该博客演示了如何用Python的turtle模块来绘制七段数码管，并结合当前日期进行显示。通过定义drawDigit函数来绘制数字，drawDate函数将日期转换为七段数码管形式，并使用不同颜色区分年、月、日。

import turtle
import time

def drawGap():
turtle.penup()
turtle.fd(5)

def drawLine(draw):
drawGap()
turtle.pendown() if draw else turtle.penup()
turtle.fd(40)
drawGap()
turtle.right(90)

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 [0,1,2,3,4,8,9] else drawLine(False)
turtle.left(180)
turtle.penup()
turtle.fd(20)

def drawDate(date):
turtle.pencolor("red")
for i in date:
if i == '-':
turtle.write('年',font=('Arial',20,'normal'))
turtle.pencolor('green')
turtle.fd(40)
elif i == '=':
turtle.write('月',font=('Arial',20,'normal'))
turtle.pencolor('blue')
turtle.fd(40)
elif i == '+':
turtle.write('日',font=('Arial',20,'normal'))
else:
drawDigit(eval(i))
def main():
turtle.setup(1000,450,200,200)
turtle.penup()
turtle.fd(-300)
turtle.pensize(5)
drawDate(time.strftime("%Y-%m=%d+",time.gmtime()))
turtle.hideturtle()
turtle.done()
main()
