[issue42359] tutorial: list is a class

[Raymond Hettinger]

Raymond Hettinger  added the comment:

I think the current wording is fine.  After the type/class unification we tend 
to use the words "type" and "class" almost interchangeably.  For builtins, we 
still tend to say type though.

The language itself tends to mix the terms as well:

>>> class A:
   pass

>>> type(A)

>>> type(list)

[issue42359] tutorial: list is a class

[Andy Harrington]

New submission from Andy Harrington :

Documentation in Tutorial section 9.3.3 seems to be stuck in Python 2:

"In Python, the term method is not unique to class instances: other object 
types can have methods as well. For example, list objects have methods called 
append, insert, remove, sort, and so on."

In Python 3 built-in types are derived from Object, so list is now a class, 
right?

[issue42353] Proposal: re.prefixmatch method (alias for re.match)

[Matthew Suozzo]

Matthew Suozzo  added the comment:

> It just won't work unless you add explicit ".*" or ".*?" at the start of the 
> pattern

But think of when regexes are used for validating input. Getting it to "just 
work" may be over-permissive validation that only actually checks the beginning 
of the input. They're one missed test case away from a crash or, worse, a 
security issue.

This proposed name change would help make the function behavior obvious at the 
callsite. In the validator example, calling "prefixmatch" would stand out as 
wrong to even the most oblivious, documentation-averse user.

> My point is that re.match is a common bug when people really want re.search.

While I think better distinguishing the interfaces is a nice-to-have for 
usability, I think it has more absolute benefit to correctness. Again, 
confusion around the semantics of "match" were the motivation for adding 
"fullmatch" in the first place but that change only went so far to address the 
problem: It's still too easy to misuse the existing "match" interface and it's 
not realistic to remove it from the language. A new name would eliminate this 
class of error at a very low cost.

[issue42328] ttk style.map function incorrectly handles the default state for element options.

[Pat Thoyts]

Pat Thoyts  added the comment:

So if you look at the clamTheme.tcl file you can see the definition of the map 
for the TNotebook.Tab style looks like the following:

ttk::style map TNotebook.Tab \
  -padding [list selected {6 4 6 2}] \
  -background [list selected $colors(-frame) {} $colors(-darker)] \
  -lightcolor [list selected $colors(-lighter) {} $colors(-dark)] \
  ;

The vista theme uses these too on Windows.

So calling this from script we can see the resulting empty elements in tcl:

% ttk::style map TNotebook.Tab
-lightcolor {selected #eeebe7 {} #cfcdc8} -padding {selected {6 4 6 2}} 
-background {selected #dcdad5 {} #bab5ab}

As I put in the bug, this gets mistranslated in python with the value for that 
state map element getting put into the first element.

The simplest demonstration is that the following raises an exception:

import tkinter as tk
import tkinter.ttk as ttk
style = ttk.Style()
style.theme_use('clam')
style.map('Custom.TNotebook.Tab', **style.map('TNotebook.Tab'))

We don't fancy this kind of passive-aggressive and accusatory communication 
style. Instead we prefer constructive collaboration without personal attacks.

For your information our buildbot infrastructure perform regular testing on a 
lot of hardware platforms, distributions, and compilers including PPC64 and 
s390x big endian machines.

Please attach your config.log and provide more information about your platform, 
compiler, and hardware.

[issue42339] official embedded Python fails to import certain modules

I agree that in general mixed-language can be odd. But I guess you could also 
argue it's useful that Python doesn't add another layer of complexity, and 
simply uses the system's own FormatMessage() function, also because developers 
are already used to seeing such messages in other applications as well. Just 
playing devil's advocate here.

At the same time, I feel it would be helpful to users if there would, in this 
specific case, be a more helpful message as well (alongside the same error that 
is already shown), something that points more directly in the direction of the 
solution.

[issue42339] official embedded Python fails to import certain modules

[Eryk Sun]

Eryk Sun  added the comment:

> want to add KB3063858?

The documentation of the embeddable package [1] could highlight the need for 
KB2533623. Currently it's directly mentioned only in "What's New in Python 3.8" 
[2].

> ImportError: DLL load failed while importing _lzma: 
> De parameter is onjuist.

Mixed-language output is awkward. A common _Py_FormatMessage function could be 
added in 3.10 that tries getting an error message in English before trying to 
get it in the user's default language.

