python繪制七段數碼管

七段數碼管可以用來表示我們生活中的數字，繪制過程主要有turtle和函數實現，下面是七段數碼管的原理

 

 代碼如下：

import turtle
import time
#繪制一條線，並且將turtle轉向
def drawLine(draw):
    # 使每一條線段起末存在間隙
    drawGap()
    turtle.pendown() if draw else turtle.penup()
    turtle.fd(40)
    # 使每一條線段起末存在間隙
    drawGap()
    turtle.right(90)
#使每一條線段起末存在間隙
def drawGap():
    turtle.penup()
    turtle.fd(5)
#繪制一個數
def drawDigit(digit):
    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):
    for i in date:
        if i=='N':
            turtle.pencolor("green")
            turtle.write('年',font=("Arial",18,"normal"))
            turtle.fd(40)
        elif i=='Y':
            turtle.pencolor("green")
            turtle.write('月',font=("Arial",18,"normal"))
            turtle.fd(40)
        elif i=='R':
            turtle.pencolor("green")
            turtle.write('日',font=("Arial",18,"normal"))
            turtle.fd(40)
        else:
            turtle.pencolor("purple")
            drawDigit(eval(i))
def main():
    turtle.setup(800,350,200,200)
    turtle.penup()
    turtle.fd(-300)
    turtle.pensize(5)
    #獲取當前時間並且對時間格式進行標准化
    drawDate(time.strftime('%YN%mY%dR',time.gmtime()))
    turtle.hideturtle()
    turtle.done()

main()

運行結果如下：
