本文将用Python调用谷歌翻译API实现文本翻译；

使用Python向谷歌翻译URL进行GET请求，得到网页内容后使用正则表达式进行解析，获得翻译结果；

import re
import html
from urllib import parse
import requestsGOOGLE_TRANSLATE_URL = 'http://translate.google.com/m?q=%s&tl=%s&sl=%s'def translate(text, to_language="auto", text_language="auto"):text = parse.quote(text)url = GOOGLE_TRANSLATE_URL % (text,to_language,text_language)response = requests.get(url)data = response.textexpr = r'(?s)class="(?:t0|result-container)">(.*?)<'result = re.findall(expr, data)if (len(result) == 0):return ""return html.unescape(result[0])print(translate("你是谁？", "en","zh-CN")) #汉语转英语
print(translate("你是谁？", "ja","zh-CN")) #汉语转日语
print(translate("who are you?", "zh-CN","en")) #英语转汉语
