Hi Rob

Thanks for your reply.

From http://legacy.python.org/download/, I could see that the current production releases are Python 3.4 and Python 2.7.6\.

Since we use python for some our legacy applications, we don't want to switch to Python 3.0 right now. Moreover, since Python 2.6 is not supported anymore, we want to upgrade to Python 2.7.

Do you suggest I should use Python 2.7.12 which is the latest version in 2.7 series? I picked up 2.7.6, since it was listed as production release and assumed it is the most stable version.

Thanks

Sesha

I'm not sure - if you're going to run with old, custom, builds of
Python, you're probably best served by testing comprehensively for
this yourself.

That said, I have to presume that the error you're getting is from
some code that should be changed anyway, and will need to be changed
when you move to Python 3\. Please remember that Python 2.7.6 was
released in 2013 - there have been many security issues since then,
including some of the most egregious SSL issues ever, which should
prompt you to run the latest 2.7 branch (if you're unable to migrate
straight to 3.x.
