python樱花树代码大全

以下是一个绘制樱花树的Python代码示例：

import turtle
import random

def draw_tree(t, branch_len):
    angle = random.randint(22, 30)
    sf = random.uniform(0.6, 0.8)
    
    if branch_len < 5:
        t.color("green")
    else:
        t.color("brown")
    
    if branch_len > 15:
        t.pensize(int(branch_len / 10))
    else:
        t.pensize(2)
    
    if branch_len > 3:
        t.forward(branch_len)
        t.right(angle)
        draw_tree(t, branch_len * sf)
        t.left(angle * 2)
        draw_tree(t, branch_len * sf)
        t.right(angle)
        t.backward(branch_len)

def draw_sakura():
    window = turtle.Screen()
    window.bgcolor("white")

    t = turtle.Turtle()
    t.speed(0)
    t.up()
    t.goto(0, -200)
    t.down()
    
    draw_tree(t, 100)
    
    window.exitonclick()

draw_sakura()
