        self.pushButton.clicked.connect(self.close)

（8）退出系统：

self.pushButton_7.clicked.connect(self.close)

四、实验过程

1、添加学生：

首先添加五个学生如下面一组图。

2、删除学生：

（1）按序号删除：

数据承接上文，操作内容如下面一组图。

（2）按姓名删除：

此时我们再添加一组同名数据康神二，并进行按姓名删除，如下面一组图。

3、查找学生：

（1）按序号查找：

数据承接上文，操作内容如下面一组图。

（2）按姓名查找：

此时我们添加一组新数据康神四，如下面一组图。

4、修改学生：

（1）按序号修改：

数据承接上文，操作内容如下面一组图。

（2）按姓名修改：

数据承接上文，操作内容图下面一组图。

5、排名：

数据承接上文，操作内容如下图。

6、显示学生：

数据承接上文，操作内容如下面一组图。

7、退出：

五、实验总结

熟悉了Qt Designer创建界面，实现了界面和逻辑分离。
掌握了信号，槽函数和信号与槽的绑定。
掌握了PyQt5编程中的对话框QDialog、各类控件、主窗口QMainWindow。
对窗口编程有了初步了解，今后还需要多加学习复习。
