python实现带声音的摩斯码翻译实现方法

本文实例讲述了python实现带声音的摩斯码翻译程序，分享给大家供大家参考。具体分析如下：

这里需要使用PyGame来发出声音。

import pygame
import time
import sys
CODE = {\'A\': \'.-\',   \'B\': \'-...\',  \'C\': \'-.-.\', 
    \'D\': \'-..\',  \'E\': \'.\',   \'F\': \'..-.\',
    \'G\': \'--.\',  \'H\': \'....\',  \'I\': \'..\',
    \'J\': \'.---\',  \'K\': \'-.-\',  \'L\': \'.-..\',
    \'M\': \'--\',   \'N\': \'-.\',   \'O\': \'---\',
    \'P\': \'.--.\',  \'Q\': \'--.-\',  \'R\': \'.-.\',
     \'S\': \'...\',  \'T\': \'-\',   \'U\': \'..-\',
    \'V\': \'...-\',  \'W\': \'.--\',  \'X\': \'-..-\',
    \'Y\': \'-.--\',  \'Z\': \'--..\',
    \'0\': \'-----\', \'1\': \'.----\', \'2\': \'..---\',
    \'3\': \'...--\', \'4\': \'....-\', \'5\': \'.....\',
    \'6\': \'-....\', \'7\': \'--...\', \'8\': \'---..\',
    \'9\': \'----.\' 
    }
ONE_UNIT = 0.5
THREE_UNITS = 3 * ONE_UNIT
SEVEN_UNITS = 7 * ONE_UNIT
PATH = \'morse_sound_files/\'
def verify(string):
  keys = CODE.keys()
  for char in string:
    if char.upper() not in keys and char != \' \':
      sys.exit(\'Error the charcter \' + char + \' cannot be translated to Morse Code\')
def main():
  print \'Welcome to Alphabet to Morse Code Translator v.01\\n\'
  msg = raw_input(\'Enter Message: \')
  verify(msg)
  print
  pygame.init()
  for char in msg:
    if char == \' \':
      print \' \'*7,
      time.sleep(SEVEN_UNITS)
    else:
      print CODE[char.upper()],
      pygame.mixer.music.load(PATH + char.upper() + \'_morse_code.ogg\')
      pygame.mixer.music.play()
      time.sleep(THREE_UNITS)
if __name__ == \"__main__\":
  main()