[issue42358] Python 3.9.0 unable to detect ax_cv_c_float_words_bigendian value on nigendan system

[Dennis Clarke]

New submission from Dennis Clarke :

Seems related to issue42173 where the idea on the table was, simply to
drop Solaris support and to quote Mr Stinner to "let the code slowly
die".  Regardless of this sort of neglect there are people who do try
to use Python on big endian risc systems such as Solaris or Debian Linux
in fact. Wherein a trivial configure reveals :

configure: error: 

Unknown float word ordering. You need to manually preset
ax_cv_c_float_words_bigendian=no (or yes) according to your system.

So it seems that the m4/ax_c_float_words_bigendian.m4 needs to be
manually hacked or the configure script itself is at fault. 

I will give this a try on big endian IBM Power and also IBM Power9
ppc64le as well as FreeBSD running in RISC-V rv64imafdc little endian
and see what happens. I suspect that the little endian systems will
be no great concern as the bulk of Python devs seem to have never
seen anything else other than little endian systems running Red Hat.

To hack around this floating point endian test with blunt force :

This is a hack of course and it gets past the endian test sickness. 

Shortly thereafter the compile fails due to a trivial C99 code

[issue42330] Add browsh in the webbrowser module

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

I concur with Terry.

Actually, registering the browser is not necessary for using it. Set the 
environment variable BROWSER and use your favorite browser. The following 
example uses curl (which is not registered as in the webbrowser module) as a 
browser:

BROWSER=curl python3 -m webbrowser -n http://example.org

The registry in the webbrowser module is used for the case if you use Python on 
some non-mainstream platform which does not have OS-level infrastructure for 
running default browser or settings are empty. I.e. it is not Windows or macOS 
and does not support OpenDesktop and Posix specifications, and BROWSER is not 
set. If you have such marginal system and use marginal browser on it, it is 
worth to spend some time for setting BROWSER or configuring www-browser, 
x-www-browser, xdg-open, etc.

[issue42353] Proposal: re.prefixmatch method (alias for re.match)

[Gregory P. Smith]

Gregory P. Smith  added the comment:

My point is that re.match is a common bug when people really want re.search.

re.prefixmatch makes it explicit and non-confusing and thus unlikely to be used 
wrong or misunderstood when read or reviewed.

The term "match" when talking about regular expressions is not normally meant 
to imply any anchoring as anchors can be expressed within the regex.  Python is 
relatively unique in bothering to have different methods for a prefix match and 
an anywhere match.  (We'd have been better off without a match method entirely, 
only having search - too late now)

Hitansh K Doshi  added the comment:

I contacted them I got to know that the project is discontinued since 2008 and 
the resources are no more maintained.
they have provided with an github repo and an archive file link 

This is the exact reply:
Unfortunately, both UW IMAP and Pine/Alpine development was discontinued back 
in 2008 and removed from University systems in 2018. A community copy still 
exists at https://github.com/uw-imap/imap but UW provides no support or 
resources for it anymore.  It looks like some of the information may still be 
available via the Wayback Machine 
https://web.archive.org/web/20080323102305/https://www.washington.edu/imap/  

Mark Crispin, the lead developer at UW, started a fork of it called Panda IMAP 
when he was laid off in 2008, but he has unfortunately passed away and that no 
longer seems to be maintained.

what would you like me to do next ?

[issue42356] Dict inline manipulations

[Eric V. Smith]

Eric V. Smith  added the comment:

I think you should bring this up on the python-ideas mailing list if you'd like 
to see it discussed. It will likely also require a PEP, similar to PEP 584.

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

I seen a code which uses re.search() with anchor ^ instead of re.match(), but I 
never seen a code which uses re.match() instead of re.search(). It just won't 
work unless you add explicit ".*" or ".*?" at the start of the pattern, and it 
is a clear indication that re.match() matches the start of the string.

[issue42339] official embedded Python fails to import certain modules

[Jelle Geerts]

Jelle Geerts  added the comment:

Problem still occurs with newer KB3118401 installed (instead of KB2999226).

But good news:

Installing update KB3063858 (or the older KB2533623) resolves the issue.

That update adds the new kernel32.dll functions SetDefaultDllDirectories, 
AddDllDirectory, and RemoveDllDirectory.

That explains why the issue didn't occur with (embedded) Python 3.7, since 
Python started using those functions since 3.8 if I recall correctly.

So, this issue can be considered solved. But...

Thinking along here, maybe there's a list of updates (or FAQ) to which you want 
to add KB3063858?

(Note of course it only affects Windows 7 users that use the embedded Python 
3.8, and it doesn't affect 3.7 users and 3.9 doesn't support Windows 7.)

Or, maybe even add a bit of logic that detects when Python fails to load one of 
the _.pyd PE images (like _socket.pyd) and show a simple warning that tells 
users to check said FAQ? Or maybe that's asking too much.

