is it possible, for example, to make the text that appears as output on the command line appear in a certain colour using python?
Yes. But the answer depends on your platform. In windows you can use the command-line COLOR command. Here's how:
Microsoft Windows XP [Version 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.
C:\Documents and Settings\Administrator>COLOR /?
Sets the default console foreground and background colors.
attr Specifies color attribute of console output
Color attributes are specified by TWO hex digits -- the first
corresponds to the background; the second the foreground. Each digit
can be any of the following values:
0 = Black 8 = Gray
1 = Blue 9 = Light Blue
2 = Green A = Light Green
3 = Aqua B = Light Aqua
4 = Red C = Light Red
5 = Purple D = Light Purple
6 = Yellow E = Light Yellow
7 = White F = Bright White
If no argument is given, this command restores the color to what it was
when CMD.EXE started. This value either comes from the current console
window, the /T command line switch or from the DefaultColor registry
The COLOR command sets ERRORLEVEL to 1 if an attempt is made to execute
the COLOR command with a foreground and background color that are the
Example: "COLOR fc" produces light red on bright white
C:\Documents and Settings\Administrator>COLOR 52
I used COLOR 52 to set the background to Purple with the foreground (text) to Green (ugliest combo I could think of?)
To do this in Python simply use os.system('COLOR 52') . If you're looking for greater resolution you'll need to look into curses; however that's not readily available for Windows. You could instead create your own highly-stylized GUI with something like wxPython or GTK
