今年这个鼠年，尽管只是刚过了一个开头，但现实仿佛把我们很多年才需要经历的不好的事情，都在一瞬间抛向了我们，这个鼠年好像缺了点福气，本节我们使用 Python 画一只福鼠，为大家增添点福气，我们需要用到的是 turtle 库。

头部

首先，我们画福鼠的头部，头部主要包括：眼睛、耳朵、鼻子、胡子、牙齿等，代码实现如下所示：

import turtle    def head():      turtle.color('black')      # 脸轮廓      turtle.fillcolor('#FFE4B5')      turtle.begin_fill()      # 落笔      turtle.pd()      # 画一个半径为指定值的圆      turtle.circle(50)      # 提笔      turtle.pu()      turtle.end_fill()      # 移动到指定坐标位置，参数 1 代表 x 轴位置，参数 2 代表 y 轴位置      turtle.goto(50, 60)      turtle.pd()      turtle.circle(25, 255)      turtle.pu()      turtle.goto(60, 80)      turtle.pd()      turtle.circle(-10, -200)      turtle.pu()      turtle.goto(-50, 60)      turtle.pd()      # 按逆时针改变行进方向      turtle.seth(180)      turtle.circle(-25, 255)      turtle.pu()      turtle.goto(-60, 80)      turtle.pd()      turtle.circle(10, -200)      turtle.pu()      # 眼睛      turtle.goto(10, 65)      turtle.seth(45)      turtle.pd()      turtle.circle(-8, 360)      turtle.pu()      turtle.goto(13, 62)      turtle.fillcolor('black')      turtle.begin_fill()      turtle.pd()      turtle.circle(-4, -360)      turtle.pu()      turtle.end_fill()      turtle.goto(-10, 65)      turtle.seth(135)      turtle.pd()      turtle.circle(8, 360)      turtle.pu()      turtle.goto(-13, 62)      turtle.fillcolor('black')      turtle.begin_fill()      turtle.pd()      turtle.circle(4, 360)      turtle.pu()      turtle.end_fill()      # 鼻子      turtle.goto(-6, 45)      turtle.seth(70)      turtle.fillcolor('red')      turtle.begin_fill()      turtle.pd()      turtle.circle(-6, 150)      turtle.pu()      turtle.end_fill()      turtle.goto(-6, 45)      turtle.seth(-70)      turtle.fillcolor('red')      turtle.begin_fill()      turtle.pd()      turtle.circle(6, 150)      turtle.pu()      turtle.end_fill()      # 嘴      turtle.goto(0, 40)      turtle.seth(270)      turtle.pd()      turtle.forward(7)      turtle.pu()      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()      # 牙齿      turtle.goto(0, 33)      turtle.seth(270)      turtle.pd()      turtle.forward(13)      turtle.seth(180)      turtle.forward(6)      turtle.seth(90)      turtle.forward(13)      turtle.pu()      turtle.goto(6, 33)      turtle.seth(270)      turtle.pd()      turtle.forward(13)      turtle.seth(180)      turtle.forward(6)      turtle.pu()      # 胡子      turtle.goto(30, 30)      turtle.seth(8)      turtle.pd()      turtle.circle(-40, 40)      turtle.pu()      turtle.goto(30, 25)      turtle.seth(-5)      turtle.pd()      turtle.circle(-40, 40)      turtle.pu()      turtle.goto(30, 20)      turtle.seth(-18)      turtle.pd()      turtle.circle(-40, 40)      turtle.pu()      turtle.goto(-30, 30)      turtle.seth(172)      turtle.pd()      turtle.circle(40, 40)      turtle.pu()      turtle.goto(-30, 25)      turtle.seth(188)      turtle.pd()      turtle.circle(40, 40)      turtle.pu()      turtle.goto(-30, 20)      turtle.seth(196)      turtle.pd()      turtle.circle(40, 40)      turtle.pu()

帽子

接下来给福鼠画一顶帽子，我们打算把这顶帽子画得古风一点，原型选了电视剧中宋朝官员的官帽，代码实现如下所示：

def hat():      turtle.goto(-20, 97)      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(50, 115)      turtle.pd()      turtle.goto(-50, 115)      turtle.pu()      turtle.end_fill()      turtle.goto(19, 115)      turtle.pd()      turtle.goto(50, 115)      turtle.seth(0)      turtle.fillcolor('gold2')      turtle.begin_fill()      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()      turtle.end_fill()      turtle.goto(-19, 115)      turtle.pd()      turtle.goto(-50, 115)      turtle.seth(0)      turtle.fillcolor('gold2')      turtle.begin_fill()      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()      turtle.end_fill()

