[Tkinter-discuss] Opening a .py that uses Tkinter on OS X pops open a console window

[Jonathan Frankel]

Okay, so I was instantiating differently. But now...when I run that
code (I'm running exactly what you posted), I get:

invalid command name "console"

inside the console, and the console stays open. If I do it without
catching the error, I get the additional info:

...
    self.tk.call('console','hide')
_tkinter.TclError: invalid command name "console"

and the whole thing crashes. This happens both on OS X and WinXP...

I can't even find which module this 'call' method originate from, so I
can't find out how it works. Does anyone know about tk.call?
