tkinter

[juliolop]

Before you it can create any windows Tk has to do a bunch of initialization stuff. The initialization stuff happens when you call tkinter.Tk(). Each executable should only call tkinter.Tk() once, and it has to be the first call to the tkinter module.

You probably want to make multiple windows. As Knight18 mentions you can do this by making multiple top level widgets (tkinter has a call for making a top level widget), or you can just create frames that do not have a parent and the window manager will supply a parent (make a window).

any example I can use for reference?
I'm just staring with tkinter
