ui文件转换为py文件后的处理

在用Designer生成.ui文件后，需要对此文件进行转换，转为python可识别的.py文件。
下面是一个转换后的例子：

from PyQt5 import QtCore, QtGui, QtWidgets


class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(1101, 709)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.toolButton = QtWidgets.QToolButton(self.centralwidget)
        self.toolButton.setGeometry(QtCore.QRect(120, 250, 37, 18))
        self.toolButton.setObjectName("toolButton")
        self.pushButton = QtWidgets.QPushButton(self.centralwidget)
        self.pushButton.setGeometry(QtCore.QRect(360, 330, 75, 23))
        self.pushButton.setObjectName("pushButton")
        self.radioButton = QtWidgets.QRadioButton(self.centralwidget)
        self.radioButton.setGeometry(QtCore.QRect(250, 470, 89, 16))
        self.radioButton.setObjectName("radioButton")
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 1101, 23))
        self.menubar.setObjectName("menubar")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)

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

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
        self.toolButton.setText(_translate("MainWindow", "..."))
        self.pushButton.setText(_translate("MainWindow", "PushButton"))
        self.radioButton.setText(_translate("MainWindow", "RadioButton"))

在调用的时候直接插入固定的代码即可：

import sys

'''
这里是上面自动生成的代码

'''



def show_mainwindow():
    app = QtWidgets.QApplication(sys.argv)
    mainwindow = QtWidgets.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(mainwindow)
    mainwindow.show()
    sys.exit(app.exec_())


if __name__ == "__main__":
    show_mainwindow()
