I would definitely prefer to have bytes paths considered as 1st class

[issue40762] Writing bytes using CSV module results in b prefixed strings

[Sidhant Bansal]

Sidhant Bansal  added the comment:

The following code
```
import csv
with open("abc.csv", "w") as f:
   data = [b'\xc2a9', b'\xc2a9']
   w = csv.writer(f)
   w.writerow(data)
```
writes "b'\xc2a9',b'\xc2a9'" in "abc.csv", i.e the b-prefixed byte string 
instead of the actual bytes. 

Although one can argue that the write is done in text mode and not binary mode, 
however I believe the more natural expectation by the user will be to have the 
bytes written actually in the "abc.csv". Also take note that writing in binary 
mode is not supported by csv, so the only method to write bytes is this.

Can refer to this https://github.com/pandas-dev/pandas/issues/9712 to see one 
of the issues this brings in Pandas. From the discussion on this issue, the 
main reasons of changing this behaviour in Python would be to avoid leaking 
python's encoding system syntax into a generic data exchange format, i.e CSV.

[issue40761] unittest.TestCase.asserTrue return True even if the expr is False

[Steven D'Aprano]

Steven D'Aprano  added the comment:

Works for me in 3.7. See attached file. Can you provide a minimal piece of code 
that demonstrates the bug?

Since Python 3.5 is now only accepting security fixes, and numpy is a 
third-party library, unless you can demonstrate this in a more recent version I 
think we should close this as "Works For Me".

[issue40760] Dictionary comprehension using older division behavior

[Eric V. Smith]

Eric V. Smith  added the comment:

That's not what I see:

$ python3.8
Python 3.8.0b4 (default, Sep 15 2019, 15:56:44)
[GCC 7.4.0] on cygwin
Type "help", "copyright", "credits" or "license" for more information.
>>> some_dict = {3:4}
>>> {k: v/5 for k, v in some_dict.items()}
{3: 0.8}
>>>

Granted, this is a beta of 3.8 on cygwin, so maybe it's an outlier.

Can you show us a similar interactive session so we can see exactly what 
platform you're on, and what results you're seeing?

[issue40760] Dictionary comprehension using older division behavior

[Amol Sharma]

New submission from Amol Sharma :

Using comprehension to divide all the values in a dictionary like in the 
following results in integer division in 3.8.

some_dict = {k: v/5 for k, v in some_dict.items()}

This was solved by changing 5 to 5.0, reflecting behavior from python2. I would 
have expected to have the use the // operator for integer division.

Please correct me if this is expected behavior!

[issue40758] For 7.2.7. Code Examples, distinguish between the Tutorial and other documentation

[Chas Belov]

New submission from Chas Belov :

7.2.7. Code Examples https://devguide.python.org/documenting/#code-examples 
states:

Short code examples can be a useful adjunct to understanding. Readers can often 
grasp a simple example more quickly than they can digest a formal description 
in prose.

[snip]

The ellipsis for the sys.ps2 secondary interpreter prompt should only be used 
sparingly, where it is necessary to clearly differentiate between input lines 
and output lines. Besides contributing visual clutter, it makes it difficult 
for readers to cut-and-paste examples so they can experiment with variations.

-

I am requesting, as a newcomer to Python who is attempting to navigate the 
Tutorials and encountering challenges, that this be reworded to something like:

Short code examples can be a useful adjunct to understanding. Readers can often 
grasp a simple example more quickly than they can digest a formal description 
in prose.

[snip]

Outside of the Tutorial, the ellipsis for the sys.ps2 secondary interpreter 
prompt should only be used sparingly, where it is necessary to clearly 
differentiate between input lines and output lines. Besides contributing visual 
clutter, it makes it difficult for readers to cut-and-paste examples so they 
can experiment with variations.

Within the Tutorial, however, make the appearance of code blocks as consistent 
with what the student will be experiencing as feasible, to reduce cognitive 
load and allow them to focus on the content.

-

While I can in fact suss out whether a particular unmarked code block is meant 
to be input or output, it is a distraction that uses up some of my attention 
that I would prefer to spend on learning the language.

[issue40748] Tutorial 4.7 More on Defining Functions missing screen prompts

[Chas Belov]

Chas Belov  added the comment:

@Ama Aje My Fren, thank you for the advice re backporting.

