利用turtle库绘制樱花

利用turtle库绘制樱花的代码如下：

import turtle as t
import random

# 绘制花瓣
def petal():
    t.pencolor(random.uniform(0.5, 1), random.uniform(0, 0.5), random.uniform(0.5, 1))
    t.fillcolor(random.uniform(0.5, 1), random.uniform(0, 0.5), random.uniform(0.5, 1))
    t.begin_fill()
    for i in range(6):
        t.forward(30)
        t.right(60)
        t.forward(30)
        t.right(120)
    t.end_fill()

# 绘制花朵
def flower(pos):
    t.penup()
    t.goto(pos[0], pos[1])
    t.pendown()
    petal_num = random.randint(6, 12)
    for i in range(petal_num):
        t.right(360 / petal_num)
        petal()

# 绘制樱花
def sakura():
    t.bgcolor('#F781BE')
    t.speed('fastest')
    pos_list = []
    for i in range(8):
        x = random.uniform(-t.window_width() / 2, t.window_width() / 2)
        y = random.uniform(-t.window_height() / 2, t.window_height() / 2)
        pos_list.append((x, y))
    for pos in pos_list:
        flower(pos)
    t.done()

# 绘制樱花
sakura()
