Re: Invalid literal for int() with base 10?
Ok, I'm not finding any info. on the int() for converting a str to an int (that
specifies a base parameter)?! The picture is of the code I've written... And
the base 10 paradigm involved?? years = int('y') # store for calculation
ValueError: invalid literal for int() with base 10: 'y'
What is meant by "invalid literal"? I'm trying to convert str to int, and I
didn't know I needed to specify the base. Plus I haven't read anything that I
need to specify the base for the int().
Attached is the code, showing the code and the execution of said code.

From geeksforgeeks.org, on converting the string created by the input() to an INT
We can first convert the string representation of float into float using
float() function and then convert it into an integer using int().So, why can't
a string of an integer be converted to an integer, via
print(int(str('23.5')))???

Kevin Hock added the comment: > Maybe instead a note could be put in the Pathlib doc noting functions that > accept path arguments might not accept Path objects? My concern with that is that someone using `pkgutil` wouldn't see it. However, I can see the argument that fixing the 'source' is better than each use. I'm not sure how wide-spread these kind of issues are to weigh in on how many 'uses' there are. If that makes sense. >Should pkgutil call os.fspath() in this case? I really like that idea.

New submission from Kevin Kirsche : When using importlib.metadata.version with tools such as poetry which may install the current package one or more times, importlib.metadata.version is not deterministic in returning the latest version of the package, instead returning the first one located. As it's unclear if this behavior is desired by importlib, I'm creating this issue to determine if this is intentional behavior or a bug. I have opened the following poetry issue: * https://github.com/python-poetry/poetry/issues/5204 I have also created the following reproduction repository for the installation issue: https://github.com/kkirsche/poetry-remove-untracked When the after is modified to return the version, it returns the first one found (e.g. if you go 3.0.0 -> 3.0.1 -> 3.0.2, each would be installed and the library would return 3.0.0 to the caller) Thank you for your time and consideration. I apologize if this is not something that requires action by the Python team.

[issue46722] Different behavior for functiools.partial between inspect.isfunction() and other inspect.is*function()
Kevin Shweh added the comment: Frankly, it doesn't make sense that isgeneratorfunction or iscoroutinefunction unwrap partials at all. The original justification for making them do that back in https://bugs.python.org/issue34890 was invalid - the original argument was that isfunction unwraps partials, but it doesn't, and I don't think it ever did. isfunction is supposed to be a very specific check for Python function objects. It rejects all sorts of other callables, like sum (a built-in function), super (a type), or method objects (which wrap functions in a very similar way to partial). Having it be a check for *either* a Python function object *or* a partial object wrapping a Python function object seems to just make it less useful. -- nosy: +Kevin Shweh ___ Python tracker <https://bugs.python.org/issue46722> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

The fix for that issue caused this issue, which happens if the thread gets interrupted *during* the acquire, in which case it *does* release the lock (that someone else is holding) and *does* perform end-of-thread cleanup even though it's not supposed to do either of those things. -- ___ Python tracker <https://bugs.python.org/issue46726> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue46726] Thread spuriously marked dead after interrupting a join call
New submission from Kevin Shweh :
This code in Thread._wait_for_tstate_lock:
try:
if lock.acquire(block, timeout):
lock.release()
self._stop()
except:
if lock.locked():
# bpo-45274: lock.acquire() acquired the lock, but the function
# was interrupted with an exception before reaching the
# lock.release(). It can happen if a signal handler raises an
# exception, like CTRL+C which raises KeyboardInterrupt.
lock.release()
self._stop()
raise
has a bug. The "if lock.locked()" check doesn't check whether this code managed
to acquire the lock. It checks if *anyone at all* is holding the lock. The lock
is almost always locked, so this code will perform a spurious call to
self._stop() if it gets interrupted while trying to acquire the lock.
Thread.join uses this method to wait for a thread to finish, so a thread will
spuriously be marked dead if you interrupt a join call with Ctrl-C while it's
trying to acquire the lock. Here's a reproducer:
import time
import threading
event = threading.Event()
def target():
event.wait()
print('thread done')
t = threading.Thread(target=target)
t.start()
print('joining now')
try:
t.join()
except KeyboardInterrupt:
pass
print(t.is_alive())
event.set()
Interrupt this code with Ctrl-C during the join(), and print(t.is_alive()) will
print False.

