python绘画樱花树

可以使用Python的turtle库来绘制樱花树，以下是一个简单的示例代码：

import turtle
import random

def tree(branchLen, t):
    if branchLen > 5:
        angle = random.randint(20, 30)
        sf = random.uniform(0.6, 0.8)
        t.pensize(branchLen / 10)
        t.forward(branchLen)
        t.right(angle)
        tree(branchLen * sf, t)
        t.left(angle * 2)
        tree(branchLen * sf, t)
        t.right(angle)
        t.backward(branchLen)

def petal(t):
    for i in range(200):
        radius = random.randint(20, 50)
        x = random.randint(-300, 300)
        y = random.randint(-200, 200)
        t.penup()
        t.goto(x, y)
        t.pendown()
        red_amount = random.randint(50, 100) / 100.0
        blue_amount = random.randint(50, 100) / 100.0
        green_amount = random.randint(50, 100) / 100.0
        t.fillcolor((red_amount, blue_amount, green_amount))
        t.begin_fill()
        t.circle(radius)
        t.end_fill()

def main():
    t = turtle.Turtle()
    myWin = turtle.Screen()
    t.left(90)
    t.up()
    t.backward(200)
    t.down()
    t.color("brown")
    tree(100, t)
    petal(t)
    myWin.exitonclick()

main()
