In fact, there are several access channels, Usenet newsgroup is
one of them.

Another channel is the python-list mailing list.
You can subscribe to it on "python.org"
-- look for community/support --> mailing lists.
The maling list tends to have fewer spam then the newsgroup.

This is an unmoderated Usenet newsgroup.  It doesn't have members, just
people who post to it.  If you want to discuss Python, just post.  (Take
a look around first to get an idea how how thinks work.)

If you see a response from "Manosh Manosh", I recommend ignoring it.
He appears to be a spammer.

I had to read this closely. Yes, the second `put(1)` could execute
before the `join()` commences (or tests), and the `hello` would be
blocked still.


It seems that the whole point of join() is that 'hello' should always be
printed, but I just want to make sure that I understand it correctly.


That's the purpose of using `join`, but you need to use it correctly.
The "some tasks are not completed" condition which `join` supports
doesn't fit what you're doing.

So yes, you're correct in your concern.

Maybe 2 queues would suit you better? Maybe not if they are common.

I would go with 2 queues: 1 for input and 1 for output. The outputted 
item would be either a result or an indication of an error.

Maybe some kind of blocking counter, so that you could track task 
counts? You'd need to make one, but something which allowed:


count = queue.put(1)
queue.wait_for(count)
    print('hello')

and at the other end:

queue.get()
queue.task_done()   # bumps the counter
count2 = queue.put(1)

Here, the counter would not be the internal "unfinished tasks" counter 
but instead a distinct counter which always went up. Probably a pair: 
tasks submitted by `put` and tasks completed by `task_done`. You could 
subclass `JoinableQueue` and add implementations of these counters and 
add a `wait_for(count)` method.


This amounts to assigning each "task" a unique id (the counter) and a 
means to wait for that id.

[issue45842] AddressSanitizer: bad-free - hello world c extension

[Francesc Elies]

Francesc Elies  added the comment:

I am closing this one, bad-free is in this case a false positive.

Starting python and loading a dll which was linked with asan is incorrect.

One should asan-rt as earyly as possible, in order to do that in linux one 
should use LD_PRELOAD but in windows it's a bit more convoluted.

We made an executable which loads asan and instructed the dll DLLs to use the 
runtime linked into the main executable to avoid shadow memory collisions.

In the official docs https://clang.llvm.org/docs/AddressSanitizer.html I could 
not find much about asan with clang under windows. 

Despite the library file names where not the same as in llvm master and that 
the blogpost has msvc in mind instead of clang this blog 
https://devblogs.microsoft.com/cppblog/addresssanitizer-asan-for-windows-with-msvc/#contributions-to-asan-runtime
 pointed us in the right direction.

[issue45842] AddressSanitizer: bad-free - hello world c extension

[Francesc Elies]

Francesc Elies  added the comment:

I tested the same script in ubuntu and got the following.

==1361==ASan runtime does not come first in initial library list; you should 
either link runtime to your application or manually preload it with LD_PRELOAD.

While on windows he does not complain about ASan runtime not bein first in 
initial library list.

Once I use LD_PRELOAD in linux. Lsan detected memory leaks, after suppressing 
them with LSAN_OPTIONS=detect_leaks=0, the script ran fine.

So far I could not find an LD_PRELOAD equivalent in windows.

I am suspecting if one would compile python with asan and run the test on 
windows, I would get similar results as in linux. Sadly at the moment asan 
suppressions doesn't seem to work on windows.

I think this is not a real bug on python but the way we are loading asan-rt in 
windows. Once I am sure I will colse this bug.

[Francesc Elies]

New submission from Francesc Elies :

Hi,

Context
===
we are compiling a dll with clang and it's address sanitizer and loading it via 
cffi, at random spots ASAN complains with bad-free.

  ==15100==ERROR: AddressSanitizer: attempting free on address which was

  See links below for a full trace

The project where we see this it's quite complex and with many moving parts 
therefore we made a minimal reproducible example.

Reprex
==

The test boils down to the following:


win32api.LoadLibrary("LLVM-13.0.0-win64/lib/clang/13.0.0/lib/windows/clang_rt.asan_dynamic-x86_64.dll")
    import hello  # hello is our compiled c extension with clang and ASAN
print(hello.system())
import pdb


If if comment the last line (import pdb) ASAN does not complain.
If instead of import pdb you import numpy the same problem can be seen.

See the following failing build

We did not try this in linux yet, would that help?

Is this a bug? Or are we doing something wrong?

Thanks in advance for your time.

Apologies, my original post was unclear.

The help(app.quit) which I posted is what we should get when the method
isn't clobbered.

What Serhiy has posted is what you get after running the example as-is.  It
shows that after running the example self.quit refers to a button object
instead of the quit method.

That is very nasty. Fortunately Python is not gender-sensitive.

What Operating system do you use? I suppose it probably is Windows or Linux.
And did you use the installer from www.python.org?
These have an IDE that is called IDLE. It is simpler than Pycharm, but it can 
do the job. So you can try that. If that also gives an error you could try to 
reinstall Python.

