@pavoljuhas , @dstrain115 ruff check fix is missing a few type updates but suggests to fix manually, such as follows

Cirq/cirq-core/cirq/value/type_alias.py

Line 27 in e9a592d

TParamKey = Union[str, sympy.Expr]

I am not sure if these can be updated to variable: X | Y . Please suggest.

To have reproducible results, the best is to create a new environment in the same way as in the CI workflow here

Cirq/.github/workflows/ci.yml

Lines 82 to 85 in e9a592d

	- name: Install mypy
	run: pip install -r dev_tools/requirements/mypy.env.txt
	- name: Type check
	run: check/mypy

I have pushed badf4ca for the final issues detected by ruff.

@pavoljuhas Thank you. I'll create a new environment.

@pavoljuhas Thank you. I'll create a new environment.
