我修改了一个python babelizer来帮助我将英语翻译成中文。

Summary:
import babelizer
print ' '.join(babelizer.available_languages)
print babelizer.translate( 'How much is that doggie in the window?',
'English', 'French' )
def babel_callback(phrase):
print phrase
sys.stdout.flush()
babelizer.babelize( 'I love a reigning knight.',
'English', 'German',
callback = babel_callback )
available_languages
A list of languages available for use with babelfish.
translate( phrase, from_lang, to_lang )
Uses babelfish to translate phrase from from_lang to to_lang.
babelize(phrase, from_lang, through_lang, limit = 12, callback = None)
Uses babelfish to translate back and forth between from_lang and
through_lang until either no more changes occur in translation or
limit iterations have been reached, whichever comes first. Takes
an optional callback function which should receive a single
parameter, being the next translation. Without the callback
returns a list of successive translations.
It's only guaranteed to work if 'english' is one of the two languages
given to either of the translation methods.
Both translation methods throw exceptions which are all subclasses of
BabelizerError. They include
LanguageNotAvailableError
Thrown on an attempt to use an unknown language.
BabelfishChangedError
Thrown when babelfish.altavista.com changes some detail of their
layout, and babelizer can no longer parse the results or submit
the correct form (a not infrequent occurance).
BabelizerIOError
Thrown for various networking and IO errors.

Various patterns I have encountered in looking for the babelfish result.
We try each of them in turn, based on the relative number of times I've
seen each of these patterns. $1.00 to anyone who can provide a heuristic
for knowing which one to use. This includes AltaVista employees.

，测试代码是
import babelizer
print ' '.join(babelizer.available_languages)
result = babelizer.translate( 'How much is that dog in the window?', 'English', 'chinese' )
f = open('result.txt', 'wb')
f.write(result)
f.close()
print result
结果是在div块内预期的。我修改了脚本以保存html响应。我发现所有utf8字符都转为nul。我是否需要特别注意治疗utf8反应？
答案 0 :(得分：1)
我认为你需要使用
import codecs
codecs.open
而不是明白
saveHTML
方法，处理utf-8文档。有关完整说明，请参阅Python Unicode Howto。
希望这有帮助。
