| Two new versions of the language are currently in development: version
| 2.6, which retains backwards compatibility with previous releases; and
| version 3.0, which breaks backwards compatibility to the extent that

That change is however, the one most immediately visible to new 
programmers. Most of the other statements are pretty much unchanged.  In 
any case, 'print' is an easy-to-use facade over sys.stdout.write(), with 
default formatting.  If really concerned about it, start programs with
   import sys
   write = sys.stdout.write
and use that to write out explicitly formatted strings.  (Some people 
routinely do this for production code anyway.)
