python 绘制红色的玫瑰花

以下是使用Python的Turtle库绘制一朵红色的玫瑰花的示例代码：

import turtle

# 设置画布和画笔
canvas = turtle.Screen()
canvas.bgcolor("black")
pen = turtle.Turtle()
pen.speed(0)
pen.color("red")

# 绘制花朵
for i in range(10):
    pen.circle(100)
    pen.right(36)

# 绘制花瓣
for i in range(12):
    pen.penup()
    pen.setposition(0, 0)
    pen.pendown()
    pen.left(i * 30)
    pen.forward(150)
    pen.right(90)
    pen.begin_fill()
    pen.circle(20, 180)
    pen.left(90)
    pen.circle(20, 180)
    pen.end_fill()

# 绘制花蕾
pen.penup()
pen.setposition(0, 0)
pen.pendown()
pen.color("green")
pen.begin_fill()
pen.circle(50)
pen.end_fill()

# 隐藏画笔
pen.hideturtle()

# 关闭画布
canvas.exitonclick()

运行上述代码，将会绘制出一朵红色的玫瑰花。你可以根据自己的喜好调整花朵和花瓣的颜色和大小。
