[issue37688] The results from os.path.isdir(...) an Path(...).is_dir() are not equivalent for empty path strings.

Kirill Balunov added the comment: I am reading "equivalence" too strictly (like "as a substitute"), because this is part of the documentation :) and I agree that in ordinary speech I would use it rather in the sense of “similar”. In order to make sure, that

[issue37688] The results from os.path.isdir(...) an Path(...).is_dir() are not equivalent for empty path strings.

Kirill Balunov added the comment: I understand the reasons, I only say that it does not correspond to my perception of their equivalence, because: os.path.isdir('') != os.path.isdir('.') while: Path('').is_dir() == Path('.').is_dir() and I can confirm that some libraries rely

[issue37688] The results from os.path.isdir(...) an Path(...).is_dir() are not equivalent for empty path strings.

New submission from Kirill Balunov : In the documentation it is said that os.path.isdir(...) an Path(...).is_dir()are equivalent substitutes. https://docs.python.org/3/library/pathlib.html#correspondence-to-tools-in-the-os-module But they give different result for empty path strings

[issue32455] PyCompile_OpcodeStackEffect() and dis.stack_effect() are not particularly useful

Kirill Balunov <kirill.balu...@gmail.com> added the comment: Sorry if this doesn't fit this issue and needs a separate one. Since Python switched to 2 byte wordcode, all opcodes which do not imply an argument, technically have it - augmented with 0. So it is convenient to iterat

[issue33326] Convert collections (cmp_op, hasconst, hasname and others) in opcode module to more optimal type

New submission from Kirill Balunov <kirill.balu...@gmail.com>: The opcode module contains several collections: `cmp_op` `hasconst` `hasname` `hasjrel` ... which are only used for `in` checks. At the same time, they are stored as `list`s and `cmp_op` as tuple. Both these types are not o
