python 利用qt 实现 账号密码注册功能

新手一枚，请勿喷，有需要优化的地方还请帮忙指出

我用的是txt文件来储存接收的账号密码

建立好py文件后，先自定义槽函数 要注意的是我没有用os 模块去新建txt,读者记得新建一个txt.文件，然后将下面的代码文件名修改即可。或者用os 模块去完善也行

def lj(self): #自定义槽函数 该功能是接收两个控件文本然后写入文本格式.txt
        bz=self.lineEdit.text()
        li=self.lineEdit_2.text()
      
        mz=open("我爱高圆圆.txt","w")
        
        mz.write("账号:"+bz+"n")
        mz.write("密码:"+li+"n")
      

然后就是绑定槽函数 将自己定义的函数和pushButton按钮连接与绑定

代码如下

  self.pushButton.clicked.connect(self.lj)

完整代码如下
