Python 批量下载单词音频程序

前一段时间背TOEFL单词时为了能批量下载单词的音频，用Python实现了个小脚本(真的好方便啊^^)

读取words.txt文件，文件内部格式需要是一个单词一行，可以有空行。多个单词也可以，不过那样子是一个音频文件包含多个单词了

然后生成audio文件夹，文件命名为 “序号_单词”的形式。

#coding=utf-8
#Reading words from words.txt which contains single word in every line and downloading audio of those words from http://dict.youdao.com/dictvoice

import urllib
import urllib2
import os

headers = {"User-Agent":"Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)"}

url = "http://dict.youdao.com/dictvoice"

f = open("words.txt", "r")
count = 1
os.mkdir("audio")
os.chdir('audio')
while True:
    line = f.readline()
    if line:
        if line=='\n': #ignore empty line
            continue
        word = line  #the word you gonna find
        country = "2" #1 means British English，2 means Ameican English
        params = {"audio":word, "type":country}
        data = urllib.urlencode(params)

        request = urllib2.Request(url, data, headers)
        response = urllib2.urlopen(request)
        
        fs = open("%d_%s.mp3"%(count,word.strip()), 'wb') #using counting number and word as file's name
        fs.write(response.read())  #response.read() means return audio 
        fs.close()
        count = count + 1
    else:
        break

f.close()
