Avec la prise en charge de Python 3.8 depuis #2432 , il est peut-être temps d'abandonner officiellement Python 2.7 ? Nous sommes en 2020 =)

P/S : C'est déjà sorti de notre flux de travail CI depuis un bon moment.

Si #2504 est fusionné, il reste encore quelques éléments de Python 2 :

• [x] Le plugin de test dans nltk/test/doctest_nose_plugin.py qui ignore le premier u des littéraux Unicode et s'assure que les comparaisons d'égalité réussissent. Si l'on veut supprimer ce plugin, il faudra s'assurer que tous les littéraux Unicode sont supprimés des tests.
• [ ] web/dev/local_testing.rst mentionne toujours Python 2 et devrait être mis à jour.
• [ ] les mentions de Python 2.7 et Python 2.6 dans le code doivent vérifier si elles sont toujours pertinentes
