Python绘鼠，“福鼠”中华

编程应用、实战教程，不容错过
今天是正月初九，肺炎疫情依旧肆虐、形势依然严重，感谢所有为疫情一直在奔波、付出的人们。在此也希望大家用严实的防护措施，为打赢这场战役贡献自己的力量。
turtle库是一个很经典的绘图库，其最初来自于1967年创造的logo编程语言，之后被Python编写放到了Python的内置模块中。网络上有很多借助于turtle绘制精美图像的案例。比如小猪佩奇、皮卡丘、柯基犬等等。趁着新年假期还未结束，今天州的先生（https://zmister.com）为大家带来一个福鼠的绘制。
一、绘制鼠头
首先，咱们（https://zmister.com）把鼠的头给绘制了。鼠头主要是由圆来构成，脸庞是一个大圆，耳朵、眉毛、眼睛、嘴角和鼻子也都是由不同弧度的圆构成。鼠头的绘制代码如下所示：
def head():
turtle.color('black')
# 脸轮廓
turtle.pd() # 落笔
turtle.circle(50) # 画一个半径为50的圆
turtle.pu() # 提笔
# 右耳轮廓
turtle.goto(50,60) # 移动到x=50,y=60的位置
turtle.pd() # 落笔
turtle.circle(30,260) # 画一个半径为30，角度为245的圆弧
turtle.pu() # 提笔
# 右耳耳纹
turtle.goto(30,90)
turtle.pd()
turtle.seth(65)
turtle.circle(-30,70)
turtle.pu()
# 左耳轮廓
turtle.goto(-50,60)
turtle.pd()
turtle.seth(180) # 设置方向为西，
turtle.circle(-30,260)
turtle.pu()
# 左耳耳纹
turtle.goto(-30,90)
turtle.pd()
turtle.seth(120)
turtle.circle(30,70)
turtle.pu()
# 面部五官
# 右侧眉毛
turtle.goto(5,80)
turtle.seth(20)
turtle.pd()
turtle.circle(-25,40)
turtle.pu()
# 左侧眉毛
turtle.goto(-5,80)
turtle.seth(160)
turtle.pd()
turtle.circle(25,40)
turtle.pu()
# 右侧眼睛
turtle.begin_poly()
turtle.goto(8,60)
turtle.seth(45)
turtle.pd()
turtle.circle(-15,120)
turtle.pu()
turtle.goto(8,60)
turtle.seth(40)
turtle.pd()
turtle.circle(-15,100)
turtle.pu()
turtle.end_poly()
# 左侧眼睛
turtle.goto(-8,60)
turtle.seth(135)
turtle.pd()
turtle.circle(15,120)
turtle.pu()
turtle.goto(-8,60)
turtle.seth(140)
turtle.pd()
turtle.circle(15,100)
turtle.pu()
# 鼻子
# 鼻子上瓣
turtle.goto(-6,45)
turtle.seth(70)
turtle.pd()
turtle.circle(-6,150)
turtle.pu()
# 鼻子下瓣
turtle.goto(-6,45)
turtle.seth(-70)
turtle.pd()
turtle.circle(6,150)
turtle.pu()
# 鼻线
turtle.goto(0,40)
turtle.seth(270)
turtle.pd()
turtle.forward(7)
turtle.pu()
# 上嘴线
turtle.seth(200)
turtle.pd()
turtle.circle(-15,60)
turtle.pu()
turtle.goto(0,33)
turtle.seth(-20)
turtle.pd()
turtle.circle(15,60)
turtle.pu()
# 下嘴线
turtle.goto(10,33)
turtle.seth(260)
turtle.pd()
turtle.circle(-15,65)
turtle.pu()
turtle.goto(-10,33)
turtle.seth(280)
turtle.pd()
turtle.circle(15,65)
turtle.pu()
# 牙齿
turtle.goto(4,33)
turtle.seth(270)
turtle.pd()
turtle.forward(4)
turtle.seth(180)
turtle.forward(8)
turtle.seth(90)
turtle.forward(4)
turtle.pu()
# 胡须
turtle.pensize(2)
turtle.goto(30,30)
turtle.seth(8)
turtle.pd()
