Hi,
It irks me that I know of no simple cross-platform way to print
colored terminal text from Python.
As I understand it, printing ANSI escape codes (as wrapped nicely by
module termcolor and others) works on Macs and *nix, but only works on
Windows if one has installed the ANSI.SYS device drive

Think about using the subprocess module. There are calls made just for

-
subprocess.call = call(*popenargs, **kwargs)
Run command with arguments. Wait for command to complete, then
return the returncode attribute.
