   def __init__(self, args):
           win32serviceutil.ServiceFramework.__init__(self, args)
           self.hWaitStop = win32event.CreateEvent(None, 0, 0, None)          

   def SvcStop(self):
           self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)

Use either slashes (/), raw strings, or double backslashes:

                    file_path = "D:/Tarang/Project/form1.py"
                    file_path = r"D:\Tarang\Project\form1.py"
                    file_path = "D:\\Tarang\\Project\\form1.py"
