三大Python翻译神器再也不用担心学不好英语
导语
hello everyone! I'm kimiko!
Miss me???
嘿！中秋结束了，开始正式营业给大家继续送福利啦！
中秋在家发现：家里的小孩子在最后上学那天开始赶作业了！果然每个孩子的童年都是一样的！哈哈哈啊~
看了一眼侄女儿正在写英语翻译题目， 啊这一看不得了题目写的乱七八糟！！！
这让我有点儿上头啊，刚巧直接给我姐说了：‘'‘这英语还要加强学习撒'http://www.cppcns.com
老姐说：‘'回家我也不会教不了，学校的也没学好，一句完整的句子都讲不出来.......‘“
那肯定是拿上我30米的鼠标键盘，开始敲代码！这款中英文翻译神器，小孩子学习英文很轻松啊~回家就给我侄女儿装上电脑了！

你是不是也经常遇到这些问题：往下看！！今天教大家写一款三大翻译神器，你值得拥有！
环境安装：python3.6、pycharm2021,以及自带的模块。
pip install -i https://pypi.douban.com/simple/ requests pip install -i https://pypi.douban.com/simple/ pyqt5
简单的界面可优化哈：
class Translator(QWidget):
def __init__(self, parent=None, **kwargs):
super(Translator, self).__init__(parent)
self.setWindowTitle('三大翻译软件')
self.setWindowIcon(QIcon('data/icon.jpg'))
self.Label1 = QLabel('原文')
self.Label2 = QLabel('译文')
self.LineEdit1 = QLineEdit()
self.LineEdit2 = QLineEdit()
self.translateButton1 = QPushButton()
self.translateButton2 = QPushButton()
self.translateButton3 = QPushButton()
self.translateButton1.setText('百度翻译')
self.translateButton2.setText('有道翻译')
self.translateButton3.setText('谷歌翻译')
self.grid = QGridLayout()
self.grid.setSpacing(12)
self.grid.addWidget(self.Label1, 1, 0)
self.grid.编程客栈addWidget(self.LineEdit1, 1, 1)
self.grid.addWidget(self.Label2, 2, 0)
self.grid.addWidget(self.LineEdit2, 2, 1)
self.grid.addWidget(self.translateButton1, 1, 2)
self.grid.addWidget(self.translateButton2, 2, 2)
self.grid.addWidget(self.translateButton3, 3, 2)
self.setLayout(self.grid)
self.resize(400, 150)
self.translateButton1.clicked.connect(lambda : self.translate(api='baidu'))
self.translateButton2.clicked.connect(lambda : self.translate(api='youdao'))
self.translateButton3.clicked.connect(lambda : self.translate(api='google'))
self.bd_translate = baidu()
self.yd_translate = youdao()
self.gg_translate = google()
def translate(self, api='baidu'):
word = self.LineEdit1.text()
if not word:
return
if api == 'baidu':
results = self.bd_translate.translate(word)
elif api == 'youdao':
results = self.yd_translate.translate(word)
elif api == 'google':
results = self.gg_translate.translate(word)
else:
raise RuntimeError('Api should be <baidu> or <youdao> or <google>...')
self.LineEdit2.setText(';'.join(results))
三大翻译之一：百度翻译类。
class baidu():
def __init__(self):
self.session = requests.Session()
self.session.cookies.set('BAIDUID', '19288887A223954909730262637D1DEB:FG=1;')
self.session.cookies.set('PSTM', '%d;' % int(time.time()))
self.headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.102 Safari/537.36'
}
self.data = {
'from': '',
'to': '',
'query': '',
'transtype': 'translang',
'simple_means_flag': '3',
'sign': '',
'token': '',
'domain': 'common'
}
self.url = 'https://fanyi.baidu.com/v2transapi'
self.langdetect_url = 'https://fanyi.baidu.com/langdetect'
def translate(self, word):
self.data['from'] = self.detectLanguage(word)
self.data['to'] = 'en' if self.data['from'] == 'zh' else 'zh'
self.data['query'] = word
self.data['token'], gtk = self.getTokenGtk()
self.data['token'] = '6482f137ca44f07742b2677f5ffd39e1'
self.data['sign'] = self.getSign(gtk, word)
res = self.session.post(self.url, data=self.data)
return [res.json()['trans_result']['data'][0]['result'][0][1]]
def getTokenGtk(self):
url = 'https://fanyi.baidu.com/'
res = requests.get(url, headers=self.headers)
token = re.findall(r"token: '(.*?)'", res.text)[0]
gtk = re.findall(r";window.gtk = ('.*?');", res.text)[0]
return token, gtk
def getSign(self, gtk, word):
evaljs = js2py.EvalJs()
js_code = js.bd_js_code
js_code = js_code.replace('null !== i ? i : (i = window[l] || "") || ""', gtk)
evaljs.execute(js_code)
sign = evaljs.e(word)
return sign
def detectLanguage(self, word):
data = {
'query': word
}
res = self.session.post(self.langdePDEWETtect_url, headers=self.headers, data=data)
return res.json()['lan']
三大翻译之二：有道翻译类。
class youdao():
def __init__(self):
self.headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36',
'Referer': 'http://fanyi.youdao.com/',
'Cookie': 'OUTFOX_SEARCH_USER_ID=-481680322@10.169.0.83;'
}
self.data = {
'i': None,
'from': 'AUTO',
'to': 'AUTO',
'smartresult': 'dict',
'client': 'fanyideskweb',
'salt': None,
'sign': None,
'ts': None,
'bv': None,
'doctype': 'json',
'version': '2.1',
'keyfrom': 'fanyi.web',
'action': 'FY_BY_REALTlME'
}
self.url = 'http://fanyi.youdao.com/translate_o?smartresult=dict&smartresult=rule'
def translate(self, word):
ts = str(int(time.time()*10000))
salt = ts + str(int(random.random()*10))
sign = 'fanyideskweb' + word + salt + '97_3(jkMYg@T[KZQmqjTK'
sign = hashlib.md5(sign.encode('utf-8')).hexdigest()
bv = '5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36'
bv = hashlib.md5(bv.encode('utf-8')).hexdigest()
self.http://www.cppcns.comdata['i'] = word
self.data['salt'] = salt
self.data['sign'] = sign
self.data['ts'] = ts
self.data['bv'] = bv
res = requests.post(self.url, headers=self.headers, data=self.data)
return [res.json()['translateResult'][0][0].get('tgt')]
三大翻译之三：Google翻译类。
class google():
def __init__(self):
self.headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36',
}
self.url = 'https://translate.google.cn/translate_a/single?client=t&sl=auto&tl={}&hl=zh-CN&dt=at&dt=bd&dt=ex&dt=ld&dt=md&dt=qca&dt=rw&dt=rm&dt=ss&dt=t&tk={}&q={}'
def translate(self, word):
if len(word) > 4891:
raise RuntimeError('The length of word should be less than 4891...')
编程客栈 languages = ['zh-CN', 'en']
if not self.isChinese(word):
target_language = languages[0]
else:
target_language = languages[1]
res = requests.get(self.url.format(target_language, self.getTk(word), word), headers=self.headers)
return [res.json()[0][0][0]]
def getTk(self, word):
evaljs = js2py.EvalJs()
js_code = js.gg_js_code
evaljs.execute(js_code)
tk = evaljs.TL(word)
return tk
def isChinese(self, word):
for w in word:
if '\u4e00' <= w <= '\u9fa5':
return True
return False
效果如下：中英文各一句哈！
总结
每天进步一点点！记得“三连哦~爱你”，坚持学习！！！