turtle.circle(-60,40)
turtle.pu()
turtle.goto(30,25)
turtle.seth(-5)
turtle.pd()
turtle.circle(-60,40)
turtle.pu()
turtle.goto(-30,30)
turtle.seth(172)
turtle.pd()
turtle.circle(60,40)
turtle.pu()
turtle.goto(-30,25)
turtle.seth(188)
turtle.pd()
turtle.circle(60,40)
turtle.pu()
# 睫毛
turtle.pensize(1)
turtle.goto(30,58)
turtle.seth(20)
turtle.pd()
turtle.circle(20,20)
turtle.pu()
turtle.pensize(1)
turtle.goto(28,62)
turtle.seth(25)
turtle.pd()
turtle.circle(20,12)
turtle.pu()
turtle.pensize(1)
turtle.goto(-30,58)
turtle.seth(160)
turtle.pd()
turtle.circle(-20,20)
turtle.pu()
turtle.pensize(1)
turtle.goto(-28,62)
turtle.seth(165)
turtle.pd()
turtle.circle(-20,12)
turtle.pu()运行上述代码，我们可以看到鼠头可以完整地绘制出来了，如下动图所示：
二、绘制身体
接着，咱们来绘制老鼠的身体。我们（https://zmister.com）画的这个老鼠是一个穿着财神服站立拱手的老鼠，所以它的身体需要重点突出的是服装：
def body():
# 左手
turtle.goto(-25,8)
turtle.seth(240)
turtle.pd()
turtle.circle(150,15)
turtle.seth(270)
turtle.circle(40,15)
turtle.circle(15,65)
turtle.seth(0)
turtle.forward(10)
turtle.circle(10,100)
turtle.seth(90)
turtle.forward(5)
turtle.circle(10,100)
turtle.seth(180)
turtle.forward(10)
turtle.pu()
# 右手
turtle.goto(25,8)
turtle.seth(-60)
turtle.pd()
turtle.circle(-150,15)
turtle.seth(270)
turtle.circle(-40,15)
turtle.circle(-15,65)
turtle.seth(180)
turtle.forward(10)
turtle.circle(-10,100)
turtle.seth(90)
turtle.forward(5)
turtle.circle(-10,100)
turtle.seth(0)
turtle.forward(10)
turtle.pu()
# 袍子
turtle.goto(-30,-48)
turtle.seth(270)
turtle.pd()
turtle.forward(30)
turtle.circle(10,100)
turtle.seth(0)
turtle.forward(38)
turtle.circle(10,100)
turtle.seth(90)
turtle.forward(30)
turtle.pu()
# 领口
turtle.goto(-20,4)
turtle.pd()
turtle.seth(300)
turtle.circle(30,20)
turtle.seth(0)
turtle.forward(25)
turtle.seth(30)
turtle.circle(30,20)
turtle.pu()
# 官带
turtle.goto(-7,-38)
turtle.seth(0)
turtle.pd()
turtle.forward(15)
turtle.pu()
turtle.goto(-30,-54)
turtle.pd()
turtle.forward(60)
turtle.pu()
# 袍子上的波浪
turtle.goto(-30,-80)
turtle.pd()
turtle.seth(90)
turtle.circle(-5,180)
turtle.seth(90)
turtle.circle(-5,180)
turtle.seth(90)
turtle.circle(-5,180)
turtle.seth(90)
turtle.circle(-5,180)
turtle.seth(90)
turtle.circle(-5,180)
turtle.seth(90)
turtle.circle(-5,180)
turtle.pu()
turtle.goto(-25,-85)
turtle.pd()
turtle.seth(90)
turtle.circle(-5,180)
