python使用百度api翻譯中英文

寫程序取變量名的時(shí)候,常常需要翻譯單詞,或者將中文翻譯成英語(yǔ).有道詞典,必應(yīng)詞典都很好,可是...命令行習(xí)慣了還是覺(jué)得用在cmd里面調(diào)出程序使用起來(lái)也許會(huì)更爽.于是查了查python相關(guān)的翻譯腳本.都很簡(jiǎn)單,獲取網(wǎng)頁(yè),然后解析,沒(méi)找到用requeset庫(kù)的.于是自己用request庫(kù)寫了個(gè).. 雖然簡(jiǎn)單,但是實(shí)用就好啦~~ 上網(wǎng)搜索發(fā)下百度的翻譯api有demo
稍微修改一下就可以直接使用了

'''

appid = '20151113000005349'

    m1 = md5.new()
    m1.update(sign)
    sign = m1.hexdigest()

    httpClient = httplib.HTTPConnection('api.fanyi.baidu.com')
    myurl = '/api/trans/vip/translate'
    myurl = myurl+'?appid='+appid+'&q='+urllib.quote(word)+'&from='+fromLang+'&to='+toLang+'&salt='+str(salt)+'&sign='+sign
    httpClient.request('GET', myurl)
    #response是HTTPResponse對(duì)象
    response = httpClient.getresponse()
    result = response.read()
    ret = json.loads(result)
    print(ret["trans_result"][0]["dst"])
    httpClient.close()


#判斷首字母是否是英文字母從而判斷是英譯漢or漢譯英
def is_english_char(ch):
    if ord(ch) not in range(97,122) and ord(ch) not in range(65,90):
        return False
    return True


if __name__ == '__main__':
    import sys
    word = (len(sys.argv) > 1) and sys.argv[1] or None
    queryOnce = (word != None)

    while True:
        try:
            if word == None:
                word = raw_input("
  input word to translate ,#[ input "!"exit ]
>")

            if word == "!":
                break

            fromLang = "en"
            toLang = "zh"
            if not is_english_char(word[0]):
                fromLang = "zh"
                toLang = "en"
                word = word.decode('gbk').encode('utf-8')

            requestTranslate(word,fromLang,toLang)
            word = None

            if queryOnce == True:
                break
        except Exception,e:
            print('!!!!! catch error!! ' + str(e))
            word = None

推薦將如下 腳本放在 環(huán)境變量里邊,直接 win+r , tw english 或者 tw 中文~~
效果更快

@echo off
set OLD_DIR=%cd%
set DIR=%~dp0
cd /d %DIR%

python .	ranslate_word_new.py %1

pause