[issue45756] mock raises exception when using a spec with an attribute that raises exception on access
New submission from Kevin Jamieson :
In Python 3.8 and later creating a mock with a spec specifying an object
containing a property that happens to raise an exception when accessed will
fail, because _mock_add_spec calls getattr() on every attribute of the spec.
This did not happen in Python 3.6/3.7.
This is likely a fairly unusual scenario (and in the particular case where I
encountered this I could just use a class instead of an instance for the spec),
but it was surprising.
For example:
# cat test.py
from unittest import mock
class Foo:
@property
def bar(self) -> str:
raise Exception('xxx')
m = mock.MagicMock(spec=Foo())
# python3.11 test.py
Traceback (most recent call last):
File "/root/test.py", line 8, in
m = mock.MagicMock(spec=Foo())

[issue45755] Mock spec with a specialized generic class does not mock class attributes
New submission from Kevin Jamieson :
This worked in Python 3.6, but in Python 3.7 and later creating a mock with a
spec specifying a subscripted generic class does not mock any of the attributes
of the class, because those attributes are not returned by dir().
For example:
# cat test.py

from unittest import mock
T = TypeVar('T')
class Foo(Generic[T]):
def bar(self) -> None:
pass
m = mock.MagicMock(spec=Foo[int])

[issue45104] Error in __new__ docs
New submission from Kevin Shweh : The data model docs for __new__ say "If __new__() is invoked during object construction and it returns an instance or subclass of cls, then the new instance’s __init__() method will be invoked..." "instance or subclass of cls" is incorrect - if for some reason __new__ returns a subclass of cls, __init__ will not be invoked, unless the subclass also happens to be an instance of cls (which can happen with metaclasses). This should probably say something like "instance of cls (including subclass instances)", or "instance of cls or of a subclass of cls", or just "instance of cls". -- assignee: docs@python components: Documentation messages: 401065 nosy: Kevin Shweh, docs@python priority: normal severity: normal status: open title: Error in __new__ docs versions: Python 3.10, Python 3.11, Python 3.8, Python 3.9 ___ Python tracker <https://bugs.python.org/issue45104> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue45054] json module should issue warning about duplicate keys
Kevin Mills added the comment:
Sorry to the people I'm pinging, but I just noticed the initial dictionary in
my example code is wrong. I figured I should fix it before anybody tested it
and got confused about it not matching up with my description of the results.
It should've been:
import json
d1 = {"1": "fromstring", 1: "fromnumber"}
string = json.dumps(d1)
print(string)
d2 = json.loads(string)
print(d2)

[issue45054] json module should issue warning about duplicate keys
New submission from Kevin Mills :
The json module will allow the following without complaint:
import json
d1 = {1: "fromstring", "1": "fromnumber"}
string = json.dumps(d1)
print(string)
d2 = json.loads(string)
print(d2)
And it prints:
{"1": "fromstring", "1": "fromnumber"}
{'1': 'fromnumber'}
This would be extremely confusing to anyone who doesn't already know that JSON
keys have to be strings. Not only does `d1 != d2` (which the documentation does
mention as a possibility after a round trip through JSON), but `len(d1) !=
len(d2)` and `d1['1'] != d2['1']`, even though '1' is in both.
I suggest that if json.dump or json.dumps notices that it is producing a JSON
document with duplicate keys, it should issue a warning. Similarly, if
json.load or json.loads notices that it is reading a JSON document with
duplicate keys, it should also issue a warning.

[issue44921] dict subclassing is slow
Kevin Shweh added the comment: Of course it's reasonable to support dict subclasses. We already have a bunch of dict subclasses in the standard library, like collections.defaultdict and collections.Counter, and collections.Counter is significantly slower than it could be because of this issue. (collections.defaultdict seems to be unaffected due to differences between classes implemented in C and Python.) dict.__getitem__ even has dedicated support for a __missing__ hook, which is only useful for subclasses. -- nosy: +Kevin Shweh ___ Python tracker <https://bugs.python.org/issue44921> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue43784] [Windows] interpreter hangs indefinitely on subprocess.communicate during __del__ at script exit
New submission from Kevin M :
I've noticed an issue (or user error) in which Python a call that otherwise
usually works in the __del__ step of a class will freeze when the Python
interpreter is exiting.
I've attached sample code that I've ran against Python 3.9.1 on Windows 10.
The code below runs a process and communicates via the pipe.
class SubprocTest(object):
def run(self):
print("run")
proc_args = ["cmd.exe"]
self._process = subprocess.Popen(proc_args,
stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
def __del__(self):
print("__del__")
if self._process is not None:
self.terminate()
def terminate(self):
print("terminate")
self._process.communicate(input=b"exit\n", timeout=1)
print("kill")
self._process.kill()
self._process = None
if __name__ == "__main__":
s = SubprocTest()
s.run()
del s
print("s done")
t = SubprocTest()
t.run()
print("t done")
Current output:
run
__del__
terminate
kill
s done
run
t done
__del__
terminate
<<<<<< hangs indefinitely here, even though timeout=1
Expected output:
run
__del__
terminate
kill
s done
run
t done
__del__
terminate
kill
In normal circumstances, when you del the object and force a run of __del__(),
the process ends properly and the terminate() method completes.
When the Python interpreter exits, Python calls the __del__() method of the
class. In this case, the terminate() never completes and the script freezes
indefinitely on the communicate()

