I have created a wrapper for displaying messages with ArcPy and IDLE (as that is all I have available to myself due to certain circumstances) as I frequently use both to test and develop new tools. However I find myself repeatingprint statements andarcpy functions to display feedback.

Unfortunately, it has to be in compatible with Python 2.7.
