how to create .bat file to run sikuli script , program language is python

hi ,all
here is my code:

    def subMain(self):
        fName = 'proc'
        #print detailed error log information
        logMsg = 'Class[%(cName)s] Function[%(fName)s] is start.' %{'cName': self.CNAME, 'fName': fName}
        self.mylog.write_log("subMain start")
        #execute function
        SikuliBaseClass.stepExecute(self, self.getParameter)
        SikuliBaseClass.stepExecute(self, self.copyWorkFile)
        SikuliBaseClass.stepExecute(self, self.renameFile)
        SikuliBaseClass.stepExecute(self, self.updTime)
        SikuliBaseClass.stepExecute(self, self.openSAP)
        SikuliBaseClass.stepExecute(self, self.sMICM)
        SikuliBaseClass.stepExecute(self, self.dbADmin)
        #print detailed error log information
        logMsg = 'Class[%(cName)s] Function[%(fName)s] is end.' %{'cName': self.CNAME, 'fName': fName}
        self.mylog.write_log("subMain end")

    # 終了関数
    #fixed code
    def end(self):
        fName = 'end'
        #print detailed error log information
        logMsg = 'Class[%(cName)s] Function[%(fName)s] is start.' %{'cName': self.CNAME, 'fName': fName}
        self.mylog.write_log(logMsg)
        #print detailed error log information
        logMsg = 'Class[%(cName)s] Function[%(fName)s] is end.' %{'cName': self.CNAME, 'fName': fName}
        self.mylog.write_log(logMsg)

task = testforNWP()
task.subMain()
