这篇教程Python——画一棵漂亮的樱花树(不同种樱花+玫瑰+圣诞树喔)写得很实用,希望能帮到您。 one 樱花树
动态生成樱花 效果图(这个是动态的): 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 t = T.Turtle() # 画布大小 w = T.Screen() t.hideturtle() # 隐藏画笔 t.getscreen().tracer(5, 0) w.screensize(bg='wheat') # wheat小麦 t.left(90) t.up() t.backward(150) t.down() t.color('sienna')
# 画樱花的躯干 Tree(60, t) # 掉落的花瓣 Petal(200, t) w.exitonclick()
飘落效果 效果图: 代码: from turtle import * from random import * from math import *
def tree(n,l): pd()#下笔 #阴影效果 t = cos(radians(heading()+45))/8+0.25 pencolor(t,t,t) pensize(n/3) forward(l)#画树枝
if n>0: b = random()*15+10 #右分支偏转角度 c = random()*15+10 #左分支偏转角度 d = l*(random()*0.25+0.7) #下一个分支的长度 #右转一定角度,画右分支 right(b) tree(n-1,d) #左转一定角度,画左分支 left(b+c) tree(n-1,d) #转回来 right(c) else: #画叶子 right(90) n=cos(radians(heading()-45))/4+0.5 pencolor(n,n*0.8,n*0.8) circle(3) left(90) #添加0.3倍的飘落叶子 if(random()>0.7): pu() #飘落 t = heading() an = -40 +random()*40 setheading(an) dis = int(800*random()*0.5 + 400*random()*0.3 + 200*random()*0.2) forward(dis) setheading(t) #画叶子 pd() right(90) n = cos(radians(heading()-45))/4+0.5 pencolor(n*0.5+0.5,0.4+n*0.4,0.4+n*0.4) circle(2) left(90) pu() #返回 t=heading() setheading(an) backward(dis) setheading(t) pu() backward(l)#退回
