1、选择文件夹并显示

from PyQt5 import QtWidgetsdirectory = QtWidgets.QFileDialog.getExistingDirectory(None, "选取文件夹", "./")  # 起始路径
print(directory)

2、选择文件

from PyQt5 import QtWidgetsdirectory, _ = QtWidgets.QFileDialog.getOpenFileName(None,  "选取文件","./", "All Files (*);;Text Files (*.txt)")
#当窗口非继承QtWidgets.QDialog时，self需替换成 None

3、选择多个文件

from PyQt5 import QtWidgetssave_file_path,_ = QtWidgets.QFileDialog.getOpenFileNames(None, "选取多个文件", "./","All Files (*);;Text Files (*.txt)")
#当窗口非继承QtWidgets.QDialog时，self需替换成 None

4、设置保存文件路径

from PyQt5 import QtWidgetsdirectory, _ = QtWidgets.QFileDialog.getSaveFileName(None, "设置路径","./","All Files (*);;Text Files (*.txt)") 
#当窗口非继承QtWidgets.QDialog时，self需替换成 None

简单测试：

from PyQt5.QtWidgets import QApplication, QFileDialogapp = QApplication([])save_file_path,_ = QFileDialog.getOpenFileName(None,  "选取文件","./", "All Files (*);;Text Files (*.txt)")
if save_file_path:print("文件将被保存在：", save_file_path)
else:print("用户取消了保存操作")app.exec_()
