Hi folks,

I was going to write this post for a while because all sorts of myths
periodically come up on this list about python 3. I don't think the
posters mean to spread false information on purpose, they simply are
not aware of the facts.

My list is surely incomplete, please feel free to post your favorite
misconception about python 3 that people periodically state, claim or
ask about.

1. Print statement/function creates incompatibility between 2.x and 3.x!

Certainly false or misleading, if one uses 2.6 and 3.x the
incompatibility is not there. Print as a function works in 2.6:

Python 2.6.2 (r262:71600, Aug 21 2009, 12:23:57)
[GCC 4.4.1 20090818 (Red Hat 4.4.1-6)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> print( 'hello' )
hello
>>> print 'hello'
hello
>>>


2. Integer division creates incompatibility between 2.x and 3.x!

Again false or misleading, because one can get the 3.x behavior with 2.6:

Python 2.6.2 (r262:71600, Aug 21 2009, 12:23:57)
[GCC 4.4.1 20090818 (Red Hat 4.4.1-6)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> 6/5
1
>>> from __future__ import division
>>> 6/5
1.2


Please feel free to post your favorite false or misleading claim about python 3!

Cheers,
Daniel