[issue43344] RotatingFileHandler breaks file type associations
New submission from Kevin Hollingshead : The filenames generated by logging.RotatingFileHandler breaks the ability to associate a program (e.g. notepad++, sublime text, etc.) with the log files using Windows or OSX file associations because the extension is overridden by the added suffix. For example, if I specify the filename as "test.log" for a TimeBasedRotatingFileHandler with a suffix of "%Y%m%d", rolled over files are named test.log.MMDD. There is no way to associate a program with this type of file extension. A good non-breaking fix would be to add a parameter "extension" to RotatingFileHandler, and if specified would be applied to all filenames. Thus if I specify filename="test" and "extension="log" for my handler it would give "test.log" for the initial file and "test.MMDD.log" for rollover files. -- components: Extension Modules files: logger_bug.py messages: 387793 nosy: kh14821 priority: normal severity: normal status: open title: RotatingFileHandler breaks file type associations type: behavior Added file: https://bugs.python.org/file49840/logger_bug.py ___ Python tracker <https://bugs.python.org/issue43344> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue38946] IDLE on macOS 10.15 Catalina does not open double-clicked files if app already launched
Kevin Purrone added the comment: I have little experience posting in forums, so if this post is in the wrong place, please let me know. I am running Python3.9, with Apple OS 10.15.7 I was using IDLE successfully for a class in Python for the past three weeks, although I was rarely able to open a file by double clicking it. It actually worked a few times, but most of the time, nothing happened, and I would open IDLE first, and then open a file from its file menu. But today, IDLE will not open. When I click on the icon in the dock like I usually did, it seems to open for about .5 seconds, and then quits. Also, now when I double click on a .py file, IDLE will open for about .5 seconds and then quits. I reinstalled the package, but no change. However, in terminal I can launch python with this command: python3.9. Then I can launch IDLE with this command: import idlelib.idle. The IDLE window opens, and I can open files from the file menu and they run as before. However, the title of the file menu is now "Python" where before, it was "IDLE" -- nosy: +KevinPurrone versions: +Python 3.9 -Python 3.8 ___ Python tracker <https://bugs.python.org/issue38946> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue43122] Python Launcher doesn't open a terminal window
New submission from Kevin : Machine: new MacBook Air with M1 chip, running Big Sur Downloaded: Python versions 2.7, 3.8, and 3.9 Situation: Programs run just fine IF I run them out of a terminal window (/usr/local/bin/python name-of-python-program). Also programs that use Tkinter windows and don't require a terminal window for input or output run properly. Problem: Can't launch programs by double-clicking on them. When I try, Python Launcher starts and displays its preferences and there is a microsecond flash of something on the screen that appears to descend into the program icon that was clicked on. Note: Playing with a shebang in the program made no difference. Everything works fine when the programs are opened and run in IDLE. -- messages: 386473 nosy: kjw priority: normal severity: normal status: open title: Python Launcher doesn't open a terminal window type: behavior versions: Python 3.8 ___ Python tracker <https://bugs.python.org/issue43122> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
For example: Question, moving a folder (T061RR7N1) containing a Specific file (ReadCMI), to folder: C:\\...\DUT0
for path, dir, files in os.walk(myDestinationFolder):
# for path, dir, files in os.walk(destfolder):
print('The path is %s: ', path)
print(files)
os.chdir(mySourceFolder)
if not os.path.isfile(myDestinationFolder + file):
# if not os.path.isfile(destfolder + file):
print('The file is %s: ', file)
shutil.copytree(mySourceFolder, myDestinationFolder)
# os.rename(path + '\\' + file, myDestinationFolder + file)
# os.rename(path + '\\' + file, destfolder + file)
os.rename(path + '\\' + file, myDestinationFolder + file)
elif os.path.isfile(myDestinationFolder + file):
# os.rename(path + '\\' + file, destfolder + file)
shutil.copytree(mySourceFolder, myDestinationFolder)
So I would very much appreciate your ideas on the above statements!Because...I
think I've got the wrong function (os.path.isfile), when I should be (s/b)
using a stepped approach!Note: program allows input of ID = T061RR7N1 (for
example)1) find the folder containing "file": where folder = T061RR7N1, and
file is "ReadCMI"; if TRUE, shutil.copytree C:\\...\T061RR7N1\ReadCMI (TO)
C:\\...\DUT[?], where [?] is a num from 0 - 15.2) append to
C:\\...\DUT[?]\T061RR7N1, which contains "ReadCMI"!
and would you mind telling me why this works (in every example I've found on
the internet): r'C:\\anyfolder\\anyotherfolder\\'...what does the "r" signify?
If it's 'read', why can't I use the 'a' for append?

