我试图保存在mysql数据库中随机生成的代码，但它只保存第一个字符，我尝试了不同的方法，但没有工作。这是我的密码：

try:
    error = None
    with mysql.connection.cursor() as cursor:
        passwordd = ''
        if request.method == 'GET' or 'POST':
            for n in range(0, 8):
                x = random.randint(0, 9)
                if x <= 3:
                    passwordd += str(random.choice('abcdefghijklmnopqrstuvxyz'))
                elif x <= 6:
                    passwordd += str(random.choice('abcffsddddd'))
                else:
                    passwordd += str(random.randrange(0, 9))
                    return passwordd
                sql = "INSERT INTO generatedcode(password) VALUES (%s)"
                cursor.execute(sql, (passwordd))
                mysql.connection.commit()
