Answer 1

This is a known, reported issue in the googletrans library's github page. Take a look there to see the status of the fix and potential work arounds: https://github.com/ssut/py-googletrans/issues.

According to the most recent comment, installing a different version, googletrans==4.0.0-rc1, appears to work, but with caveats:

fire17 commented 16 days ago
normal pip installation failed but uninstalled and reinstalled
googletrans==4.0.0-rc1
then worked :)
tho the object is wierd, i can access the translated text like

a = translator.translate("hi")
translated_text = a.__dict__()["text"]

Answer 2

It worked post re-installing googletrans

pip install googletrans==4.0.0-rc1
