STINNER Victor <vstin...@python.org> added the comment:
Oh wait, I'm now confused by the method names. In Python 3.10, the correct
names at:
* float.__getformat__() <= 4 underscores
* float.__set_format__() <= 5 underscores
It's even more confusing because the "set format" is only used in one place:
test_float, and test_float uses... __setformat__() (4 underscores).
A typo a was introduced in Python 3.7 by:
commit b5c51d3dd95bbfde533655fb86ac0f96f771ba7b

bpo-20185: Convert float object implementation to Argument Clinic. (#543)
Based on patch by Vajrasky Kok.
Since Python 3.7, the 4 "set format" tests are simply skipped!
$ ./python -m test -v test_float
(...)
test_getformat (test.test_float.FormatFunctionsTestCase) ... skipped 'requires
__setformat__'
test_setformat (test.test_float.FormatFunctionsTestCase) ... skipped 'requires
__setformat__'
(...)
test_double_specials_dont_unpack (test.test_float.UnknownFormatTestCase) ...
skipped 'requires __setformat__'
test_float_specials_dont_unpack (test.test_float.UnknownFormatTestCase) ...
skipped 'requires __setformat__'
(...)
Moreover, unittest.mock supports mocking __setformat__() (4 underscores).
