[python]计算机使用过程中，眼睛强制休息

前言

现在的电脑族们，在使用电脑的过程中，常常忘记了时间的流逝，要么忙碌在电视剧的观看中，要么忙碌在工作中，要么忙碌在游戏中，往往忽视了对眼睛的正常保护，让眼睛能够在空闲的时候获得足够的休息时间。

我也是其中之一。

但当我发现自己的眼睛的疲劳程度在慢慢增加的时候，对于视力保护的需求也越来越迫切了。

于是，利用自己的小小编程技巧，利用python的简易性，实现了下面的“强制眼睛休息的脚本”，当设定的工作时间结束后，计算机的显示器会被强制关闭，如果用鼠标进行强制唤醒，显示器依然会随后快速关闭，直到设定的休息时间都过去以后，显示器才会开启。

具体实现如下

"""
count down the time to close the display

"""
import time
import os
import platform

work_time = int(raw_input("Enter your work time [min]: "))
break_time = int(raw_input("Enter your break time [min]: "))
break_time = break_time*60
start = raw_input("Do you want start [y/n]: ")
os_str = platform.system()

work_stage = 0
while (start == 'y'):
    for i in range(work_time):
        print  'Remain ', work_time-i, 'min'
        time.sleep(60)

    # During the break time
    # the display should always be closed
    # if rewake by mouse, it will be closed again
    insleep = 1
    start_time = time.time()
    while (insleep):
        if os_str == "Windows":
            # Under windows, nircmd should be installed first
            # The usage can reference: www.nirsoft.net/utils/nircmd.html
            os.system("nircmd.exe monitor off")
        elif os_str == "Linux":
            os.system("xset dpms force off")
        end_time = time.time()
        if end_time-start_time > break_time:
            insleep = 0

    if os_str == "Linux":
        os.system("xset dpms force on")
    elif os_str == "Windows":
        os.system("nircmd.exe monitor on")

    work_stage = work_stage + 1
    print "================
Work Stage ", work_stage,"
================
"
    start = raw_input("Do you want continue [y/n]: ")
