Code for reload windows services

[buran]

It will catch any exception that is raised when you try to execute the code inside try block. In this case

        service = psutil.win_service_get(service_name)
        return service.as_dict()

In my opinion you should catch only psutil.NoSuchProcess error, raised when no service with that name exists. I really don't think it's possible to get any other error from that code, but even if there is some other error, it's better to get the full traceback in order to debug it easier.

Also, is there any specific reason why you return the service as dict and not as Service object?

So

import os
import datetime
import psutil
import win32serviceutil
 
 
def get_service(service_name):
    try:
        return psutil.win_service_get(service_name)
    except psutil.NoSuchProcess:
        return None
 
 
if __name__ == '__main__':
    LOOKUP_SERVICE = 'Audiosrv'
    service = get_service(LOOKUP_SERVICE)
 
    if service:
        print("service trouvé.")
        if service.status() == 'runnig':
            print("service est en cours de fonctionnement")
        else:
            print("service est arreté")
            win32serviceutil.StartService(LOOKUP_SERVICE)
            print("le service a été demarré")
            try:
                os.mkdir(r'C:\Ariane\Logs_script_vision') # on windows back-slash in path may create problems. use raw string or forward slash
            except FileExistsError: # catch specifi error consistent with the msg you print
                print("Dossier logs déja existant")
            finally:
                with open(r"C:\Ariane\Logs_script_vision\Visionlogs.txt", "a") as fichier:
                    fichier.write(f"Le fichier vision a été relancé par notre script le :{datetime.datetime.now().ctime()}\n")
    else:
        print("service not found")

now, because your function is only wrapper around psutil function, you can possibly shorten the code further

import os
import datetime
import psutil
import win32serviceutil
  
  
LOOKUP_SERVICE = 'Audiosrv'

try:
    service = psutil.win_service_get(LOOKUP_SERVICE)
except psutil.NoSuchProcess:
    print("service not found")
else:
    print("service trouvé.")
    if service.status() == 'runnig':
        print("service est en cours de fonctionnement")
    else:
        print("service est arreté")
        win32serviceutil.StartService(LOOKUP_SERVICE)
        print("le service a été demarré")
        try:
            os.mkdir(r'C:\Ariane\Logs_script_vision') # on windows back-slash in path may create problems. use raw string or forward slash
        except FileExistsError: # catch specifi error consistent with the msg you print
            print("Dossier logs déja existant")
        finally:
            with open(r"C:\Ariane\Logs_script_vision\Visionlogs.txt", "a") as fichier:
                fichier.write(f"Le fichier vision a été relancé par notre script le :{datetime.datetime.now().ctime()}\n")
