save button: IndexError

[Maryan]

So my app can successfully export to csv file and import it. But when I try to save the data into the DB I'm getting error.
One note: when I import the csv file there is extra one empty row.

IndexError: list index out of range

Here is my function for save buton

        def savedb():
            if messagebox.askyesno('Confirm', 'Are you sure you want to save the data into the Database?'):
                try:
                    
                    for i in mydata:
                        sid = i[0]
                        fname = i[1]
                        surname = i[2]
                        idc = i[3]
                        query = "INSERT INTO student_questioner(student_id, student_name, student_surname, student_card, student_score) VALUES (NULL, ?, ?, ?,?) "
                        cur.execute(query, (sid,fname, surname, idc))
                    con.commit()
                    clear()
                    messagebox.showinfo('Data Saved', 'Data has been saved to the database!')
                except EOFError as a:
                    messagebox.showerror(a)
            else:
                return False
