PEP 572 and Future

[ichabod801]

No one is forcing the devs to use the assignment expression.

I don't think this is a realistic statement. First of all, if it becomes part of the language, it will be used in code, and that may be code that the devs have to deal with. Not all of the code you use is your own. Second of all, their bosses may force them to use it. I've worked places with coding style manuals. You can either follow them or have it held against you at your performance review.
