googletrans Error: 'NoneType' Object Has No Attribute 'Group'

Initial Problem

Attempts to use the googletrans package have resulted in the following error:

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

Root Cause and Impact

This error suggests that the googletrans package is encountering issues with its token acquisition mechanism. As a result, translation operations are failing.

Potential Solution 1: Update to Alpha Version

An official alpha version of googletrans has been released that addresses this issue:

pip install googletrans==3.1.0a0

Example:

from googletrans import Translator
translator = Translator()
translation = translator.translate("Der Himmel ist blau und ich mag Bananen", dest='en')
print(translation.text) # 'The sky is blue and I like bananas'

Potential Solution 2: Specify Service URL

If the above update does not resolve the issue, try specifying the service URL manually:

from googletrans import Translator
translator = Translator(service_urls=['translate.googleapis.com'])
translator.translate("Der Himmel ist blau und ich mag Bananen", dest='en')

Alternative Option: google_trans_new Package

If the above fixes do not work, consider using the google_trans_new package as an alternative:

#pip install google_trans_new

from google_trans_new import google_translator
translator = google_translator()
translate_text = translator.translate('สวัสดีจีน', lang_tgt='en')
print(translate_text) # 'Hello china'
