Python 如何动态读取QLineEdit数据

我试图在PyQt5中动态创建标签和文本框，但是，我不知道当用户点击保存按钮时如何读取文本框中输入的数据。我的代码如下所示：

       self.setWindowTitle("Yaml --> Json")
       self.setGeometry(self.left, self.top, self.width, self.height)

       self.createLayout()
       vbox = QVBoxLayout()
       for i in range(0, len(self.listItems)):
           vbox.addWidget(QLabel(list(self.listItems.keys())[i]))
           vbox.addWidget(QLineEdit())
       vbox.addWidget(self.groupBox)
       self.setLayout(vbox)
       self.show()

   def createLayout(self):
       self.groupBox = QGroupBox()
       hboxLayout = QHBoxLayout()

       button = QPushButton("Save", self)
       button.setIcon(QtGui.QIcon("save.png"))
       button.setIconSize(QtCore.QSize(40, 40))
       button.setMinimumHeight(40)
       button.clicked.connect(self.ClickSave)
       hboxLayout.addWidget(button)

       button1 = QPushButton("Exit", self)
       button1.setIcon(QtGui.QIcon("exit.png"))
       button1.setIconSize(QtCore.QSize(40, 40))
       button1.setMinimumHeight(40)
       button1.clicked.connect(self.ClickExit)
       hboxLayout.addWidget(button1)

       self.groupBox.setLayout(hboxLayout)

   def ClickExit(self):
       print("Exited!!")
       sys.exit()

   def ClickSave(self):
       print("Saved!")```

您可以将稍后要访问的小部件分配给实例变量或将它们存储在列表中，例如

    self.line_edit_list = []
    for i in range(0, len(self.listItems)):
        vbox.addWidget(QLabel(list(self.listItems.keys())[i]))
        line_edit = QLineEdit()
        vbox.addWidget(line_edit)
        self.line_edit_list.append(line_edit)

    ....

    def ClickSave(self):
        for edit in self.line_edit_list:
            print(edit.text())
