如何告诉 Googletrans 忽略某些部分？

Question

我想使用googletrans 来使用 Google 翻译 API。但是，其中有一些字符串是变量名：

User "%(first_name)s %(last_name)s (%(email)s)" has been deleted.

如果我通过 googletrans 使用它，我会得到

from googletrans import Translator
translator = Translator()
translator.translate(u'User "%(first_name)s %(last_name)s (%(email)s)" has been assigned.', src='en', dest='fr').text

我得到以下信息：

L'utilisateur "% (first_name) s% (last_name) s (% (email) s)" a été affecté.

但是，“%(first_name) s% (last_name)s (%(email)s)”引入了一些字符串。有没有解决的办法？我已经试过了：

u'User "<span class="notranslate">%(first_name)s %(last_name)s (%(email)s)</span>" has been assigned.'

Answer 1

其实你需要如下格式：

(3 '_' before) (string) (2 '_' after)
Like: ___%s__

Answer 2

Googletrans 似乎没有改变，例如 __1__。所以你可以在翻译前把%(first_name)s换成__0__，把%(last_name)s换成__1__等等，然后再把变量还原。这里的代码可以做到这一点：

from googletrans import Translator
import re

translator = Translator()
txtorig = u'User "%(first_name)s %(last_name)s (%(email)s)" has been assigned.'

# temporarily replace variables of format "%(example_name)s" with "__n__" to
#  protect them during translate()
VAR, REPL = re.compile(r'%\(\w+\)s'), re.compile(r'__(\d+)__')
varlist = []
def replace(matchobj):
  varlist.append(matchobj.group())
  return "__%d__" %(len(varlist)-1)
def restore(matchobj):
  return varlist[int(matchobj.group(1))]

txtorig = VAR.sub(replace, txtorig)
txttrans = translator.translate(txtorig, src='en', dest='fr').text
txttrans = REPL.sub(restore, txttrans)

print(txttrans)

结果如下：

L'utilisateur "%(first_name)s %(last_name)s (%(email)s)" a été attribué.
