I\'m using Win XP and Python 2.5. Is there a way in Python to modify font size when print to CMD window?
No, you can't change that, as far as I know. Luckly, nobody on windows uses the console anyway, so I advise you to move to a GUI library instead.
With your own GUI window, you can configure the font and layout as much as you want, include buttons, images, animations, menus, etc...
You can use ctypes
to access the necessary windows calls to change the font (including the size of the font) of the console. See my answer to another question for a code example.
You should create a desktop link to cmd.exe and set/change the layout properties (e.g. to window size 120*40 or appropriate). Start your program in this console windows (python.exe yourprogram.py).
