Ce script écrit Python permet d’envoyer des photos extraites via Picasa sur un site FTP, le tout avec une interface graphique GTK2.
C’est mon premier développement « important » en Python – il m’a permis notamment de voir:
- Interface graphique et GTK2 et utilisation de Glade.
- Utilisation de la librairie ftplib.
- Mécanique des threads dans une IHM.
Il reste fortement améliorable, notamment en ce qui concerne la gestion des exceptions (try…except).
