Python實作命令列鬧鐘腳本

前言：

這篇文章給大家介紹了怎樣用python創建一個簡單的警報，它可以運行在命令行終端，它需要分鐘做為命令行參數，在這個分鐘後會列印」wake-up」訊息，並響鈴警報，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.

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

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」訊息已經夠提醒的了。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PHP中文網的支持。
