用python画一朵玫瑰花

以下是使用turtle库绘制一朵玫瑰花的Python代码：

import turtle

# 设置画布和画笔
canvas = turtle.Screen()
pen = turtle.Turtle()

# 设置画笔的颜色和粗细
pen.color("red")
pen.pensize(2)

# 绘制玫瑰花的轮廓
pen.up()
pen.goto(0, 200)
pen.down()
pen.begin_fill()
pen.fillcolor("pink")
for i in range(200):
    pen.right(1)
    pen.forward(0.3)
pen.end_fill()

# 绘制玫瑰花的花瓣
for i in range(10):
    pen.up()
    pen.goto(0, 0)
    pen.setheading(0)
    pen.down()
    pen.begin_fill()
    pen.fillcolor("red")
    for j in range(50):
        pen.right(1)
        pen.forward(2)
    pen.left(120)
    for j in range(50):
        pen.right(1)
        pen.forward(2)
    pen.left(120)
    for j in range(50):
        pen.right(1)
        pen.forward(2)
    pen.end_fill()

# 隐藏画笔
pen.hideturtle()

# 显示绘制结果
canvas.mainloop()

该代码运行后将绘制一朵粉色的玫瑰花，花瓣为红色。可以根据需要调整颜色、粗细或其他参数来自定义绘制结果。
