用Python实现命令行闹钟脚本实例
作者:daisy 时间:2023-01-19 12:57:09
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.
# 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
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。谢谢大家对脚本之家的支持。