[issue42915] enum.Flag ~ bitwise negation is very slow and can't be defined as a Flag value
New submission from Kevin Chen :
Here's a code sample:
```
import time
from enum import Flag, auto
class MyFlag(Flag):
NONE = 0
FLAG_1 = auto()
FLAG_2 = auto()
FLAG_3 = auto()
FLAG_4 = auto()
FLAG_5 = auto()
FLAG_6 = auto()
#
# NOT_FLAG_1_OR_2 = ~FLAG_1 & ~FLAG_2
def test_flag():
f = MyFlag.NONE
inverted = (
~MyFlag.FLAG_1
& ~MyFlag.FLAG_2
& ~MyFlag.FLAG_3
& ~MyFlag.FLAG_4
& ~MyFlag.FLAG_5
& ~MyFlag.FLAG_6
)
return f & inverted
INVERTED = (
~MyFlag.FLAG_1
& ~MyFlag.FLAG_2
& ~MyFlag.FLAG_3
& ~MyFlag.FLAG_4
& ~MyFlag.FLAG_5
& ~MyFlag.FLAG_6
)
def test_flag_cached():
f = MyFlag.NONE
return f & INVERTED
if __name__ == "__main__":
start_time = time.time()
for _ in range(10_000):
test_flag()
elapsed = time.time() - start_time
print(f"Took normal {elapsed:2f} seconds.")
start_time = time.time()
for _ in range(10_000):
test_flag_cached()
elapsed = time.time() - start_time
print(f"Took cached {elapsed:2f} seconds.")
```
And its outputs:
```
Took normal 1.799731 seconds.
Took cached 0.009488 seconds.
```
Basically, bitwise negation is very very slow. From what I can tell, it seems
that a lot of time is spent here computing powers of two. I've read elsewhere
that flag values are cached, and it looks like negated Flag values can't be
cached? This seems related to the second issue, which is that any negated Flag
value being defined results in `RecursionError: maximum recursion depth
exceeded` as it searches for a good name for Flag.
Obviously, the simple workaround is just to define a constant variable
elsewhere with the negated value, but it isn't very obvious anywhere that this
is necessary, and I wanted to raise this to see if anyone has knowledge of the
implementation details of Flag for possibly resolving this in the class itself.

[issue42817] timedelta zeropadding hh
Kevin Rasmussen added the comment: Question: Why should it be zeropadded to 2? Answer: Why wouldn't it be zeropadded to match the rest of the library? Honestly it just seemed like an inconsistency with the rest of the datetime module. It caught me off guard when I went I tried to pull __str__ of a timedelta and the padding was different than what I saw elsewhere. I figured it could potentially be a quick fix if the current behaviour is not desired. I'm curious why that would have been rejected if it was even considered/noticed before. Do you know of any good way to figure out if this was discussed before? So far all I have done for searching was a search of issues that were already brought up and I didn't find anything at first glance. -- ___ Python tracker <https://bugs.python.org/issue42817> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Kevin Keating added the comment:
An __init__.py shouldn't be necessary. If I comment out the 'b =
lazy_import("foo.b")' line in a.py (i.e. disable the lazy import), then the
print statement works correctly as written without any other changes.
Also, I double checked with the colleague who originally ran into this issue,
and it turns out he encountered the bug on Linux, not on Mac (still Python
3.8.3).

