PyQt5内嵌浏览器

class MainWindow(QMainWindow):
    def __init__(self):
        super(MainWindow, self).__init__()
        self.setWindowTitle('加载外部网页的例子')
        self.setGeometry(5,30,1355,730)
        self.browser=QWebEngineView()
        #加载外部的web界面
        self.browser.load(QUrl('https://www.baidu.com'))
        self.setCentralWidget(self.browser)

if __name__ == '__main__':
    app=QApplication(sys.argv)
    win=MainWindow()
    win.show()
    app.exit(app.exec_())

当出现PyQt5 中 No module named 'PyQt5.QtWebEngineWidgets'的解决办法：

转至低版本的PyQt5

pip install PyQt5==5.10.1
