本文研究的主要是PyQt5 打開文件對話框QFileDialog的代碼示例，具體如下。

單個文件打開 QFileDialog.getOpenFileName()
多個文件打開 QFileDialog.getOpenFileNames()
文件夾選取 QFileDialog.getExistingDirectory()
文件保存 QFileDialog.getSaveFileName()

實例代碼：

from PyQt5 import QtWidgetsfrom PyQt5.QtWidgets import QFileDialogclass 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,                  "選取文件夾",                  "./")                 #起始路徑    print(directory1)    fileName1, filetype = QFileDialog.getOpenFileName(self,                  "選取文件",                  "./",                  "All Files (*);;Text Files (*.txt)")  #設置文件擴展名過濾,注意用雙分號間隔    print(fileName1,filetype)    files, ok1 = QFileDialog.getOpenFileNames(self,                  "多文件選擇",                  "./",                  "All Files (*);;Text Files (*.txt)")    print(files,ok1)    fileName2, ok2 = QFileDialog.getSaveFileName(self,                  "文件保存",                  "./",                  "All Files (*);;Text Files (*.txt)")if __name__=="__main__":   import sys   app=QtWidgets.QApplication(sys.argv)   myshow=MyWindow()  myshow.show()  sys.exit(app.exec_())
