There are a couple more things to do here, I think:

• the Python version in .flake8
• the arguments to pyupgrade in .pre-commit-config.yaml

I will convert it to a draft, handle those things, and also continue to look for any other places

If you notice anything else let me know

Looks like we can drop the dataclasses dep as the marker (python = "<3.7") makes it a no-op.

I don't have time to look into this, but I also suspect this line can be dropped as the types should be in the stdlib now. I may be wrong, so please look into it before making that change.

• Dropped dataclasses
  • poetry-core: Also already dropped dataclasses in Deprecate Python 3.6 poetry-core#263
• types-dataclasses: removed

@branchvincent: Thank you

Rebased.

Can you approve running on python-poetry/poetry-core#263?

@branchvincent

P.S.

Any preference on how to navigate this? I can merge the commits into mine or re-do them myself.

Unfortunately I don't have access yet 😓 , I've just started helping here. I'll see if I can find someone who does

Thanks for checking, but it's fine as is! I only have it as a requirement for another project

I believe there's one more version-gated block we can remove:

poetry/src/poetry/utils/pip.py

Lines 58 to 69 in 28d05d0

	if sys.version_info < (3, 7) and not is_wheel:
	# Under certain Python3.6 installs vendored pip wheel does not contain
	# zip-safe pep517 lib. In this cases we create an isolated ephemeral virtual
	# environment.
	with ephemeral_environment(
	executable=environment.python, with_pip=True, with_setuptools=True
	) as env:
	return environment.run(
	*env.get_pip_command(),
	*args,
	env={**os.environ, "PYTHONPATH": str(env.purelib)},
	)
