如何基于pycharm写出一个界面同时显示两个文件夹的图片

下面是一个基于PyQt5的示例代码，可以同时显示两个文件夹中的图片：

import os
from PyQt5 import QtCore, QtGui, QtWidgets

class MainWindow(QtWidgets.QMainWindow):
    def __init__(self, parent=None):
        super(MainWindow, self).__init__(parent)
        self.setWindowTitle("Image Viewer")

        self.left_folder = QtWidgets.QTreeView()
        self.left_folder.setRootIsDecorated(False)
        self.left_folder.setSortingEnabled(True)
        self.left_folder.setModel(QtGui.QFileSystemModel())
        self.left_folder.selectionModel().selectionChanged.connect(self.left_folder_selection_changed)

        self.left_image = QtWidgets.QLabel()
        self.left_image.setAlignment(QtCore.Qt.AlignCenter)

        self.right_folder = QtWidgets.QTreeView()
        self.right_folder.setRootIsDecorated(False)
        self.right_folder.setSortingEnabled(True)
        self.right_folder.setModel(QtGui.QFileSystemModel())
        self.right_folder.selectionModel().selectionChanged.connect(self.right_folder_selection_changed)

        self.right_image = QtWidgets.QLabel()
        self.right_image.setAlignment(QtCore.Qt.AlignCenter)

        main_widget = QtWidgets.QWidget()
        main_layout = QtWidgets.QHBoxLayout()
        main_layout.addWidget(self.left_folder)
        main_layout.addWidget(self.left_image)
        main_layout.addWidget(self.right_folder)
        main_layout.addWidget(self.right_image)
        main_widget.setLayout(main_layout)
        self.setCentralWidget(main_widget)

    def left_folder_selection_changed(self, selected, deselected):
        index = selected.indexes()[0]
        file_model = QtGui.QFileSystemModel()
        file_model.setRootPath(index.data())
        file_model.setNameFilters(["*.jpg", "*.png"])
        file_model.setNameFilterDisables(False)
        self.left_image.setPixmap(QtGui.QPixmap(file_model.filePath(index)))

    def right_folder_selection_changed(self, selected, deselected):
        index = selected.indexes()[0]
        file_model = QtGui.QFileSystemModel()
        file_model.setRootPath(index.data())
        file_model.setNameFilters(["*.jpg", "*.png"])
        file_model.setNameFilterDisables(False)
        self.right_image.setPixmap(QtGui.QPixmap(file_model.filePath(index)))

if __name__ == '__main__':
    app = QtWidgets.QApplication([])
    win = MainWindow()
    win.show()
    app.exec_()

这个界面中有两个QTreeView控件，分别显示两个文件夹的目录结构，当选择某个文件时，会在相应的QLabel控件中显示该文件的图片。可以通过在left_folder_selection_changed()和right_folder_selection_changed()方法中设置过滤条件来控制只显示jpg和png格式的图片。