turtle.seth(90)
turtle.circle(-5,180)
turtle.seth(90)
turtle.circle(-5,180)
turtle.seth(90)
turtle.circle(-5,180)
turtle.seth(90)
turtle.circle(-5,180)
turtle.pu()运行上述代码，我们可以看到老鼠身体的绘制过程，如下动图所示：
这里先不将其汇合在一起，待几个部件都完成之后，我们再将其组成一个完整地老鼠。
三、绘制手
上面绘制的身体还缺了两只手，对了，还有袍子上的一个大金钱，我们将其补上：
def hands():
turtle.goto(-8, -25)
turtle.pd()
turtle.seth(30)
turtle.forward(10)
turtle.seth(0)
turtle.circle(-10, 50)
turtle.seth(210)
turtle.forward(18)
turtle.back(10)
turtle.seth(-45)
turtle.forward(10)
turtle.back(10)
turtle.seth(30)
turtle.forward(8)
turtle.seth(300)
turtle.forward(5)
turtle.pu()
turtle.goto(0, -75)
turtle.pd()
turtle.seth(0)
turtle.circle(10)
turtle.seth(90)
turtle.circle(10, 90)
turtle.seth(0)
turtle.circle(10, 90)
turtle.seth(270)
turtle.circle(10, 90)
turtle.seth(180)
turtle.circle(10, 90)
turtle.pu()拱手和金钱没有和身体结合在一起时，暂时看不出上面效果来，如下动图所示：
四、绘制帽子
老鼠还戴了一顶金钱帽，咱们（zmister.com）现在给它加上：
def hat():
# 画帽子
turtle.goto(-20,98)
turtle.pd()
turtle.seth(80)
turtle.forward(20)
turtle.seth(60)
turtle.circle(-20,140)
turtle.seth(-85)
turtle.forward(18)
turtle.pu()
turtle.goto(-20,98)
turtle.pd()
turtle.seth(80)
turtle.forward(5)
turtle.seth(30)
turtle.forward(22)
turtle.seth(-25)
turtle.forward(24)
turtle.pu()
turtle.goto(0,127)
turtle.pd()
turtle.seth(0)
turtle.circle(5)
turtle.pu()
turtle.goto(0,125)
turtle.pd()
turtle.seth(270)
turtle.forward(10)
turtle.pu()
# 右边抖带
turtle.goto(19,110)
turtle.pd()
turtle.seth(30)
turtle.circle(40,50)
turtle.seth(0)
turtle.circle(10)
turtle.seth(90)
turtle.circle(10,90)
turtle.seth(0)
turtle.circle(10,90)
turtle.seth(270)
turtle.circle(10,90)
turtle.seth(180)
turtle.circle(10,90)
turtle.pu()
# 左边抖带
turtle.goto(-19,110)
turtle.pd()
turtle.seth(150)
turtle.circle(-40,50)
turtle.seth(0)
turtle.circle(10)
turtle.seth(90)
turtle.circle(10,90)
turtle.seth(0)
turtle.circle(10,90)
turtle.seth(270)
turtle.circle(10,90)
turtle.seth(180)
turtle.circle(10,90)
turtle.pu()帽子主要都是由圆构成，其绘制过程如下动图所示：
五、绘制尾巴
先不着急为老鼠带上金钱帽，我们还忘记了老鼠有一根长长的尾巴，为它补上吧：
def tail():
turtle.goto(30, -60)
turtle.pd()
turtle.seth(20)
turtle.circle(40, 80)
turtle.circle(-20, 180)
turtle.circle(-10, 90)尾巴就是两个方向相反弧度不同的圆，效果我们就不演示了。
最后将其结合在一起：
if __name__ == '__main__':
head()
body()
hands()
hat()
tail()
turtle.done()我们就可以看到一个完整的鼠年福鼠绘制过程，如下动图所示：
