It's exciting, but man there are lots of assumptions in native python built around the gil.

I've seen lists, etc. modified by threads assuming the gil locks for them. Testing this e2e for any production deployment can be a bit of a nightmare.

My company makes it super easy for me - we're just going to continue on python 2.7 and add this to the long list of reasons why we're not upgrading.

Please send help.

You may be pleased to know that PyPy's Python 2.7 branch will be maintained indefinitely, since PyPy is also written in Python 2.7. Also, if you can't leave CPython yet, ActivePython's team is publishing CPython 2.7 security patches.

We already have contracts in place to get security patches. That's usually the InfoSec team's problem anyway.

As a developer, my life gets hard due to library support. We manage internal forks of multiple open source projects just to make them python 2 compatible. A non-trivial amount of time is wasted on this, and we don't even have it available for public use. 🤷‍♂️

Why would you not be upgrading due to a new feature of python? You don't like new features or was that a badly wordered sentence?

Because using an exceedingly insecure version is cheaper until an inevitable compromise makes it expensive.

More work, more debt. The more debt you have the harder it is to let go.

Python 2.7 and iOS mobile programmers stuck on Objective-C could start a support group.
