[Tkinter] how do I enter code into python

[Gribouillis]

You don't need lines 4,5,6,7. You can run the code by typing

Output:
python C:\Users\bob\test.py

in a terminal (use the correct path). You can also read this official documentation page: Using python on Windows

I'm not a windows user, but I know that you must not use a word processor that produces rich text to write python code. Wordpad may not be the correct tool. Install a real editor such as Notepad++ for this.
