[issue45892] Improve REPL with the underscore separators for int/float
New submission from Alex :
I often use to the Python REPL to perform some simple calculations (typically
some combinatorial or probabilities computation).
I believe it would be a nice improvement if the number displayed in the REPL
would be formatted as if f"{result:_}" was given (with the underscore
separators). For example:
>>> 36 ** 7
78_364_164_096
As I understand things:
* the REPL always shows the __repr__
* updating the __repr__ for int/float is a no-no for backward compatibility
reasons
If these assumptions are correct (please correct me if this is wrong), then I
guess this cannot be implemented, unless I missed something?

[issue25866] Reference 3. Data Model: miscellaneous minor cleanups on the word "sequence".
Alex added the comment: Hi, I've taken a look at these suggestions and the documentation and I've posted a patch to get things moving :) A couple of points about the suggested changes that I haven't included in the patch: 1) I think changing the documentation for __dir__() to say it can return an iterable needs some discussion. The documentation also says: "The ``__dir__`` function should accept no arguments, and return a list of strings that represents the names accessible on module. If present, this function overrides the standard :func:`dir` search on a module." And this should definitely be updated from "list of strings" to either "sequence of strings" or "iterable of strings". However, I'm not sure about updating docs to include "accidental" functionality - looking at the testing, news, and documentation from commit https://github.com/python/cpython/commit/3bbb72265411585e64a5d2ccb5ba51763f20e311 the intention was to allow __dir__ to return a sequence. I think updating the docs to say __dir__ should return an iterator would be a separate issue which would also include test enchancements, so I've left that change out of my patch and I've just corrected the line I've quoted above. 2) > The docs still say that the ABCs are in `collections` rather than `collections.abc`. I couldn't find an instance of this, it's probably been corrected at some point. Any thoughts on the above, the other suggestions, or the patch? -- keywords: +patch nosy: +alclarks Added file: https://bugs.python.org/file48713/issue25866.v1.patch ___ Python tracker <https://bugs.python.org/issue25866> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue38819] The redirect
New submission from Alex <2423067...@qq.com>:
Hi.
This bug I've found is about the redirect, you know, to redirect the standard
input/output stream. It's not really a bug, you can think of it as a feature.
The code is like this:
import sys
sys.stdout = open('redirect.txt','w')
print('hello world!') #Something you want to print
after you run it in the IDLE:
RESTART: XXX.py===
>>> print(1 + 1)
>>>
You will find you can't output as normal.
The version I choose for this issue is Python 3.8.0b4. However, I find this
problem is also exist in Python 3.7.5.
How to repair it?

[issue40100] Unexpected behavior when handling emoji under codec cp936
New submission from Alex <2423067...@qq.com>: Python 3.8.2 IDLE has an unexpected behavior. When I insert an emoji into IDLE like '๐'. Then I found I can't delete it(by typing backspace). When I type the left arrow then it became '๏ฟฝ๏ฟฝ'(U+FFFD). Then I type the left arrow again, then it is '๐' again! (When I use the delete button, or type the right button there aren't any bugs.) What's wrong? Also, when I have two emojis like '๐๐', I press delete button between them, nothing happens; when I delete on the right, both of them disappear!

[issue43399] xml.etree.ElementTree.extend does not work with iterators when using the Python implementation
New submission from Alex :
This issue is only visible when the C accelerator of ElementTree is *not* used.
It is the counterpart of the following issue on PyPy3:
https://foss.heptapod.net/pypy/pypy/-/issues/3181
>>> from xml.etree.ElementTree import Element
>>> r = Element("root")
>>> r.extend((Element(str(i)) for i in range(3)))
>>> print(list(r))
[]
When using the C accelerator, the list is not empty, as expected. In the Python
code, a check on the input empties the input iterator.
The fix is trivial (one-line change), so if you are interested I could open a
PR, which would be my first, so a good occasion to go through the devguide ;)
I understand that since Python3.3 the C accelerator is used by default, so I
would agree that this is not really a bug, and I can just fix it on PyPy side.

[issue41651] Pip: Wrong Showing of Progressbar when Downloading Modules
New submission from Alex <2423067...@qq.com>: 1. Abstract Command line in Windows the progress bar doesn't work like usual after about half of the downloading process. Another remarkble bug is the length of the progressbar seems to be lengthened. 2. Reason(my opinion) I noticed that this bug only happens when the rightmost character reaches the end of the cmd screen. I infer the reason of this bug from the phenomenon: when the progres bar is going to be lengthened, pip will delete the last line. Pip consider the line as an enter that the program output. However, the cmd consider the line as an enter whether it is output by the program or added by cmd itself because of the rightmost character reaches the end of the cmd screen. When pip make cmd delete the last line, pip want cmd to delete the whole progressbar, but cmd only deletes a part of the progressbar which are in the line 2. 3. Instance An instance of the bug, showing what happenred when upgrading pip via py -m pip install --upgrade pip. You can see the progress bar wasn't deleted completly.

