Mypy Release Notes

Next Release

Better narrowing

Mypy's implementation of narrowing has been substantially reworked. Mypy will now narrow more aggressively, more consistently, and more correctly. In particular, you are likely to notice new narrowing behavior in equality expressions (==), containment expressions (in), match statements, and additional expressions providing type guards.

Note that mypy (and other Python type checkers) do not model the potential for various non-local operations to invalidate narrowing assumptions. This means mypy may conclude that some of your code is unreachable and avoid further checking of it. The --warn-unreachable flag is useful for highlighting these cases. To reset narrowing, you can insert dummy reassignments, for instance var = var will reset all narrowing of var.attr.

Future work includes better narrowing on initial assignments, more narrowing to Literal types, and better checking of unreachable code.
