python - Hide console when py-file only (no pyw) [ANKI add-on] -

i adjust music fiddler add-on anki srs windows users. anki runs add-ons with ending .py, not pyw. there way hide console automatically pops when run code.

if not, there way no unselect console windows (i have click on main anki windows after every 5 seconds because console closed again in selection).

the command use far opening windows example: os.system('"nircmd.exe changesysvolume"'+ change)

the complete code below console runs nircmd.exe , number of volume units system sound should change. there possibility adjust code?

it seems using subprocess module instead of os.system solve problem. please see how avoid console window .pyw file containing os.system call? , how hide console when use os.system() or subprocess.call()?.