Just some thoughts.

[issue42356] Dict inline manipulations

[Tomek H]

New submission from Tomek H :

With Python3.9 there is a great feature for merging `dict`s:
{1: 'a'} | {2: 'b'} => {1: 'a', 2: 'b'}


It would be very handy to filter out a dict with a similar fashion (for example 
& operator with a list/tuple/frozenset of keys you want to get back):
{1: 'a', 2: 'b', 3: 'c'} & [1, 3, 4] == {1: 'a', 3: 'c'}
{1: 'a', 2: 'b', 3: 'c'} & {1, 3, 4} == {1: 'a', 3: 'c'}


Also, omitting specified keys (for example - operator with a 
list/tuple/frozenset of keys you want to suppress):
{1: 'a', 2: 'b', 3: 'c'} - [3, 4] == {1: 'a', 2: 'b'}
{1: 'a', 2: 'b', 3: 'c'} - {3, 4} == {1: 'a', 2: 'b'}


Regards!

[issue42316] Walrus Operator in list index

[Terry J. Reedy]

Terry J. Reedy  added the comment:

PEP 572 does not saw much of anything about when parens are needed.  Nor does 
the low priority itself.  Looking through the grammar of expressions, an 
assignment_expression is also a starred_expression, a positional_item (in 
calls), and the first part of a comprehension. It is not itself an plain 
expression unless and until wrapped in parentheses.  Subscription requires an 
expression list, which may be a single expression.

To put it another way: an expression is an assignment expression but an 
assignment expression with a "name :=" prefix is not an expression, so parens 
are required anywhere an expression is required.  That includes subscripts, 
slicings, displays, call items other than positional items, comprehension parts 
other than the initial expression (maybe, check), parts of conditional 
expressions (maybe, check), and lambda expression bodies.  After checking, I 
would like a sentence added to the doc before the 'go see the PEP' bit.

This has nothing to do with asyncio.

You have 2 user names, both nosy.  You logged in with the lower-case name, 
hence the Author listing above.  However, your CLA was registered with your 
uppercase (older?) login name.  (If this is not what you intended, please write 
ewa at ython.org and explain.) Hence your name (login name) is not followed by 
the CLA * marker.  This was a bit confusing until I decyphered the situaiton.

[issue42330] Add browsh in the webbrowser module

[Terry J. Reedy]

Terry J. Reedy  added the comment:

We do not add just any old or new browser to webrowser's predefined list.  (And 
there are likely some that should be dropped.)  The last addition was the 
Chrome group in 3.3.  Neither Microsoft Explorer or Edge are listed.  I believe 
the former was considered to be covered sufficient well by 'windows-default'.

On Windows and Mac, one can use any browser by making it the default.  It is 
also possible for any browser to make itself easily usable from Python by 
adding a module that registers the browser controller class on import.  You 
should suggest this to the browsh dev and see if *they* care.

Looking further, there are about 10 browsers with measured usage listed in 
https://en.wikipedia.org/wiki/Web_browser that are not on the webbrowser list.  
There are more at https://en.wikipedia.org/wiki/List_of_web_browsers, including 
 Browsh appears on neither list.  It does appear on 
https://en.wikipedia.org/wiki/Text-based_web_browser.  But it seems too obscure 
to deserve being added.  So I think this request should be rejected.

[issue42334] Subclassing int and complex with keyword arguments weird

[Terry J. Reedy]

Terry J. Reedy  added the comment:

When reporting a failure please copy and paste the exception and message and 
when non-trivial, the traceback.   In this case:  "TypeError: 'test' is an 
invalid keyword argument for complex()".  The difference between int and 
complex versus float is that the former have keyword arguments, so they check 
for invalid keyword arguments, whereas float take no keyword arguments, so it 
does not check for validity and, for subclasses, passes them on.

The example code does not error on the latest 3.10. I'm guessing that the

[issue42335] Python Crashes Exception code 0xc0000374 ntdll.dll

[Terry J. Reedy]

Terry J. Reedy  added the comment:

When python as delivered crashes running pure non-ctype Python code, we usually 
consider it a bug to be fixed.  As soon as one pokes around with ctypes or 
imports 3rd party binaries, the crash is usually due to a user or 3rd par.  So 
this probably should be closed as 'not a (cpython) bug' or '3rd party', at 
least until the crash can be duplicated run pure python.  I am leaving it open 
for now in case someone checks the zip.

You might get more help posting on python-list with an import list or zip 
requirements.txt.  Some other user might know something about intermittent 
crashes in one of the packages.
