1、翻译模块、api使用分析

1、translate库：使用简单，但是有次数限制，翻译的准确性中等；
2、百度api（推荐使用）： 代码简单，有模块，但是需要注册，获取key值，翻译的准确性中下；
3、chrome翻译api：代码复杂，次数限制， 但是翻译的准确性较高；
4、有道翻译：代码复杂，次数限制，准确性中等；

2、使用方式：

1. translate库：

from translate import Translator
#在任何两种语言之间，中文翻译成英文
translator=Translator(from_lang="chinese",to_lang="english")
translation = translator.translate("床前明月光，疑是地上霜;举头望明月,低头思故乡")
print(translation)

2、 百度api：
需要先去百度翻译进行注册，获取appid、secretkey值，记得填写可访问的服务器ip

# 百度通用翻译API,不包含词典、tts语音合成等资源，如有相关需求请联系translate_api@baidu.com
# coding=utf-8import http.client
import hashlib
import urllib
import random
import jsondef trans_lang(q):trans_result = q# 百度appid和密钥需要通过注册百度【翻译开放平台】账号后获得appid = 'xxx'  # 填写你的appidsecretKey = 'xxx'  # 填写你的密钥httpClient = Nonemyurl = '/api/trans/vip/translate'  # 通用翻译API HTTP地址fromLang = 'en'  # 原文语种toLang = 'zh'  # 译文语种salt = random.randint(32768, 65536)# 手动录入翻译内容，q存放sign = appid + q + str(salt) + secretKeysign = hashlib.md5(sign.encode()).hexdigest()myurl = myurl + '?appid=' + appid + '&q=' + urllib.parse.quote(q) + '&from=' + fromLang + \'&to=' + toLang + '&salt=' + str(salt) + '&sign=' + sign# 建立会话，返回结果try:httpClient = http.client.HTTPConnection('api.fanyi.baidu.com')httpClient.request('GET', myurl)# response是HTTPResponse对象response = httpClient.getresponse()result_all = response.read().decode("utf-8")result = json.loads(result_all)trans_result = result['trans_result'][0]['dst']except Exception as e:print(e)finally:if httpClient:httpClient.close()return trans_resultif __name__ == '__main__':a = 'Customer Not Available & Mobile not reachable Customer Not Available & Mobile not reachable by SR: ANIL KUMAR (170435) (117510), MobileNo: 9996366909'print(trans_lang(a))

3、chrome翻译api：
