[issue46376] PyMapping_Check returns 1 for list
Serhiy Storchaka added the comment: It is difficult to distinguish Mapping from Sequence because they have the same set of dunder methods. The difference is only in semantic -- __iter__ yields items for Sequence and keys for Mapping, __getitem__ gets an item by index (or a sequence by slice) for Sequence and value by key for Mapping. But semantic cannot be tested here. In these cases when both Sequence and Mapping are accepted but handled differently (like in the dict constructor) we test for existence of the "keys" method. It is not good, because it is not a dunder method, and therefore should be looked up at instance, not only at a type. -- ___ Python tracker <https://bugs.python.org/issue46376> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Serhiy Storchaka added the comment: Why __class_getitem__ was added in PurePath at first place? PurePath should not be a generic class, unlike to os.PathLike. For os.PathLike the type parameters represent the returning type of os.fspath() (either str or bytes), but the pathlib module only supports paths as strings, so no parametrization is needed. I think PurePath.__class_getitem__ should be removed. -- nosy: +gvanrossum, kj, serhiy.storchaka ___ Python tracker <https://bugs.python.org/issue46483> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue37295] Possible optimizations for math.comb()
Serhiy Storchaka added the comment: All this should be tested with the C implementation because relative cost of operations is different in C and Python. I have tested Raymond's idea about using iterative algorithm for small k. $ ./python -m timeit -s 'from math import comb' "comb(3329023, 3)" recursive: Mean +- std dev: 173 ns +- 9 ns iterative: Mean +- std dev: 257 ns +- 13 ns $ ./python -m pyperf timeit -s 'from math import comb' "comb(102571, 4)" recursive: Mean +- std dev: 184 ns +- 10 ns iterative: Mean +- std dev: 390 ns +- 29 ns $ ./python -m pyperf timeit -s 'from math import comb' "comb(747, 8)" recursive: Mean +- std dev: 187 ns +- 10 ns iterative: Mean +- std dev: 708 ns +- 39 ns Recursive algorithm is always faster than iterative one for k>2 (they are equal for k=1 and k=2). And it is not only because of division, because for perm() we have the same difference. $ ./python -m pyperf timeit -s 'from math import perm' "perm(2642247, 3)" recursive: Mean +- std dev: 118 ns +- 7 ns iterative: Mean +- std dev: 147 ns +- 8 ns $ ./python -m pyperf timeit -s 'from math import perm' "perm(65538, 4)" recursive: Mean +- std dev: 130 ns +- 9 ns iterative: Mean +- std dev: 203 ns +- 13 ns $ ./python -m pyperf timeit -s 'from math import perm' "perm(260, 8)" recursive: Mean +- std dev: 131 ns +- 10 ns iterative: Mean +- std dev: 324 ns +- 16 ns As for the idea about using a table for fixed k=20, note that comb(87, 20) exceeds 64 bits, so we will need to use a table of 128-bit integers. And I am not sure if this algorithm will be faster than the recursive one. We may achieve better results for lesser cost if extend Mark's algorithm to use 128-bit integers. I am not sure whether it is worth, the current code is good enough and cover the wide range of cases. Additional optimizations will likely have lesser effort/benefit ratio. -- ___ Python tracker <https://bugs.python.org/issue37295> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue46426] Improve tests for the dir_fd argument
New submission from Serhiy Storchaka : There is a flaw in tests for the dir_fd argument in test_posix. All these tests open a current directory as dir_fd, so all paths are relative to the current directory. They will pass in case of the following errors: 1. dir_fd, src_dir_fd or dst_dir_fd are completely ignored. 2. The meaning of src_dir_fd and dst_dir_fd is opposite. The proposed PR rewrites these tests. It is ensure that directory file descriptors refer to directories different from the current directory, and that src_dir_fd and dst_dir_fd refer to different directories, and that all tested filenames are unique, so files cannot be confused with existing diles in different directories. Also add context manager open_dir_fd() in test.support.os_helper. It may be helpful in other tests for the dir_fd argument. -- components: Tests messages: 410882 nosy: serhiy.storchaka priority: normal severity: normal status: open title: Improve tests for the dir_fd argument type: behavior versions: Python 3.10, Python 3.11, Python 3.9 ___ Python tracker <https://bugs.python.org/issue46426> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue46393] Generate frozenset constants when explicitly appropriate
Serhiy Storchaka added the comment:
As Steven have noted the compiler-time optimization is not applicable here
because name frozenset is resolved at run-time.
In these cases where a set of constants can be replaced with a frozenset of
constants (in "x in {1,2,3}" and in "for x in {1,2,3}") the compiler does it.
And I don't think there is an issue which is worth changing the language.
Creating a frozenset of constants is pretty rare, and it is even more rare in
tight loops. The most common cases (which are pretty rare anyway) are already
covered.

