Sunsetting Python 2 is a bit of an issue for banks like JPMorgan

Well, they have the money to pay someone for support / back-porting security patches. I wonder what system they are running Python on as Red Hat is ok for a while.

This actually brings an interesting question on what other languages / systems they have used in the past and does Python represent a new lifetime concern given some of the older platforms.

I wonder if the transition could be so hard for some large installations that they move entire codebases to a different language. I guess not, because if they could do that they’d have moved to python 3.

What should happen here, is that banks should either pay to accelerate transition to Python 3 to meet the deadline, or they should pay to fund somebody to continue to maintain Python 2.

What will happen here, is banks won't see any issue, because their Python 2 software still works after the sunset. It'll be business as usual, and there will eventually be security incidents due to running Python 2.

If they only use it internally and not on external-facing sites then the security issue is somewhat less urgent.
