anyone tested the various Python scripts against Python 3?
I think we have been trying to avoid this. I think I did do some stuff with
lyx2lyx, running it with whatever that flag is that warns you about Python 3
incompatibilities, but that is all I did. Plainly, we need to do this with
all of our scripts.

in my limited experience -
Writing python code running in both 2.6 and 3 is possible, for 2.5 and
3.x it can turn out pretty hard. How to:

If we can't control the environment, python 2 is not a bad choice to
stick for a while:

automated code conversion might help at some point:

I committed two simple fixes for configure.py. Here is what 2to3 says

So we have two print statements that need fixing, and one call to map().
For map(), I think the change mentioned works in 2.x anyway, right? So
that's easy.
What's the minimum Python version we require these days? If 2.6, then we
can handle the print stuff by importing print_function from __future__.
If not, then we'll have to futz around a bit and perhaps do something like:
def ourprint(s):
if sys.version_info[0] == 3:
print(s)
else:
sys.write(s + '\n')
Will that work? Or do we have to put different declarations of
ourprint() in different modules and import one or the other depending
upon which version we are running? Alternatively, we could just use
sys.write and be done with it.
