Hi, Python » 3.5.0 Documentation » The Python Standard Library » 25. Graphical User Interfaces with Tk » states that "You can check that tkinter is properly installed on your system by running python -m tkinter from the command line; this should open a window demonstrating a simple Tk interface."
Having recently installed Python 3.5.0 I find that python -m tkinter produces: 'python' is not recognised as an internal or external command, operable program or batch file. Can you help, please? Thank you, Chris Harwood. -- https://mail.python.org/mailman/listinfo/python-list
