I wrote a few lines using Translator function in Googletrans a few days ago. But I was trying to re-run those lines today and it popped a series of errors... I'm really confused by this. If you have experienced similar issue, please comment below. Any help is welcome!!

from googletrans import Translator
translator = Translator()
trans1 = translator.translate('Hello', dest = 'es')

The error I got is following:

AttributeError                            Traceback (most recent call last)

    181         tk = self.acquire(text)
    182         return tk

     57         r = self.session.get(self.host)
     58         # this will be the same as python code after stripping out a reserved word 'var'
---> 59         code = unicode(self.RE_TKK.search(r.text).group(1)).replace('var ', '')
     60         # unescape special ascii characters such like a \x3d(=)
     61         if PY3:  # pragma: no cover

AttributeError: 'NoneType' object has no attribute 'group'

I tried to do research on this error msg, but got nothing. What confused me the most is that this simple code worked perfectly fine 3 days ago. But when i open up this morning, i popped errors. Please help. Thank you so much!

Update py-googletrans/googletrans/gtoken.py like the following:

RE_TKK = re.compile(r'TKK=eval\(\'\(\(function\(\)\{(.+?)\}\)\(\)\)\'\);',
                    re.DOTALL)
RE_RAWTKK = re.compile(r'tkk:\'([^\']*)\'',re.DOTALL)

def __init__(self, tkk='0', session=None, host='translate.google.com'):
    self.session = session or requests.Session()
    self.tkk = tkk
    self.host = host if 'http' in host else 'https://' + host

def _update(self):
    """update tkk
    """
    # we don't need to update the base TKK value when it is still valid
    now = math.floor(int(time.time() * 1000) / 3600000.0)
    if self.tkk and int(self.tkk.split('.')[0]) == now:
        return

    r = self.session.get(self.host)

    rawtkk = self.RE_RAWTKK.search(r.text)
    if rawtkk:
        self.tkk = rawtkk.group(1)
        return

I got the solution below from this link.

Solution:

pip install git+https://github.com/BoseCorp/py-googletrans.git --upgrade

It worked perfectly for me!

Google has changed the way the token is created. There is no fix at the time of writing. You have to wait for googletrans to be updated.