身体

我们知道福鼠本身并不是真实存在的，而是一种以动物为原型的虚拟化形象，这种形象一般都是头部保留了动物本身的面貌，而身体是人类身体的形状，比如：西游记中孙悟空、猪八戒就是这样的，这里我们也把福鼠的身体画成人身体的形状，代码实现如下所示：

def body():      # 上半身      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.circle(10, 100)      turtle.seth(180)      turtle.forward(10)      turtle.pu()      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.circle(-10, 100)      turtle.seth(0)      turtle.forward(10)      turtle.pu()      turtle.goto(-20, 4)      turtle.pd()      turtle.goto(-16, -4)      turtle.goto(16, -4)      turtle.goto(20, 4)      turtle.pu()      turtle.goto(0, -5)      turtle.pd()      turtle.goto(0, -50)      turtle.pu()      turtle.goto(-30, -48)      turtle.pd()      turtle.goto(-30, -60)      turtle.pu()      turtle.goto(30, -48)      turtle.pd()      turtle.goto(30, -60)      turtle.pu()      turtle.goto(-30, -55)      turtle.pd()      turtle.goto(30, -55)      turtle.pu()      turtle.goto(-30, -60)      turtle.pd()      # 参数 1 为绘制颜色，参数 2 为填充颜色      turtle.color('black', 'red')      turtle.begin_fill()      turtle.goto(30, -60)      turtle.pu()      # 下半身      turtle.goto(-25, -60)      turtle.pd()      turtle.goto(-35, -100)      turtle.goto(-20, -100)      turtle.goto(-0, -60)      turtle.goto(20, -100)      turtle.goto(35, -100)      turtle.goto(25, -60)      turtle.end_fill()      turtle.pu()      turtle.goto(-33, -100)      turtle.pd()      turtle.color('black', 'blue')      turtle.begin_fill()      turtle.seth(270)      turtle.circle(6, 180)      turtle.end_fill()      turtle.pu()      turtle.goto(33, -100)      turtle.pd()      turtle.color('black', 'blue')      turtle.begin_fill()      turtle.seth(270)      turtle.circle(-6, 180)      turtle.end_fill()      turtle.pu()

文字

福鼠当然少不了祝福语，我找了四句：鼠你有钱、鼠你健康、鼠你快乐、鼠你幸运，最后，我们把这四个词语分别画在福鼠的四周，代码实现如下所示：

def word():      turtle.color('red')      turtle.goto(-30, 150)      turtle.pd()      turtle.write('鼠', move=False, align='center', font=('Arial', 14, 'normal'))      turtle.pu()      turtle.goto(-10, 150)      turtle.pd()      turtle.write('你', move=False, align='center', font=('Arial', 14, 'normal'))      turtle.pu()      turtle.goto(10, 150)      turtle.pd()      turtle.write('有', move=False, align='center', font=('Arial', 14, 'normal'))      turtle.pu()      turtle.goto(30, 150)      turtle.pd()      turtle.write('钱', move=False, align='center', font=('Arial', 14, 'normal'))      turtle.pu()      turtle.goto(-30, -150)      turtle.pd()      turtle.write('鼠', move=False, align='center', font=('Arial', 14, 'normal'))      turtle.pu()      turtle.goto(-10, -150)      turtle.pd()      turtle.write('你', move=False, align='center', font=('Arial', 14, 'normal'))      turtle.pu()      turtle.goto(10, -150)      turtle.pd()      turtle.write('健', move=False, align='center', font=('Arial', 14, 'normal'))      turtle.pu()      turtle.goto(30, -150)      turtle.pd()      turtle.write('康', move=False, align='center', font=('Arial', 14, 'normal'))      turtle.pu()      turtle.goto(-90,-10)      turtle.pd()      turtle.write('鼠', move=False, align='center', font=('Arial', 14, 'normal'))      turtle.pu()      turtle.goto(-90, -30)      turtle.pd()      turtle.write('你', move=False, align='center', font=('Arial', 14, 'normal'))      turtle.pu()      turtle.goto(-90, -50)      turtle.pd()      turtle.write('快', move=False, align='center', font=('Arial', 14, 'normal'))      turtle.pu()      turtle.goto(-90, -70)      turtle.pd()      turtle.write('乐', move=False, align='center', font=('Arial', 14, 'normal'))      turtle.pu()      turtle.goto(90, -10)      turtle.pd()      turtle.write('鼠', move=False, align='center', font=('Arial', 14, 'normal'))      turtle.pu()      turtle.goto(90, -30)      turtle.pd()      turtle.write('你', move=False, align='center', font=('Arial', 14, 'normal'))      turtle.pu()      turtle.goto(90, -50)      turtle.pd()      turtle.write('幸', move=False, align='center', font=('Arial', 14, 'normal'))      turtle.pu()      turtle.goto(90, -70)      turtle.pd()      turtle.write('运', move=False, align='center', font=('Arial', 14, 'normal'))      turtle.pu()      turtle.hideturtle()

调用代码如下：

if __name__ == '__main__':      head()      hat()      body()      word()      # 隐藏画笔      turtle.hideturtle()      # 停止画笔，但不关闭窗体      turtle.done()

总结

本文我们使用 Python 的 turtle 库画了一只福鼠，不知道与大家想象中的福鼠形象一样吗？如果不一样呢，大家可以自己动手把这只福鼠修改成自己理想中的样子。
