Debian currently supports two Python stacks, one for Python 3
|
||
and one for Python 2. The long term goal for Debian is to
|
||
reduce this to one stack, dropping the Python 2 stack at some
|
||
time.
|
||
</p><p>
|
||
<a class="ulink" href="https://www.python.org/dev/peps/pep-0404/" target="_blank">PEP 404</a> states that no more major Python 2 releases
|
||
are planned, although the latest released minor version 2.7
|
||
will see some extended support, documented in
|
||
<a class="ulink" href="https://www.python.org/dev/peps/pep-0466/" target="_blank">PEP 466</a>.

Packages in Debian should use Python 3 if Python 3 is
|
||
supported. New packages should use Python 3 from the initial
|
||
upload, new upstream versions for existing packages should
|
||
use Python 3 if the new upstream version supports it.
|
||
</p><div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem"><p>
|
||
Programs should use Python 3, and should not be packaged
|
||
for Python 2 as well. Python 3 should be used for the
|
||
packaging if the packaging scripts use Python.
|
||
</p></li><li class="listitem"><p>
|
||
Python libraries, if they support Python 3, should be always
|
||
packaged for Python 3. If an application supports only Python
|
||
2, the Python libraries for that application should also be
|
||
packaged for Python 2.

</p></li><li class="listitem"><p>
|

Existing Python 2 libraries should not be dropped before
|
||
the last reverse dependency is removed.
