Python绘制樱花树代码分享

Python绘制樱花树的部分代码如下：

import turtle as tu
import random as ra

def flower():
    tu.hideturtle()
    tu.pensize(2)
    tu.pencolor("pink")
    flowersize = ra.randint(1, 5)
    for j in range(5):
        tu.forward(int(flowersize))
        tu.backward(int(flowersize))
        tu.right(72)

def tree(n, k):
    tu.pendown()
    tu.pencolor("black")
    tu.pensize(n / 4)
    tu.forward(k)
    if n > 0:
        r = ra.random() * 10 + 10
        l = ra.random() * 10 + 10
        x = k * (ra.random() * 0.25 + 0.7)
        tu.right(r)
