在python中检测（哪个用户被登录）和（关闭/注销）

Question

我写了一个程序（感谢Windows after starting文件夹）在登录后启动，将当前时间写入日志，然后根据输入的名称（字符串）将信息放入日志。你知道吗

这是公平划分时间，我和我的兄弟可以在电脑上（这里不重要），我想让他不可吃（日志是当前的安全）。你知道吗

如果您选择（通过input()），它将关闭或注销您的计算机后，它将结束时间写入日志。你知道吗

同时，它会将当前状态（谁有时间，有多少时间）写入cas.txt（用英语读time.txt）。这是很容易被他和我，你有时我不得不重写它的基础上的日志，因为他“作弊”。你知道吗

日志文件称为zaznam.txt。你知道吗

我想用两种方式升级它：

• 我想检测哪个用户已登录（因此不需要更多的名称输入=>；我们的名称将在日志中没有例外）
• 当按下Windows logg out或turn off按钮时，我想启动一个程序，将最后一个pice添加到日志中（这样他就不能删除跳过名称编写然后计算时间的程序）（如果在python中可能的话）或
• 当程序退出时（按cross/Alt+F4），它将记录用户的日志（如果可能的话）

我的操作系统是Windows7

文件看起来是什么样的（你其实不需要读这个，只是表明我做了一些工作，没有什么可以帮助你回答）：

cas.txt（实际时间统计，易于访问）

Tonda 0:00:00
Janek 4 days, 12:01:20

意思是：

my name, my spend time
his name, his spend time

zaznam.txt=log中的一行（他可能不知道或不理解它）注意：它被制表符分隔，所以在这里不太容易看到：/。你知道吗

2015-10-22 11:58:38.024605  Tonda 0:00:00;Janek 3 days, 2:19:31 Janek           2015-10-22 12:37:59.020734  Tonda 0:00:00;Janek 3 days, 2:58:51
>>>>>>>time started<<<<<<<  >>>>>what "cas.txt" looked like<<<< >inputed name<  >>>>>>>>time ended<<<<<<<<  >>>what "cas.txt" now looks like<<<

还有一个计划（我不认为这对不说捷克语的人来说很清楚）：

import datetime
import time

a = datetime.datetime.today()

###
zaznam = open("zaznam.txt", 'a')

zaznam.write("\n")

zaznam.write(str(a))

oldcas = open("cas.txt", "r").read().replace("\n", ";")
print(oldcas)
zaznam.write("\t" + oldcas)
zaznam.close()
###

jmeno = None
while (jmeno != "Tonda") and (jmeno != "Janek"):
    jmeno = input("Zadej jméno (Janek/Tonda):\n")

###
zaznam = open("zaznam.txt", 'a')
zaznam.write("\t" + jmeno)
zaznam.close()
###

turnoff = input("Zmáčkni enter pro ukončení a něco před tím napiš, pokud chceš vypnout PC")

b = datetime.datetime.today()

###
zaznam = open("zaznam.txt", 'a')
zaznam.write("\t" + str(b))
zaznam.close()
