樱花树

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()
