python

1、ini参数设置
if not os.path.exists('setting.ini'):config = configparser.ConfigParser()config.add_section('Directories')config.set('Directories', 'last_used_directory', 'c:')with open('setting.ini', 'w') as configfile:config.write(configfile)
config = configparser.ConfigParser()
config.read('setting.ini')
last_used_directory = config.get('Directories', 'last_used_directory')

2、打开目录

def get_directory(self, last_used_directory):# root = tk.Toplevel()# root.withdraw()if not last_used_directory:last_used_directory = os.getcwd()directory = filedialog.askdirectory( initialdir=last_used_directory,)return directory

3、ui界面 简单界面，直接用代码实现

class MyApp(QApplication):FileName=""def __init__(self, argv):super().__init__(argv)self.loop = asyncio.get_event_loop()self.queue = asyncio.Queue()self.timer = QTimer()self.timer.timeout.connect(self.update_text)self.timer.start(100)self.initUI()def initUI(self):self.window = QWidget()self.log = QTextEdit()self.btnOpenFile = QPushButton('打开文件')self.btnOpenFile.clicked.connect(self.browseFile)self.btnOutputDir = QPushButton('设置输出目录')self.btnOutputDir.clicked.connect(self.setOutputDir)self.btnMake = QPushButton('生成语句')self.btnMake.clicked.connect(self.on_click)self.hbox = QHBoxLayout()# hbox = QHBoxLayout()self.hbox.addWidget(self.btnOpenFile)self.hbox.addWidget(self.btnOutputDir)self.hbox.addWidget(self.btnMake)self.vbox = QVBoxLayout()# vbox = QVBoxLayout()self.vbox.addLayout(self.hbox)self.vbox.addWidget(self.log)self.window.setLayout(self.vbox)self.window.setWindowTitle('数据处理')self.window.setGeometry(300, 300, 800, 1000)self.window.setWindowIcon(QIcon('icon.png'))self.window.show()

if __name__ == '__main__':import sysapp = MyApp(sys.argv)sys.exit(app.exec_())

4、复杂的界面，在qtcreator 添加文件-》 qt-》Qt Designer Form

直接加界面和槽函数，参考Pyqt5一小时速成精髓_哔哩哔哩_bilibili中的处理方法。
