2023-07-30: I had to install version 4.0.0rc1, not the default version (see this and this Stackoverflow answer, and this Github discussion)
$ sudo pip install googletrans==4.0.0rc1
Translate a German sentence to english:
from googletrans import Translator
translator = Translator()
t = translator.translate(
'Kinder, das Essen wird kalt!',
src ='de',
dest='en'
)
print(t.text)