[issue46187] Optionally support rounding for math.isqrt()
Serhiy Storchaka added the comment: Is i, rem = isqrt_rem(n) i + (rem != 0) better than (isqrt(n<<2) + 1) >> 1 or n and isqrt(n-1) + 1 ? As for use cases, there were few cases in my experience when I needed the ceiling square root, mostly in simple experiments in REPL, but it was so rary, and workarounds satisfied me. So it would be a nice to have feature which I would use perhaps once in a year or two years, but can live without it. And I do not want to pay a cost of significantly complicating API or slowing down isqrt(). -- nosy: +serhiy.storchaka ___ Python tracker <https://bugs.python.org/issue46187> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue34931] os.path.splitext with more dots

[issue34931] os.path.splitext with more dots
Serhiy Storchaka added the comment:
There are other issues with the documentation of splitext().
1. It uses term "extension" (it is even a part of function name), but it is
vague and usually does not include a period. On Windows the extension of
"python.exe" is "exe", not ".exe". On Unix term "suffix" is commonly used,
".exe" is a suffix. It is also used in pathlib. I suggest to replace
"extension" with "suffix".
2. It is not specified that only the part of the last path component is
included in the suffix, and leading periods of the last path component are
ignored, not just leading periods of the path. So splitext('mail.dir/') ==
('mail.dir/', '') and splitext('/home/user/.etc') is ('/home/user/.etc', '').
It is not documented that splitext() works with multi-component paths at all.

[issue46167] Parse assert (x == y, "Descriptive text") as statement params instead of a tuple
Serhiy Storchaka added the comment: For very long expression or very long message you can add parentheses around the expression or message. Black will format it as: assert ( very very long expression ), ( "very very long " "message" ) With the proposed feature it will be: assert ( very very long expression, "very very long " "message", ) It saves one line, but the border between an expression and a message is blur. Since they are separated by a comma at the end of line and all lines have the same indentation it looks less readable to me. Note also that Black adds a comma after message. -- ___ Python tracker <https://bugs.python.org/issue46167> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue46167] Parse assert (x == y, "Descriptive text") as statement params instead of a tuple
Serhiy Storchaka added the comment: It does not need any change in parser, it can be done in the code generator which currently explicitly warns about such ambiguity. Although it needs changes in formal grammar which will be more complex. But what is a benefit? What is an advantage of writing assert (thing, description) instead of assert thing, description ? -- nosy: +gvanrossum, serhiy.storchaka ___ Python tracker <https://bugs.python.org/issue46167> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

And more errors can be found with:
$ find -name '*.rst' -exec egrep --color -i '\ban +[qwrtpsdfghjklzxcvbnm]' '{}'
+
$ find -name '*.rst' -exec egrep --color -i '\ba +[eioa]' '{}' +
It is worth to check also:
$ find -name '*.rst' -exec egrep --color -i '\ban +[yu]' '{}' +
$ find -name '*.rst' -exec egrep --color -i '\ba +[yu]' '{}' +
Most of them should be correct, but there may be some new errors.

[issue46157] Typo in JSON documentation
Serhiy Storchaka added the comment:
Thank you Kumar.
These errors were found with the following one-liners:
$ find -name '*.rst' -exec egrep --color -i '\ban
+:[a-z:]+:`[qwrtpsdfghjklzxcvbnm]' '{}' +
$ find -name '*.rst' -exec egrep --color -i '\ba +:[a-z:]+:`[eyuioa]' '{}' +
They produce a lot of false positive results because of signatures and
different reading of initial "y" and "u" (and "o", but there are no such cases
here).
