##On the system that has access to internet
The pip download command lets you download packages without installing them:
pip download -r requirements.txt
(In previous versions of pip, this was spelled pip install --download -r requirements.txt.)
##On the system that has no access to internet
Copy over the downloaded packages to this system and then you can use
pip install --no-index --find-links /path/to/download/dir/ -r requirements.txt
to install those downloaded modules, without accessing the network.

- on peut créer des modules installable avec
pip - on peut créer des executables qui n'ont pas besoin de python sur la machine cible
Pour le premier point, voir le cours.
Pour le deuxième, on peut utiliser pyinstaller. Il y a un exemple dans "tape_en_cours". On peut également utiliser un wrapper pour pyinstaller : auto py to exe, voici un tutoriel en francais : https://www.docstring.fr/formations/convertir-un-script-en-fichier-executable/avec-auto-py-to-exe-sur-windows-1523/
