为什么要画樱花

今天，我在路边看到了一颗樱花树。从侧面看去他是异常的美丽。
所以我们今天就用turtle来画樱花树吧！

所需模块

需要的库

import turtle import random import time 

需要的模块

turtle.setheading() #快速绘图 turtle.forward() #向当前画笔方向移动distance像素长 turtle.backward() #向当前画笔相反方向移动distance像素长度 turtle.left() #逆时针移动 turtle.right() #顺时针移动 turtle.penup() #移动时不绘制图形,提起笔，用于另起一个地方绘制时用 turtle.pendown() #移动时绘制图形,缺省时也为绘制 turtle.fillcolor() #绘制图形的填充颜色 turtle.end_fill() #填充完成 turtle.begin_fill() #准备开始填充图形 turtle.circle() #以给定半径画圆 turtle.goto() #将画笔移动到坐标为x,y的位置 turtle.tracer() #追踪运行轨迹 turtle.hideturtle()	 #隐藏箭头显示 turtle.pensize() #绘制图形时的宽度  

樱花树的躯干

# 画樱花的躯干(60,turtle) def Tree(branch, turtle):     time.sleep(0.0005)     if branch > 3:         if 8 <= branch <= 12:             if random.randint(0, 2) == 0:                 turtle.color('snow')              else:                 turtle.color('lightcoral')               turtle.pensize(branch / 3)         elif branch < 8:             if random.randint(0, 1) == 0:                 turtle.color('snow')             else:                 turtle.color('lightcoral')               turtle.pensize(branch / 2)         else:             turtle.color('sienna')               turtle.pensize(branch / 10)  # 6         turtle.forward(branch)         a = 1.5 * random.random()         turtle.right(20 * a)         b = 1.5 * random.random()         Tree(branch - 10 * b,turtle)         turtle.left(40 * a)         Tree(branch - 10 * b, turtle)         turtle.right(20 * a)         turtle.up()         turtle.backward(branch)         turtle.down()  

掉落的花般

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

运行部分

turtle.hideturtle()  # 隐藏画笔 turtle.getscreen().tracer(5, 0) #w.screensize(bg='wheat')   wheat小麦 turtle.left(90) turtle.up() turtle.backward(150) turtle.down() turtle.color('sienna') # 树干 Tree(60, turtle) # 掉落的花瓣 Petal(200, turtle) w.exitonclick()