As to your points on ..., both good points, and thank you for introducing me to 
the Documenting Python document, which I will review. While technically the 
Tutorial is indeed part of Python's documentation, I would argue that the 
Tutorial is not a place for shorthand. Learning a new language is hard enough 
without having to also struggle with inconsistencies in the tutorial interface.

My intent with this issue and my (upcoming) pull request is to make the 
mentioned code blocks consistent with the rest of the page and, indeed, with 
most of the rest of the tutorial. Most of the tutorial does show >>> and ... at 
the beginning of each line where the learner would see a prompt. If we are to 
avoid ... so that learners can copy and paste multiple lines, then why would we 
not do that through the entire tutorial?

I'm guessing your point is that we only need to show >>> and ... when there 
will be print output so that we need to distinguish between what is input and 
what is output. As someone who is currently learning Python, however, 
consistency in presentation is important to me and reduces cognitive load.

There are other places in the tutorial where code blocks were used for things 
which are not typed in, or are not typed without other text. Showing >>> and 
... for all verbatim input makes it unambiguous as to whether something is to 
be typed in.

I'll leave it to psychologists as to whether having to type or copy and paste 
one line at a time leads to better learning. 

By REPL, do you mean Read-Eval-Print Loop? I'm not familiar with the acronym 
and that's what Google is telling me it means. But a Read-Eval-Print Loop would 
have output, and my understanding is that you are arguing against use of ... 
when there is no output.

[issue40617] sqlite3: expose sqlite3_create_window_function

[Erlend Egeberg Aasland]

Erlend Egeberg Aasland  added the comment:

This is a good idea, but I think the Python interface should stay the same.

>From the user perspective, you'd only need to implement the 'value' and 
>'inverse' callbacks to transform your aggregate class into an aggregate window 
>class.

>From the CPython perspective, we'd only need to use 
>sqlite3_create_window_function() instead of sqlite3_create_function_v2(), if 
>we are compiling against SQLite 3.25.3 or newer.

I guess it would be nice to output a warning if the user aggregate class 
contains 'value' and 'inverse' callbacks, but sqlite3 _doesn't_ support 
aggregate window functions.

[issue40344] Programming FAQ about "What is the most efficient way to concatenate many strings together?" -- Improving the example

[Andy Lester]

Andy Lester  added the comment:

I'd also like to suggest that the question not be "most efficient" but 
"fastest".  I don't think it should treat "efficient" and "fast" as synonyms. 
"Efficient" can mean things other than execution speed, such as memory usage, 
or programmer time.  Are there space/time considerations besides execution 
time?  What if the user has a huge list and wants to use as little new 
allocated RAM as possible?

I understand that it's immediately after the "How do I speed up my program?" 
question, and I think it's worth considering making the question more explicit 
what kind of efficiency we're talking about.

[issue35883] Change invalid unicode characters to replacement characters in argv

[Johannes Berg]

Johannes Berg  added the comment:

I've also filed https://sourceware.org/bugzilla/show_bug.cgi?id=26034 for 
glibc, because that's where really the issues seems to be?

But perhaps python should be forgiving of glibc errors here.

[issue35883] Change invalid unicode characters to replacement characters in argv

[Johannes Berg]

Johannes Berg  added the comment:

Like I said above, it could be argued that the bug is in glibc, and then

https://p.sipsolutions.net/6a4e9fce82dbbfa0.txt

could be used as a simple LD_PRELOAD wrapper to work around this, just to 
illustrate the problem from that side.


Arguably, that makes glibc in violation of RFC 3629, since it says:


3.  UTF-8 definition

[...]

   In UTF-8, characters from the U+..U+10 range (the UTF-16
   accessible range) are encoded using sequences of 1 to 4 octets.

[...]

  (hexadecimal)|  (binary)
   +-
    - 007F | 0xxx
    0080- 07FF | 110x 10xx
    0800-  | 1110 10xx 10xx
   0001 -0010  | 0xxx 10xx 10xx 10xx

[...]

   Implementations of the decoding algorithm above MUST protect against
   decoding invalid sequences.

[...]

