… __str__

Hello, and thanks for your contribution!

I'm a bot set up to make sure that the project can legally accept your contribution by verifying you have signed the PSF contributor agreement (CLA).

Unfortunately we couldn't find an account corresponding to your GitHub username on bugs.python.org (b.p.o) to verify you have signed the CLA (this might be simply due to a missing "GitHub Name" entry in your b.p.o account settings). This is necessary for legal reasons before we can look at your contribution. Please follow the steps outlined in the CPython devguide to rectify this issue.

You can check yourself to see if the CLA has been received.

Thanks again for your contribution, we look forward to reviewing it!

ericvsmith

In addition to the test you have, I'd like to see some tests with classes that define format, and with format and str.

jason-curtis · 2019-07-02T20:06:14Z

Test coverage is now something like:

overrides `__str__`	overrides `__format__`	mixin/"pure" `Enum`	asserts `str`	asserts `format`	test name
y	n	pure	y	y	`test_str_override_enum` (new)
n	y	pure	y	y	`test_format_override_enum` (new)
y	y	pure	y	y	`test_str_and_format_override_enum` (new)
y	n	mixin	y	y	`test_str_override_mixin` (new)
y	y	mixin	y	y	`test_str_and_format_override_mixin` (new)
n	y	mixin	y (new)	y	`test_format_override_mixin` (renamed)
n	n	mixin	n	y	`test_format_enum_date etc`
n	n	mixin	y	n	`test_multiple_mixin`
y	n	pure	y	n	`TestFlag.test_str`

Just a couple changes needed.

Also, please add yourself to the ACKS file.

Thank you for working on this!

Please backport using cherry_picker on command line.

Is that something I can do, or something you'll need to do @ethanfurman?

@thatneat If you know your way around git and GitHub feel free! My git-fu is very weak. In case you haven't seen it, the dev guide is here:

https://devguide.python.org/

jason-curtis · 2019-07-04T20:25:45Z

It looks like I don't have the permissions I need to use the cherry_picker tool. I almost got there, but it requires push access to the repo. I didn't even have to get too dirty in git-land. All I had to do was:

pip install cherry_picker --user
cherry_picker 2f19e82fbe98ce86bcd98a176328af2808b678e8 3.7

Then, manually edit Misc/ACKS to remove the merge markers but keep the additions (search for ">>>>" and delete the 3 lines that don't belong), then

git add Misc/ACKS
cherry_picker --continue # This is where I was blocked by not being allowed to push to the 3.7 branch

# This one didn't even appear to require a manual merge; it was just good to go.

Maybe this change should be mentioned in the 3.11 what's new. It has the potential of breaking a lot of code.