[issue31087] asyncio.create_subprocess_* do not honor `encoding`
New submission from Alex:
Regardless of the value of `encoding`, StreamReaders returned for the
`asyncio.subprocess.Process`'s `stdout` and `stderr` would be in binary mode.
import sys
import asyncio
import subprocess
async def main():
sp = await asyncio.create_subprocess_exec('ls', '-la',
stdin=None,
stdout=subprocess.PIPE,
encoding='utf8')
await sp.wait()
data = await sp.stdout.read()
print(data)
print(isinstance(data, bytes))
loop = asyncio.get_event_loop()
loop.run_until_complete(main())
There are two naive solutions:
- `create_subprocess_*` could explicitly raise when provided any `encoding` and
`errors` (like it now does with `universal_newlines`).
- or implement encoding conversions for StreamReaders (and StreamWriters), and
forward those.
Of course it would be better to have conversions, but I don't know how those
will have to deal with decoding partially available data - e.g. returning in
the middle of surrogate pair, or having only half a codepoint for UTF16. There
should likely cache partial data to process at the next read, but this would
require rewriting codecs to support partial decode... seems like it's not that
easy :(

[issue36860] Inconsistent/Undocumented behavior with pathlib resolve and absolute on Windows
New submission from Alex :
Maybe I am doing something wrong here but:
On Windows 10:
> python --version
Python 3.7.1
> python
>>> from pathlib import Path
>>> Path("test.py").resolve()
WindowsPath('test.py')
>>> Path("test.py").absolute() # this is undocumented in
>>> https://docs.python.org/3.7/library/pathlib.html
WindowsPath('C:/Users/Name/Desktop/test.py')
On Ubuntu 18.04 LTS:
$ python3.7 --version
Python 3.7.3
$ python3.7
>>> from pathlib import Path
>>> Path("test.py").resolve()
PosixPath('/home/name/test.py')
>>> Path("test.py").absolute() # same as above undocumented
PosixPath('/home/name/test.py')
Why in Windows does this fail, but not Linux? Why is .absolute() undocumented?
I've looked around trying to figure out what the intended behavior is but there
is conflicting information.
Resolve seems to not work correctly on Windows. Bug?

These don't:
>>> print('{a: >10}'.format(a=type(a)))

[issue6690] BUILD_SET followed by COMPARE_OP (in) can be optimized if all items are consts
New submission from Alex :
Just like we turn BUILD_LIST; COMPARE_OP (in) into a LOAD_CONST if all
the members are consts, we can do the same for BUILD_SET, instead
turning it into a LOAD_CONST of a frozenset. The following is the
bytecode that is current produced for each datastructure.
>>> dis.dis(lambda o: o in (1,2,3))
1 0 LOAD_FAST0 (o)
3 LOAD_CONST 3 ((1, 2, 3))
6 COMPARE_OP 6 (in)
9 RETURN_VALUE
>>> dis.dis(lambda o: o in [1,2,3])
1 0 LOAD_FAST0 (o)
3 LOAD_CONST 3 ((1, 2, 3))
6 COMPARE_OP 6 (in)
9 RETURN_VALUE
>>> dis.dis(lambda o: o in {1,2,3})
1 0 LOAD_FAST0 (o)
3 LOAD_CONST 0 (1)
6 LOAD_CONST 1 (2)
9 LOAD_CONST 2 (3)
12 BUILD_SET3

[issue6922] Interpreter hangs up while trying to decode invalid utf32 stream.
New submission from Alex :
*** Prerequisites:
Python 2.6.2 (r262:71605, Apr 14 2009, 22:40:02) [MSC v.1500 32 bit
(Intel)] on win32
*** Description:
'utf_32_le' and 'utf_32_be' codecs are overconsuming memory when input
data are damaged and kwarg 'errors' to str.decode is other than 'strict'.
*** Steps:
1. Start interpreter
2. Type:
'\x01'.decode('utf_32_le', 'replace')
or
'\x01'.decode('utf32', 'ignore')
or
('something'.encode('utf32') + '\x00').decode('utf32', 'ignore')
3. Execute
*** Notes:
1. seems like any stream raising UnicodeDecodeError in 'strict' mode
causes hangup in 'ignore' or 'replace'.
*** Expected result:
1. AssertionError on "assert errors == 'strict'" raised, just as
bz2_codec does, if utf32 cannot be partially decoded at all.
2. Behaviour that 'utf8' and 'utf16' implement for such cases.
*** Received result:
1. Interpreter hangs, uses up to 100% of CPU kernel and starts to
consume RAM.
2. Grows large enough to consume all the RAM it could get (takes up to
several minutes on my machine).
3. Produces following traceback:
Traceback (most recent call last):
File "", line 1, in
File "C:\Python26\lib\encodings\utf_32_be.py", line 11, in decode
return codecs.utf_32_be_decode(input, errors, True)
MemoryError
4. Sometimes traceback is printed, but text "MemoryError" is not, just
leaving blank line in the place.
