请帮我构造一个用Qtdesigner编写的学生就业指导的pyqt5界面的代码

以下是用 Qt Designer 编写的学生就业指导的 Pyqt5 界面的代码：

from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(800, 600)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.label = QtWidgets.QLabel(self.centralwidget)
        self.label.setGeometry(QtCore.QRect(260, 40, 281, 31))
        font = QtGui.QFont()
        font.setPointSize(16)
        self.label.setFont(font)
        self.label.setObjectName("label")
        self.line = QtWidgets.QFrame(self.centralwidget)
        self.line.setGeometry(QtCore.QRect(50, 90, 701, 16))
        self.line.setFrameShape(QtWidgets.QFrame.HLine)
        self.line.setFrameShadow(QtWidgets.QFrame.Sunken)
        self.line.setObjectName("line")
        self.label_2 = QtWidgets.QLabel(self.centralwidget)
        self.label_2.setGeometry(QtCore.QRect(120, 120, 91, 21))
        font = QtGui.QFont()
        font.setPointSize(12)
        self.label_2.setFont(font)
        self.label_2.setObjectName("label_2")
        self.lineEdit = QtWidgets.QLineEdit(self.centralwidget)
        self.lineEdit.setGeometry(QtCore.QRect(220, 120, 321, 31))
        self.lineEdit.setObjectName("lineEdit")
        self.label_3 = QtWidgets.QLabel(self.centralwidget)
        self.label_3.setGeometry(QtCore.QRect(120, 180, 91, 21))
        font = QtGui.QFont()
        font.setPointSize(12)
        self.label_3.setFont(font)
        self.label_3.setObjectName("label_3")
        self.lineEdit_2 = QtWidgets.QLineEdit(self.centralwidget)
        self.lineEdit_2.setGeometry(QtCore.QRect(220, 180, 321, 31))
        self.lineEdit_2.setObjectName("lineEdit_2")
        self.label_4 = QtWidgets.QLabel(self.centralwidget)
        self.label_4.setGeometry(QtCore.QRect(120, 240, 91, 21))
        font = QtGui.QFont()
        font.setPointSize(12)
        self.label_4.setFont(font)
        self.label_4.setObjectName("label_4")
        self.lineEdit_3 = QtWidgets.QLineEdit(self.centralwidget)
        self.lineEdit_3.setGeometry(QtCore.QRect(220, 240, 321, 31))
        self.lineEdit_3.setObjectName("lineEdit_3")
        self.pushButton = QtWidgets.QPushButton(self.centralwidget)
        self.pushButton.setGeometry(QtCore.QRect(330, 320, 121, 41))
        font = QtGui.QFont()
        font.setPointSize(12)
        self.pushButton.setFont(font)
        self.pushButton.setObjectName("pushButton")
        self.line_2 = QtWidgets.QFrame(self.centralwidget)
        self.line_2.setGeometry(QtCore.QRect(50, 400, 701, 16))
        self.line_2.setFrameShape(QtWidgets.QFrame.HLine)
        self.line_2.setFrameShadow(QtWidgets.QFrame.Sunken)
        self.line_2.setObjectName("line_2")
        self.label_5 = QtWidgets.QLabel(self.centralwidget)
        self.label_5.setGeometry(QtCore.QRect(120, 430, 91, 21))
        font = QtGui.QFont()
        font.setPointSize(12)
        self.label_5.setFont(font)
        self.label_5.setObjectName("label_5")
        self.textEdit = QtWidgets.QTextEdit(self.centralwidget)
        self.textEdit.setGeometry(QtCore.QRect(220, 470, 321, 61))
        self.textEdit.setObjectName("textEdit")
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 26))
        self.menubar.setObjectName("menubar")
        self.menuFile = QtWidgets.QMenu(self.menubar)
        self.menuFile.setObjectName("menuFile")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)
        self.actionOpen = QtWidgets.QAction(MainWindow)
        self.actionOpen.setObjectName("actionOpen")
        self.actionSave = QtWidgets.QAction(MainWindow)
        self.actionSave.setObjectName("actionSave")
        self.menuFile.addAction(self.actionOpen)
        self.menuFile.addAction(self.actionSave)
        self.menubar.addAction(self.menuFile.menuAction())

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
        self.label.setText(_translate("MainWindow", "学生就业指导"))
        self.label_2.setText(_translate("MainWindow", "姓名："))
        self.label_3.setText(_translate("MainWindow", "性别："))
        self.label_4.setText(_translate("MainWindow", "学院："))
        self.pushButton.setText(_translate("MainWindow", "提交"))
        self.label_5.setText(_translate("MainWindow", "备注："))
        self.menuFile.setTitle(_translate("MainWindow", "文件"))
        self.actionOpen.setText(_translate("MainWindow", "打开"))
        self.actionSave.setText(_translate("MainWindow", "保存"))

这段代码定义了一个名为 Ui_MainWindow 的 Pyqt5 界面类，其中包含了各种控件，如标签、文本框、按钮等等。我们可以将这个类作为主窗口的子类，从而实现一个完整的用户界面。
