Nope. No consensus.

I wouldn't say any particular Linux distribution is appreciably better
for Python development than another. I would suggest using a version of
a Linux distribution that supports a recent Python release (e.g. 3.9 or
3.10).

That's not an expression; it is an assignment statement.
The right-hand side is an expression. It will (at the top level) create
