我在這個網站上找到了答案，就像這樣

self.cur.execute("SELECT GlId FROM gradelevel WHERE GradNumber = ? ", (greadn,)) 
            rows = self.cur.fetchone()
            if rows:
                GreadLvl_ID = rows[0] 
            else:
                self.cur.execute("INSERT INTO gradelevel(GradNumber)VALUES(?)",(greadn,))
                self.cur.execute("SELECT GlId FROM gradelevel WHERE GradNumber = ? ", (greadn,)) 
                rows = self.cur.fetchone()
                GreadLvl_ID = rows[0]
                greadID = self.cur.lastrowid


            self.cur.execute("SELECT CID FROM classnumber WHERE ClassNumb = ? AND GradID = ?", (claasn, GreadLvl_ID))
            rows1 = self.cur.fetchone()
            if rows1:

                classnID = self.cur.lastrowid


            self.cur.execute("SELECT StID FROM studintinfo WHERE StudintID = ? AND ClassID = ?", (studinti, class_ID))
