LGTM in general.

Only needed to document this change:

Add the versionchanged directive in the pprint module documentation.
Add a news entry in Misc/NEWS.d (use blurb).
Add an entry in the What's New document.
Add your name in Misc/ACKS if it is not there yet.

Thanks for working on this! Mostly LGTM. I've left a few comments.

FWIW, code is almost always more readable when limited to one action per line. Among other things, it makes it much easier to understand what's happening (especially when parentheses are involved).

Suggested change

self.assertEqual(pprint.pformat(types.SimpleNamespace()), "namespace()")

formatted = pprint.pformat(

types.SimpleNamespace())

self.assertEqual(formatted, "namespace()")

Personally I like to separate the 3 parts (setup, actual-thing-to-test, assertions) with blank lines, for further readability, but that's more personal preference:

Suggested change

self.assertEqual(pprint.pformat(types.SimpleNamespace()), "namespace()")

ns = types.SimpleNamespace()

formatted = pprint.pformat(ns)

self.assertEqual(formatted, "namespace()")

I do not think that adding an empty line after every line of code will make the code more readable. Empty lines should be used for separating logical sections of the code.

This code is consistent with the code in this file and looks clear to me. I do not think that any changes are needed.

I followed most of @ericsnowcurrently's suggestions, but without the empty lines and without textwrap.dedent to be consistent with the rest of the file and I think it has made the test more clear.

ericsnowcurrently · 2019-06-24T15:43:37Z

As before, I recommend one action per line.

Suggested change

self.assertEqual(pprint.pformat(n, width=60), """\

formatted = pprint.pformat(ns, width=60)

self.assertEqual(formatted, """\

...and separating the key sections of the test.

Suggested change

self.assertEqual(pprint.pformat(n, width=60), """\

formatted = pprint.pformat(ns, width=60)

self.assertEqual(formatted, """\

@serhiy-storchaka I ended up removing the write = stream.write optimization. If you do think it is worth it in this case, please let me know and I'll bring it back (properly this time, as pointed out by @ericsnowcurrently).

Add a test for a SimpleNamespace subclass.

@serhiy-storchaka ofc it was because of subclassing. Glad you're here to review! :D

serhiy-storchaka

Thank you Carl. LGTM, just fix an indentation in docs.

Suggested change

Added support for pretty-printing :class:`types.SimpleNamespace`.

Added support for pretty-printing :class:`types.SimpleNamespace`.

ericsnowcurrently

Thanks for working to resolve our various comments!

Other than one small thing, LGTM.

ericsnowcurrently · 2019-06-25T21:19:35Z

If this check is for the sake of subclasses then I'd recommend being explicit about it:

Suggested change

if cls_name == "SimpleNamespace":

if type(object) is _types.SimpleNamespace:

@ericsnowcurrently I attempted to make it more clear what the class-name-if-statement is about.

Thank you very much to the both of you for the fast, high quality responses. It was a good experience :-)

LGTM. I'm approving this, but also leaving one last comment. :) (feel free to ignore)

Thanks again for doing this.

ericsnowcurrently · 2019-06-26T19:56:25Z

Thanks for updating this. It's more clear now (as a reader).

And better. Checking the class by comparing the class name to a string is a bit wonky :D Thanks for pointing out, what I was actually doing.

ericsnowcurrently · 2019-06-26T20:01:16Z

Thanks for adding a comment here. That helps. :) FWIW, the following might be more clear:

# The SimpleNamespace repr has "namespace" instead of the class name, so # we do the same here. For subclasses we just use the class name.

Tried improving it, should be clear now
