Python——画一棵漂亮的樱花树(不同种樱花+玫瑰+圣诞树喔)

·  阅读 309

最近翻到有不少用Python(大多是turtle库)绘制的树图,感觉很漂亮,我整理了一下,挑了一些我觉得不错的代码分享给大家(这些我都测试过,确实可以生成喔~) one 樱花树

动态生成樱花

效果图(这个是动态的):

image.png 实现代码

import turtle as T

import random

import time

# 画樱花的躯干(60,t)
def Tree(branch, t):

time.sleep(0.0005)
if branch > 3:
    if 8 <= branch <= 12:
        if random.randint(0, 2) == 0:
            t.color('snow')  # 白
        else:
            t.color('lightcoral')  # 淡珊瑚色
        t.pensize(branch / 3)
    elif branch < 8:
        if random.randint(0, 1) == 0:
            t.color('snow')
        else:
            t.color('lightcoral')  # 淡珊瑚色
        t.pensize(branch / 2)
    else:
        t.color('sienna')  # 赭(zhě)色
        t.pensize(branch / 10)  # 6
    t.forward(branch)
    a = 1.5 * random.random()
    t.right(20 * a)
    b = 1.5 * random.random()
    Tree(branch - 10 * b, t)
    t.left(40 * a)
    Tree(branch - 10 * b, t)
    t.right(20 * a)
    t.up()
    t.backward(branch)
    t.down()

# 掉落的花瓣
def Petal(m, t):

for i in range(m):
    a = 200 - 400 * random.random()
    b = 10 - 20 * random.random()
    t.up()
    t.forward(b)
    t.left(90)
    t.forward(a)
    t.down()
    t.color('lightcoral')  # 淡珊瑚色
    t.circle(1)
    t.up()
    t.backward(a)
    t.right(90)
    t.backward(b)

# 绘图区域

# 画布大小

t.hideturtle()  # 隐藏画笔

t.getscreen().tracer(5, 0)

w.screensize(bg='wheat')  # wheat小麦

t.color('sienna')

# 画樱花的躯干
