End of support for python 2.7?

Question

Is there a known date/timeframe when python 2.7 will not be supported any more in favor of python 3?

Answer 1

In May 2010, Word of God was that patchlevel releases for Python 2.7 will probably be made for at least 6 years.

So, maybe 2016, probably later.

Edit: Pushed back to 2020. See the revision to PEP 373, linked to in other answers.
