用pytuon帮我写一个玫瑰花代码

以下是一个简单的Python玫瑰花代码：

import turtle

def draw_petal(turtle, radius):
    turtle.circle(radius, 60)
    turtle.left(120)
    turtle.circle(radius, 60)

def draw_flower(turtle, petal_radius, petal_num):
    for i in range(petal_num):
        draw_petal(turtle, petal_radius)
        turtle.left(360 / petal_num)

def draw_stem(turtle, stem_length):
    turtle.right(90)
    turtle.forward(stem_length)

def draw_leaf(turtle, leaf_size):
    turtle.right(90)
    turtle.forward(leaf_size)
    turtle.right(120)
    turtle.forward(leaf_size)
    turtle.right(120)
    turtle.forward(leaf_size)
    turtle.right(180)
    turtle.forward(leaf_size)
    turtle.right(60)
    turtle.forward(leaf_size)
    turtle.right(60)

def draw_rose(turtle, petal_radius, petal_num, stem_length, leaf_size):
    draw_flower(turtle, petal_radius, petal_num)
    draw_stem(turtle, stem_length)
    draw_leaf(turtle, leaf_size)

if __name__ == '__main__':
    window = turtle.Screen()
    window.bgcolor("white")
    window.title("Rose")

    rose = turtle.Turtle()
    rose.color("red")
    rose.speed(10)
    rose.penup()
    rose.goto(0, -150)
    rose.pendown()

    draw_rose(rose, 100, 12, 200, 50)

    window.exitonclick()

可以根据需要调整玫瑰花的大小和形状。
