• 单个文件打开 QFileDialog.getOpenFileName()

• 文件夹选取     QFileDialog.getExistingDirectory()

• 文件保存         QFileDialog.getSaveFileName()

• from PyQt5 import QtWidgets
  from PyQt5.QtWidgets import QFileDialog
   
  class MyWindow(QtWidgets.QWidget):
      def __init__(self):
          super(MyWindow,self).__init__()
          self.myButton = QtWidgets.QPushButton(self)
          self.myButton.setObjectName("myButton")
          self.myButton.setText("Test")
          self.myButton.clicked.connect(self.msg)
   
      def msg(self):
          directory1 = QFileDialog.getExistingDirectory(self,"选取文件夹", "C:/")                                 #起始路径
          print(directory1)
   
          fileName1, filetype = QFileDialog.getOpenFileName(self, "选取文件","C:/","All Files (*);;Text Files (*.txt)")   #设置文件扩展名过滤,注意用双分号间隔
          print(fileName1,filetype)
   
          files, ok1 = QFileDialog.getOpenFileNames(self, "多文件选择", "C:/", "All Files (*);;Text Files (*.txt)")
          print(files,ok1)
   
          fileName2, ok2 = QFileDialog.getSaveFileName(self, "文件保存", "C:/","All Files (*);;Text Files (*.txt)")
   
  if __name__=="__main__":  
      import sys  
    
      app=QtWidgets.QApplication(sys.argv)  
      myshow=MyWindow()
      myshow.show()
      sys.exit(app.exec_())
