• 单个文件打开 QFileDialog.getOpenFileName()
  多个文件打开 QFileDialog.getOpenFileNames()

• 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_())