Here's a simple test program:

[issue40757] tarfile: ignore_zeros = True won't raise exception even on invalid (non-zero) TARs

[mxmlnkn]

New submission from mxmlnkn :

Normally, when opening an existing non-TAR file, e.g., a file with random data, 
an exception is raised:

tarfile.open( "foo.txt" )

---
ReadError Traceback (most recent call last)
 in ()
> 1 f = tarfile.open( "notes.txt", ignore_zeros = False )

/usr/lib/python3.7/tarfile.py in open(cls, name, mode, fileobj, bufsize, 
**kwargs)
   1576 fileobj.seek(saved_pos)
   1577 continue
-> 1578 raise ReadError("file could not be opened successfully")
   1579 
   1580 elif ":" in mode:

ReadError: file could not be opened successfully

However, when specifying ignore_zeros = True, this check against invalid data 
seems to be turned off. Note that it is >invalid< data not >zero< data and 
therefore should still raise an exception!

tarfile.open( "foo.txt", ignore_zeros = True )

Iterating over that opened tarfile also works without exception however nothing 
will be iterated over, i.e., it behaves like an empty TAR instead of like an 
invalid TAR.

[issue40756] Second argument of LoggerAdapter.__init__ should default to None

[Arturo Escaip]

New submission from Arturo Escaip :

The 'extra' argument is not always used by custom logger adapters. There
example:

class IndentAdapter(logging.LoggerAdapter):
def process(self, msg, kwargs):
indent = kwargs.pop(indent, 1)
return ' ' * indent + msg, kwargs

It is cleaner and friendlier to default the 'extra' argument to None
instead of either forcing the subclasses of LoggerAdapter to pass a None
value directly or to override the constructor.

[issue35883] Change invalid unicode characters to replacement characters in argv

[Johannes Berg]

Johannes Berg  added the comment:

And wrt. _Py_DecodeUTF8Ex() - it doesn't seem to help. But that's probably 
because I'm not __ANDROID__, nor __APPLE__, and then regardless of 
current_locale being non-zero or not, we end up in decode_current_locale() 
where the impedance mismatch happens.

Setting PYTHONUTF8=1 in the environment works too, in that case we do get into 
_Py_DecodeUTF8Ex().

[issue35883] Change invalid unicode characters to replacement characters in argv

[Johannes Berg]

Johannes Berg  added the comment:

In fact that python one-liner works with just about everything else that you 
can throw at it, just not something that "looks like utf-8 but isn't".

And of course adding LC_CTYPE=ascii or something like that fixes it, as you'd 
expect. Then the "surrogateescape" works fine, since mbstowcs() won't try to 
decode it as utf-8.

[issue35883] Change invalid unicode characters to replacement characters in argv

[Johannes Berg]

Johannes Berg  added the comment:

A simple test case is something like

  ./python -c 'import sys; 
print(sys.argv[1].encode(sys.getfilesystemencoding(), "surrogateescape"))' 
"$(echo -ne '\xfa\xbd\x83\x96\x80')"


Which you'd probably expect to print

  b'\xfa\xbd\x83\x96\x80'

i.e. the same bytes that were passed in, but currently that fails.

[issue35883] Change invalid unicode characters to replacement characters in argv

[Johannes Berg]

Johannes Berg  added the comment:

Pretty sure this is an issue still, I see it on current git master.

This seems to work around it?

https://p.sipsolutions.net/603927f1537226b3.txt

Basically, it seems that mbstowcs() and mbrtowc() on glibc with utf-8 just 
blindly decode even invalid UTF-8 to a too large wchar_t, rather than failing.

[issue21724] resetwarnings doesn't reset warnings registry

[Julian Berman]

Julian Berman  added the comment:

Just ran into this myself -- not sure what the intended fix is (hopefully it's 
"add a function that restores the warnings configuration to its defaults?" 
Changing resetwarnings seems likely to be not doable I assume.)

But in the meanwhile, is a doc patch acceptable? The current documentation for 
resetwarnings is really deceptive, and makes it look like it does what @pitrou 
(and I) thought it did:

> Reset the warnings filter. This discards the effect of all previous calls to 
> filterwarnings(), including that of the -W command line options and calls to 
> simplefilter().

