一、前言
圣诞节快到了，是不是想用python画一个可爱的圣诞树，我在各大网站都查了一下，都不太美观，然后我就学习了一下别人的代码改写了一下，自己加了一些东西，弄的好看一些了，给大家开源出来，欢迎大家指正学习，也欢迎转载，请注明出处哦~
二、创意名
这个圣诞你很快乐，因为由我为你亲手绘制的圣诞树。
三、效果展示
四、实现步骤
一、Turtle是什么？
Turtle库是Python语言中一个很流行的绘制图像的函数库，想象一个小乌龟，在一个横轴为x、纵轴为y的坐标系原点，(0,0)位置开始，它根据一组函数指令的控制，在这个平面坐标系中移动，从而在它爬行的路径上绘制了图形。
1.引入库
from turtle import * from random import * import math2.turtle绘图的基础知识
(1) 画笔运动命令
(2) 画笔控制命令
(3) 全局控制命令
五、编码实现
完整代码如下所示：
from turtle import * from random import * import math # 绘图方法 def Rightdraw(Range, Fd, Right): for i in range(Range): # Range循环次数 fd(Fd) # 向前Fd个距离 right(Right) # 在当前行进方向再向右偏转Right度 def Leftdraw(Range, Fd, Left): for i in range(Range): # Range循环次数 fd(Fd) # 向前Fd个距离 left(Left) # 在当前行进方向再向右偏转Right度 # 背景改为黑色 screensize(bg='black') # 重设海龟位置 def changeMypos(x, y, range=heading(), Fd=0): penup() goto(x, y) seth(range) fd(Fd) pendown() def drawBranch(x, y, size=1): changeMypos(x, y) Leftdraw(6, 3, 9) seth(0) Rightdraw(6, 3, 9) seth(0) fd(6) # 画五角星 def drawStar(x, y, Range, size): pensize(1) color("red", "yellow") begin_fill() changeMypos(x, y, Range) for i in range(5): # 画五角星 forward(10 * size) right(144) # 五角星的角度 forward(10 * size) left(72) # 继续换角度 end_fill() right(126) # 绘制雪花 def drawSnow(): hideturtle() speed(0) pencolor("white") pensize(2) for i in range(100): # 雪花数量 changeMypos(randint(-248, 248), randint(-100, 248)) petalNumber = 6 # 雪花花瓣数为6 snowSize = int(randint(2, 10)) for j in range(petalNumber): fd(snowSize) backward(snowSize) right(360 / petalNumber) # 圣诞袜子 def drawSock(x, y, range, size=1): # 绘制袜子的白边 pensize(1) changeMypos(x, y, range) color("black", "white") begin_fill() fd(20 * size) circle(3 * size, 180) fd(20 * size) circle(3 * size, 180) end_fill() # 绘制袜子的下半部分 color("white", "red") begin_fill() startx = x + 2 * size * math.cos(math.radians(range)) starty = y + 2 * size * math.sin(math.radians(range)) finalx = x + 18 * size * (math.cos(math.radians(range))) finaly = y + 18 * size * (math.sin(math.radians(range))) changeMypos(startx, starty, range -
