Python实现七段数码管时钟(动态刷新版)

Posted 2022-04-03 振华OPPO

利用turtle库、datetime库和time库，获取并描绘出现在的系统时间，并且时间具有动态刷新功能，即每秒刷新一次。

实现代码如下：

from turtle import *
from datetime import datetime
import time
def drawGap():
    penup()
    fd(5)
def drawLine(draw):
    drawGap()
    pendown() if draw else penup()
    fd(40)
    drawGap()
    right(90)
def drawDigit(d):
    speed(50)
    drawLine(True) if d in [2,3,4,5,6,8,9] else drawLine(False)
    drawLine(True) if d in [0,1,3,4,5,6,7,8,9] else drawLine(False)
    drawLine(True) if d in [0,2,3,5,6,8,9] else drawLine(False)
    drawLine(True) if d in [0,2,6,8] else drawLine(False)
    left(90)
    drawLine(True) if d in [0,4,5,6,8,9] else drawLine(False)
    drawLine(True) if d in [0,2,3,5,6,7,8,9] else drawLine(False)
    drawLine(True) if d in [0,1,2,3,4,7,8,9] else drawLine(False)
    left(180)
    penup()
    fd(20)
def drawDate(date):
    pencolor(Red)
    for i in date:
        if i=="-":
            write(时,font=(Arial,24,normal))
            pencolor(Green)
            fd(40)
        elif i===:
            write(分, font=(Arial, 24, normal))
            pencolor(Blue)
            fd(40)
        elif i==+:
            write(秒, font=(Arial, 24, normal))
        else:
            drawDigit(eval(i))
def main():
    setup(800,350,200,200)
    while True:
        reset()
        penup()
        fd(-300)
        pensize(8)
        tracer(False)
        hideturtle()
        drawDate(datetime.now().strftime(%H-%M=%S+))
        time.sleep(1)
    done()
main()

运行效果如图：