Compare to the docstring of the function (and to what it actually does):

> """Clear the list of warning filters, so that no filters are active."""

But there are still too many implementation details of the warnings module 
leaking through here -- for end users it's just "restore the warnings 
configuration to its defaults" (what it looks like resetwarnings should do) or 
"unfilter all warnings, even beyond the filters configured by default" (what it 
actually does).

Is at least making the docs reflect the latter a reasonable patch to submit, to 
start, while what to do about the former is thought about?

I found this tip about uncleaned files after executing "make clean" 
(https://bugs.python.org/msg346553). So, I decided to wipe out all python3.7 
files from my computer and repeat the installation process. It worked!!
Anyway, thank you again for your response and your tip. It really made my day

[issue40283] Documentation of turtle.circle()

[Florian Dahlitz]

Florian Dahlitz  added the comment:

I tested it and can confirm the findings from @cajetan.rodrigues. However, this 
does not seem to be _not_ documented. The documentation clearly states that 
using a positive value for radius results in a counter-clockwise direction, 
whereas a negative number results in a clockwise direction. This is true.

Now, let's have a look at using radius _together_ with extent, which is not 
(clearly) documented as this point. Using a positive value results in the same 
direction, but in a not full drawn circle. This seems intuitive and is 
documented:

If extent is not given, draw the entire circle.
If extent is not a full circle, one endpoint of the arc is the current pen 
position.

Using a negative value changes the direction of radius, which does also seem 
reasonable and intuitive.

My suggestion is not to replace "radius" by "extent" as suggested by @guchao as 
it is IMHO wrong. But I agree that it would be good to leave a note there or to 
add examples demonstrating the behaviour of different (signed) values of radius 
and extent, so the intent and behaviour is clearly documented.

Are those sections really to be entered in the REPL or could they be
seen as independent code blocks in a file e.g.?

None of those sections has output ... so maybe not put the ellipsis?

[issue40028] Math module method to find prime factors for non-negative int n

[Mark Dickinson]

Mark Dickinson  added the comment:

[Rémi Lapeyre]

> In the end, if some core devs think that putting together the various 
> discussions for an imath module in a coherent PEP [...]

I can't answer for other core devs. My *guess* is that there's a reasonable 
chance that a well-written PEP for this would be accepted, but that's just a 
guess.

For myself, I'm not opposed to the addition, but neither am I yet convinced 
it's a good idea; call me +0. The number of bad prime-checking and 
factorisation algorithms that turn up on Stack Overflow (and not just in the 
questions, either) is enough to convince me that it's worth having _something_ 
basic and non-terrible for people to use.

I *am* strongly opposed to adding an imath module without first having a PEP - 
many aspects are unclear and in need of wider discussion. I unfortunately don't 
personally have sufficient time and energy available to push a PEP discussion 
through myself.

If you want to take this further, restarting a discussion on the python-ideas 
mailing list may be the way to go. It may still be worth drafting a PEP first, 
though: a draft PEP would likely help guide that discussion, and perhaps avoid 
it going totally off-topic.

Unless there is an issue, automatic back-porting should handle it.
PR against master(dev/3.10) should be enough.

[issue40056] more user-friendly turtledemo

[Terry J. Reedy]

Terry J. Reedy  added the comment:

I will look at the two changes separately.  Spaces could be backported, but 
since they are not really typos, there is no real need to.  I will compare td 
for master and 3.9 to compare appearance.

[issue40160] documentation example of os.walk should be less destructive

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

1. There is already a warning before example.
2. Even if you blindly copy-paste the example it will not work. You have to set 
the top variable.

So I don't see any problem here. You always can shoot yourself in the foot if 
try enough.

[issue40753] Remove Python 2 compatibility code from pathlib

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

Similar cleanup (and many many others) was proposed when pathlib was initially 
added to the stdlib. They were rejected, so now we need a new discussion to 
revise the old decision. See issue20002.

[issue40752] Implement PurePath.__len__

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

Path is not a string with bells and whistles. It was intentionally made not a 
string subclass because some string operations (including len()) just do not 
make sense for path or are ambiguous.

I am closing this as it goes against the initial design of pathlib. If you 
disagree, discuss this idea on Python-ideas first and get the support of other 
core developers.
