超实用的报警脚本，这个脚本根据你设定的时间，到时会进行滴滴报警，主要应用场景是假设你在N分钟后有重要的事情要做（如妹子让你10分钟回电话），而你现在还命令行模式下（处理故障），你希望用最简单的方式到时能有提醒，那这个脚本就是为你准备的，本文原文是英文，我翻译了一小部分，文章末我给出了原文地址，以下是正文内容。
这个例子展示了怎样用python创建一个简单的报警，它可以运行在命令行终端，它需要分钟做为命令行参数，在这个分钟后会打印”wake-up”消息，并响铃报警，你可以用0分钟来测试，它会立即执行，用扬声器控制面板调整声音。
以下是脚本：

# alarm_clock.py # Description: A simple Python program to make the computer act # like an alarm clock. Start it running from the command line # with a command line argument specifying the duration in minutes # after which to sound the alarm. It will sleep for that long, # and then beep a few times. Use a duration of 0 to test the # alarm immediiately, e.g. for checking that the volume is okay. # Author: Vasudev Ram - http://www.dancingbison.com import sys import string from time import sleep sa = sys.argv lsa = len(sys.argv) if lsa != 2: print "Usage: [ python ] alarm_clock.py duration_in_minutes" print "Example: [ python ] alarm_clock.py 10" print "Use a value of 0 minutes for testing the alarm immediately." print "Beeps a few times after the duration is over." print "Press Ctrl-C to terminate the alarm clock early." sys.exit(1) try: minutes = int(sa[1]) except ValueError: print "Invalid numeric value (%s) for minutes" % sa[1] print "Should be an integer >= 0" sys.exit(1) if minutes < 0: print "Invalid value for minutes, should be >= 0" sys.exit(1) seconds = minutes * 60 if minutes == 1: unit_word = " minute" else: unit_word = " minutes" try: if minutes > 0: print "Sleeping for " + str(minutes) + unit_word sleep(seconds) print "Wake up" for i in range(5): print chr(7), sleep(1) except KeyboardInterrupt: print "Interrupted by user" sys.exit(1) # EOF |
这个脚本我工作中已经在使用了，非常实用，当然为避免影响其他同事工作，你最好带耳机，如果要求不高，其实从终端打印出的”wake-up”消息已经足够提醒的了。
