creation de service windows probleme de mise en forme class et def
bonjour debut en python, je voudrais creer un service qui enregistre dans un fichier les data recuperer par un lecteur RFID dans un fichier.
j'ai creer le fichier en python, quand je le lance via python il fonctionne bien.
j'ai recuperer les information pour creer un service sur ce model :https://www.gerbelotbarillon.com/python-win-service.php.
j'ai donc essayer de fusionner mon programme avec les class necessaire pour faire tourné mon service
voici mon fichier :
