摘要:前言:這篇文章給大家介紹了怎樣用python創(chuàng)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(shù),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(zhí)行,用揚聲器控制面板調(diào)整聲音。以下是腳本:# alarm_clock.py # Description: A simple

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 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
