How about:
In Python 2, 'print' was a statement and did not require
parenthesis around its argument. In Python 3 'print' has
been changed to a function and now, like all functions,
requires parenthesis around its arguments:
python 2: print arg1, arg2,...
python 3: print (arg1, arg2,...)
Did you seriously not understand how someone, reading a tutorial or
book written for Python 2, might be confused when a specific simple
syntax he/she was explicitly told works, doesn't work? Not everyone
new to and starting to explore Python appreciates (?!) the major
compatibility breaks that occurred between Py2 and Py3. One would
expect that in such a situation, the new user would certainly question
his/her code rather than something changed in Python.
Or better than changing the message, how about leaving it alone and
simply responding helpfully rather than snappily and condescending to
inevitable confusion that surely must have been anticipated when the
Python developers chose to make this change.
It's no wonder that some people (often women) who don't like contention,
find this list rather hostile.
