利用python函数绘制七段数码管

import turtle,time def drawgap(): #绘制数码管间隔 turtle.penup() turtle.fd(5) def drawline(draw): #绘制单段数码管 drawgap() turtle.pendown() if draw else turtle.penup() turtle.fd(40) drawgap() turtle.right(90) def drawdigit(digit): #根据数字绘制七段数码管 drawline(True) if digit in [2, 3, 4, 5, 6, 8, 9] else drawline(False) drawline(True) if digit in [0, 1, 3, 4, 5, 6, 7, 8, 9] else drawline(False) drawline(True) if digit in [0, 2, 3, 5, 6, 8, 9] else drawline(False) drawline(True) if digit in [0, 2, 6, 8] else drawline(False) turtle.left(90) drawline(True) if digit in [0, 4, 5, 6, 8, 9] else drawline(False) drawline(True) if digit in [0, 2, 3, 5, 6, 7, 8, 9] else drawline(False) drawline(True) if digit in [0, 1, 2, 3, 4, 7, 8, 9] else drawline(False) turtle.left(180) turtle.penup() turtle.fd(20) def drawdate(date): #date为日期,格式为‘%Y-%X=%d+' turtle.pencolor("red") for i in date: if i == '-': turtle.write('年',font=("Arial",18,"normal")) turtle.pencolor("green") turtle.fd(40) elif i == '=': turtle.write('月', font=("Arial", 18, "normal")) turtle.pencolor("blue") turtle.fd(40) elif i == '+': turtle.write('日', font=("Arial", 18, "normal")) else: drawdigit(eval(i)) def main(): turtle.setup(800, 350, 200, 200) turtle.penup() turtle.fd(-300) turtle.pensize(5) drawdate(time.strftime('%Y-%m=%d+',time.gmtime()))#获取系统时间并进行格式化 turtle.hideturtle() turtle.done() main()

运行结果： 总结：

模块化思维：确定模块接口，封装功能规则化思维：抽象过程为规则，计算机自动执行化繁为简：将大功能变为小功能组合，分而治之

举一反三：
