前言：
這篇文章給大家介紹了怎樣用python創建一個簡單的報警，它可以運行在命令行終端，它需要分鐘做為命令行參數，在這個分鐘后會打印”wake-up”消息，并響鈴報警，你可以用0分鐘來測試，它會立即執行，用揚聲器控制面板調整聲音。
以下是腳本：

# 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 sysimport stringfrom time import sleep sa = sys.argvlsa = 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 |
總結：
這個腳本我工作中已經在使用了，非常實用，當然為避免影響其他同事工作，你最好帶耳機，如果要求不高，其實從終端打印出的”wake-up”消息已經足夠提醒的了。以上就是這篇文章的全部內容，希望對大家的學習和工作能帶來一定的幫助，如果有疑問大家可以留言交流。謝謝大家對服務器之家的支持。
