I think I got the way to handle it but with small problem and probably at
unnecessary performance cost. If you're going to use it, be sure rewrite the
code and remove the lines which you don't need. Ad, test them, the code
below is only tested on py3.2, and may contains a lot of bugs even in py

Suppose we want to use the unittest from Python 2.7, but also want to
support Python 2.6,
what is the best way to do it?
The solution used now is to have in setup.py
if sys.version < '2.7':
tests_require.append('unittest2')
and then in every test file
try:
import unittest2 as unittes

Last week I was surprised to discover that there are Unicode characters that
aren't valid in an XML document. That is regardless of escaping (e.g. �)
and unicode encoding (e.g. UTF-8) - not every Unicode string can be stored in
XML. The valid characters are (as of XML 1.0) #x9 | #xA | #xD | [#x2

Hi,
I'm having problems getting a script that I wrote to check the unread Gmail

We're chuffed to announce the immediate availability of the second release
candidates for Python 2.6.8, 2.7.3, 3.1.5, and 3.2.3. The only change from the
first release candidates is the patching of an additional security hole.
The security issue fixed in the second release candidates is in the exp
