Python 入门学习（壹）上机时间提醒

• 基于 Udacity 的 Python 入门课程 Programming Foundations with Python
• 基于 Python 2.7

控制台版本

思路

Project 1 是一个时间提醒助手，从打开程序开始计时，每两个小时打开一个 Youtube 上的视频链接。我想也许能够做一个更完善的版本——以开机时间为原点，计算上机的时长，每两个小时弹出一个 MessageBox 提示休息。

代码

import time
import os
from datetime import datetime
import psutil
import sys
from time import sleep
import Tkinter as tk
import tkMessageBox

count = 0
while 1:
os.system('cls') #清屏实现动态显示
bTime = datetime.fromtimestamp(psutil.boot_time()) #获取开机时间
print "Boot Time:", #不换行输出
print bTime
cTime = datetime.now() #获取当前时间
print "Current Time:",
print cTime
dTime = (cTime - bTime) #计算用机时长
print "Running Seconds:",
print dTime.seconds,
print "s"
time = int(dTime.seconds)
if (time/7200 > count):
tkMessageBox.showinfo(title = 'Notice', message = 'You Should Have a Rest') #弹出提示框
count+=1
sleep(1)

if __name__=="__main__":
main()

效果

GUI 版本

思路

既然都用上了 Tkinter，何不直接来一个 GUI 界面呢。不过如果是 Tkinter 的话，代码就需要完全重构了。

代码

#coding=utf-8
import os
from datetime import datetime
import psutil
import sys
from time import sleep
from Tkinter import *
import tkMessageBox
import time

def tick():
global time1
# 获取当前系统时间
time2 = time.strftime('%H:%M:%S')
# 动态显示
if time2 != time1:
time1 = time2
clock.config(text=time2)
clock.after(200, tick)

def timer():
global dTime1
bTime = datetime.fromtimestamp(psutil.boot_time())
cTime = datetime.now()
dTime2 = (cTime - bTime).seconds
if dTime2 != dTime1:
dTime1 = dTime2
runn.config(text=str(dTime2)+' s')
runn.after(800, timer)

def msg():
global count
if (dTime1/7200 > count):
tkMessageBox.showinfo(title = 'Notice', message = 'You Should Have a Rest Now')
count+=1
tips.config(text="累计提示次数："+str(count))
tips.after(800, msg)

root = Tk()

#标题栏
root.title('Tik')
#窗体尺寸
#root.geometry('200x100')

#时钟
nclock = Label(root, text="当前时间", font=('DengXian', 15, 'bold'), relief=GROOVE)
nclock.grid(row=0, column=0)
time1 = ''
clock = Label(root, font=('DengXian', 15, 'bold'))
clock.grid(row=0, column=1)
tick()

#开机时间
nboot = Label(root, text="开机时间", font=('DengXian', 15, 'bold'), relief=GROOVE)
nboot.grid(row=1, column=0)
boottime = datetime.fromtimestamp(psutil.boot_time())
boottime = boottime.strftime('%H:%M:%S')
boot = Label(root, text=boottime, font=('DengXian', 15, 'bold'))
boot.grid(row=1, column=1)

#运行时长
nrun = Label(root, text="运行时长", font=('DengXian', 15, 'bold'), relief=GROOVE)
nrun.grid(row=2, column=0)
dTime1 = ''
runn = Label(root, font=('DengXian', 15, 'bold'))
runn.grid(row=2, column=1)
timer()

#运行状态
status = Label(root, text=" [ Running ] ", fg = 'green', bg = 'black', font=('DengXian', 10, 'bold'))
status.grid(row=10, column=0)
count = 0
tips = Label(root, fg = 'green', bg = 'black', font=('DengXian', 10, 'bold'))
tips.grid(row=10, column=1)
msg()

root.mainloop()
