Backwards Compatibility part 4... (Python recipe) by Barry Walker
ActiveState Code (http://code.activestate.com/recipes/577903/)

Some example lines to add to any test code you write that work from Python 1.4.0 to 3.2.2 on various platforms.

It is all Public Domain and you can do with it as you please...

I really don't care how you vote and/or rate this as I try to write Python code for my usage to work on the platforms and versions inside the code.

Some people will know this but very MANY won't and there will be more to come that involve platform and version compatibility...

(Watch out for word wrapping, etc...)

# Backwards compatibility for text mode Python 1.4.0 to 3.2.2...

# Some simple lines that work for all these versions on the

# classic AMIGA, E-UAE, PCLinuxOS 2009, Debian 6.0.0, Windows XP and

# Vista and WinUAE. Note, classic AMIGAs and derivatives only reach

# Python version 2.4.6. AROS goes to version 2.5.2.

# Python versions checked against, 1.4.0, 2.0.1, 2.4.2, 2.5.2, 2.6.1

# 2.6.6, 2.7.2, 3.0.1, 3.1.3 and 3.2.2.

# These are to go along with these pointers...

This function......

>>> print(somestring)

......seems to have been around for the vast majority of needs for Python from at least Version 1.4.0.

Well it goes without saying that the "same" function......

>>> print(somenumber)

......is equally valid and has also been around for at least the same length of time.

Therefore within limits "print(something)" is valid irrespective of platform or version.

Again everything looks exactly the same on screen on all versions and platforms inside the code.

So long as one keeps to the example ideas given in the uploads so far, text mode Python will give the same results on screen on all the platforms and relevant versions applied to said platforms.

That is all for now for printing to a text mode Python window. Good eh!
