💡 Explanation: If join() is a method on a string, then it can operate on any iterable (list, tuple, iterators). If it were a method on a list, it'd have to be implemented separately by every type. Also, it doesn't make much sense to put a string-specific method on a generic...

在tkinter中,根窗口只能有一个,也就是通过Tk()方法创建的实例对象。如果需要创建多个窗口该怎么办呢?那就需要使用另一个控件——Toplevel 在第一篇概述的主要控件列表中,我已经列出来了 Toplevel 顶层 类似框架,为其他的控件提供单独的容器 实际上该控件可以当做一个根窗体去使用,API是相同的,想要实现多个窗口,必...
