第一个是以人类可读格式指示文件类型的标签,而第二个是用于匹配文件名的模式。 multiple:布尔值,指示用户是否可以选择多个文件。 defaultextension:如果未明确给出文件名,则添加到文件名的扩展名。 在我们的示例中,我们将初始目录设置为根文件夹和自定义标题。在我们的文件类型元组中,我们有以下三个有效选择:使用.txt...
Tkinter 模块(Tk 接口)是 Python 的标准 Tk GUI 工具包的接口 . Tk 和 Tkinter 可以在大多数的 Unix 平台下使用,同样可以应用在 Windows 和 Macintosh 系统里。 Tk8.0 的后续版本可以实现本地窗口风格,并良好地运行在绝大多数平台中。 wxPython: wxPython 是一款开源软件 是Python 语言的一套优秀的 GUI 图形库...
In the example, we have generated 4 labels with alphabets ‘A‘, ‘B‘, ‘C‘, and ‘D‘ with some values. But columns are not arranged properly. So, by using a drag method, we would be able to sort the columns as we required. Output: After running the following code, we come u...
