想了解用Python实现命令行闹钟脚本实例的相关内容吗,在本文为您仔细讲解Python实现命令行闹钟脚本的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:python,命令行,python,闹钟,运行python脚本,下面大家一起来学习吧。

前言:

这篇文章给大家介绍了怎样用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.

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

总结:

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。以上就是这篇文章的全部内容,希望对大家的学习和工作能带来一定的帮助,如果有疑问大家可以留言交流。谢谢大家对的支持。