[issue42273] Using LazyLoader leads to AttributeError
New submission from Kevin Keating :
Steps to reproduce:
Create the following three files (or download the attached zip file, which
contains these files):
main.py
import foo
from foo import a
from foo import b
print(foo.b.my_function())
foo/a.py
import importlib.util
import sys
# implementation copied from
https://github.com/python/cpython/blob/master/Doc/library/importlib.rst#implementing-lazy-imports
def lazy_import(name):
spec = importlib.util.find_spec(name)
loader = importlib.util.LazyLoader(spec.loader)
spec.loader = loader
module = importlib.util.module_from_spec(spec)
sys.modules[name] = module
loader.exec_module(module)
return module
b = lazy_import("foo.b")
foo/b.py
def my_function():
return "my_function"
and then run main.py
Expected results
my_function should be printed to the terminal
Actual results
The following traceback is printed to the terminal
Traceback (most recent call last):
File "F:\Documents\lazy_import\main.py", line 6, in
print(foo.b.my_function())
AttributeError: module 'foo' has no attribute 'b'
If you comment out "from foo import a" from main.py, then the traceback doesn't
occur and my_function gets printed. Alternatively, if you move "from foo
import a" after "from foo import b", then the traceback doesn't occur and
my_function gets printed. Adding "foo.b = b" before
"print(foo.b.my_function())" will also fix the traceback.
A colleague of mine originally ran into this bug when writing unit tests for
lazily imported code, since mock.patch("foo.b.my_function") triggers the same
AttributeError. I've reproduced this on Windows using both Python 3.8.3 and
Python 3.9.0, and my colleague was using Python 3.8.3 on Mac.

[issue42272] Warning filter message/module documentation is misleading
New submission from Kevin Locke : "The Warnings Filter" section of the documentation for the warnings module describes the message and module filters as "a string containing a regular expression". While that is true when they are arguments to the filterwarnings function, it is not true when they appear in -W or $PYTHONWARNINGS where they are matched literally (after stripping any starting/ending whitespace). Additionally, in the "Describing Warning Filters" section, the example "error:::mymodule[.*]" does not behave as described. If it were used as an argument to filterwarnings, where it would be treated as a regular expression, it would match the (invalid) module names mymodule. or mymodule* while it would match mymodule[.*] literally if passed via -W or $PYTHONWARNINGS. -- assignee: docs@python components: Documentation messages: 380429 nosy: docs@python, kevinoid priority: normal severity: normal status: open title: Warning filter message/module documentation is misleading type: enhancement versions: Python 3.10 ___ Python tracker <https://bugs.python.org/issue42272> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue42266] LOAD_ATTR cache does not fully replicate PyObject_GetAttr behavior
New submission from Kevin Modzelewski : The problem is that the descriptor-ness of a type-level attribute is only checked at opcache-set time, not at opcache-hit time. $ python3.8 test.py 2 $ ./python --version Python 3.10.0a2+ $ git rev-parse --short HEAD 789359f47c $ ./python test.py 1 -- components: Interpreter Core files: test.py messages: 380370 nosy: Kevin Modzelewski, pablogsal priority: normal severity: normal status: open title: LOAD_ATTR cache does not fully replicate PyObject_GetAttr behavior type: behavior versions: Python 3.10 Added file: https://bugs.python.org/file49568/test.py ___ Python tracker <https://bugs.python.org/issue42266> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue42225] Tkinter hangs or crashes when displaying astral chars
Kevin Walzer added the comment: Some work has been done this year on expanding support for these types of glyphs in Tk, but I'm not sure of its current state--it's not my area of expertise. Can you open a ticket at https://core.tcl-lang.org/tk/ so one of the folks working on this can take a look? -- ___ Python tracker <https://bugs.python.org/issue42225> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue42190] global declarations affect too much inside exec or compile
New submission from Kevin Shweh :
A global declaration inside a function is only supposed to affect assignments
inside that function, but in code executed with exec, a global declaration
affects assignments outside the function:
>>> gdict = {}
>>> ldict = {}
>>> exec('x = 1', gdict, ldict)
>>> 'x' in gdict
False
>>> 'x' in ldict
True
>>>
>>> gdict = {}
>>> ldict = {}
>>> exec('''
... x = 1
... def f(): global x''', gdict, ldict)
>>> 'x' in gdict
True
>>> 'x' in ldict
False
Here, we can see that the presence of a "global x" declaration inside f causes
the "x = 1" outside of f to assign to globals instead of locals. This also
affects code objects compiled with compile().
