Python itself doesn't have this option. In IDLE, a hack would be to switch between writing to sys.stdout and sys.stderr -- these are displayed in different colors. But this only works in IDLE, and your program would print everything in the same boring color on all other platforms (plus, the interspersing of stdout and stderr depends on the buffering options for both files unless you use flush() a lot). > Also it would be nice when using regular expressions to color matches a > different color than the text that doesn't match. Can different colors be > sent to the Idle output window? In general, when you find this need, you should consider building a real GUI using Tkinter (the same toolkit used to create IDLE) or wxPython, but those have serious learning curves. I find Fredrik Lundh's tutorials and examples on effbot.org very helpful; there's also a book, Python and Tkinter Programming by John E. Grayson, which you may find second-hand on the web. If you're on Unix (including Linux), the curses module will let you do this; it also has a bit of a learning curve but not quite as much as the typical GUI toolkit. Most terminal emulators (but not IDLE) also support using escape sequences for specifying colors (this is how curses works). Googling for ANSI escapes should get you the basic idea (ESC is "\033" in Python). This should work on Windows in CMD windows and on Unix in most terminal programs (e.g. xterm). I think support in remote terminal programs (e.g. putty on Windows) is spotty; you might end up with only being able to choose between regular and bold.
