使用 Python 的 turtle 模块绘制玫瑰花的代码：

import turtle

# 设置画笔
turtle.speed(0)
turtle.bgcolor("black")
turtle.color("white", "red")
turtle.penup()
turtle.goto(0, 0)
turtle.pendown()

# 绘制玫瑰花瓣
for i in range(200):
    turtle.right(1)
    turtle.forward(2)

turtle.left(140)
for i in range(200):
    turtle.right(1)
    turtle.forward(2)

# 绘制玫瑰花叶
turtle.speed(0)
turtle.penup()
turtle.goto(-150, -150)
turtle.pendown()
turtle.color("white", "green")
turtle.begin_fill()
turtle.left(120)
turtle.forward(50)
for i in range(10):
    turtle.right(15)
    turtle.forward(20)
    turtle.left(30)
    turtle.forward(20)
    turtle.right(15)
    turtle.forward(50)
    turtle.left(157)
turtle.end_fill()

turtle.penup()
turtle.goto(150, -150)
turtle.pendown()
turtle.begin_fill()
turtle.right(120)
turtle.forward(50)
for i in range(10):
    turtle.left(15)
    turtle.forward(20)
    turtle.right(30)
    turtle.forward(20)
    turtle.left(15)
    turtle.forward(50)
    turtle.right(157)
turtle.end_fill()

# 隐藏画笔
turtle.hideturtle()

# 显示绘图窗口
turtle.done()

运行以上代码，即可绘制出一朵美丽的玫瑰花。你可以尝试修改代码，调整花瓣和叶子的形状、颜色等参数，创造出更多不同的玫瑰花效果。
