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：

总结

以上所述是小编给大家介绍的通过Turtle库在Python中绘制一个鼠年福鼠，希望对大家有帮助！