If you are familiar with the command line, then that is also a possibility.

A clearer description of your situation would improve your odds
of getting a useful result.  For starters, what operating system
are you using?  What application presents the "modify tab" that
you mention?  Is this perhaps a problem with your software-installing
process, rather than with Python or with Pycharm?

Have you found a good Python tutorial?

Hello, I need help.

Dear Python Team,
First, I would like to introduce myself. My name is Damla Pehlivan, and I
live in Ankara/Turkey. I am a university student at Ankara University. My
major is Biology; therefore, I want to learn Python to use for Data
Science. When I researched and asked my professors, they suggested me to
learn Python.
 Sadly, I am quite a beginner but I downloaded the python program, and I
also downloaded Pycharm to use it. To be fair, I do not know what I am
doing, but I made some progress last night and I was happy about it. Today
when I came back from university, I realised the program was updated, I
updated it and now I cannot use it. When I clicked on it, it kept opening
the modify tab. I did modify it and repaired it. But it kept not opening
the actual program.
 I am writing this mail quite emotionally. I asked a new "friend" for help,
but he laughed. He said it was because I am a girl and this is why I could
not do it. I want to prove to him and the whole world that I can do it. I
have a lesson next Monday, so could you please help me with my problem?

[issue35086] tkinter docs: errors in A Simple Hello World Program

[Daniel Lovell]

Daniel Lovell  added the comment:

Thanks for the reply xtreak. I agree that changing the example to include 
main() isn't necessary - I unintentionally included that from my example of the 
case where the current version isn't functional. 

In the PR I submitted on Github (https://github.com/python/cpython/pull/10160), 
the proposed change is simply adding the master Tk instance to self.master then 
using that to close the window in the Quit button callback.

Sorry for the confusion.

[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

Thanks for the report. So the current example in the docs works fine since root 
is in global namespace. But this seems to be a sensible change to use 
self.master which references root instead of relying on root to be global 
though I don't know we should restructure the example to use main(). I am 
adding Serhiy for review.

[issue35086] tkinter docs: errors in A Simple Hello World Program

[Daniel Lovell]

New submission from Daniel Lovell :

In the documentation for tkinter, "A Simple Hello World Program" Application 
class does not hold onto the master Tk() instance as a class attribute. This is 
a good practice, and newcomers to tkinter would likely have trouble closing the 
window without this since root will almost never be in the global namespace.

The original example:

"""""

import tkinter as tk

class Application(tk.Frame):
def __init__(self, master=None):
super().__init__(master)
self.pack()
self.create_widgets()

def create_widgets(self):
self.hi_there = tk.Button(self)
    self.hi_there["text"] = "Hello World\n(click me)"
self.hi_there["command"] = self.say_hi
self.hi_there.pack(side="top")

self.quit = tk.Button(self, text="QUIT", fg="red",
  command=root.destroy)
self.quit.pack(side="bottom")

def say_hi(self):
print("hi there, everyone!")

root = tk.Tk()
app = Application(master=root)
app.mainloop()

""""

The proposed fix:

""""
import tkinter as tk

class Application(tk.Frame):
def __init__(self, master=None):
super().__init__(master)
self.master = master
self.pack()
self.create_widgets()

def create_widgets(self):
self.hi_there = tk.Button(self)
self.hi_there["text"] = "Hello World\n(click me)"
self.hi_there["command"] = self.say_hi
self.hi_there.pack(side="top")

self.quit = tk.Button(self, text="QUIT", fg="red",
  command=self.master.destroy)
self.quit.pack(side="bottom")

def say_hi(self):
print("hi there, everyone!")

def main():
root = tk.Tk()
app = Application(master=root)
app.mainloop()

if __name__ == "__main__":
main()

""""

That. Is. An. Adventure. If you plan on a multi touch experience I
recommend you look into #kivy and #python especially on freenode IRC

Well, that reads like an real adventure here. I've listening to books and
while it's different, you still enjoy the story, so maybe I can enjoy a
game made of sounds.

At some point, you might stop at the point where it pays the bills!

I attach a small program that does render jinja2 templates and markdown, I

Hi Daniel,

I'm unsure how well your support tools will work with quoted emails. I'm 
going to place my answer below your text according to the convention on 
this list.

First of all: Hello, and welcome. If you're a beginner to Python (or to 
programming in general) you might find the tutor list is a better place 
to start:


  https://mail.python.org/mailman/listinfo/tutor

But feel free to carry on posting here if you prefer.

If you want advice you'll probably need to ask a more or less focused 
question. The sort of thing you outline as an audio computer game sounds 
interesting and quite ambitious. I'm not clear if you've done any 
programming at all until now? If not, you'll want to start small and 
work up from there.


I'm not clear what's going on with your Windows Live Mail issue. The 
only (and obvious) thing I can suggest initially is to ask if someone 
closer to you can understand what's happening and advise. It's difficult 
to guess what's happened without getting closer to the problem.


Anyway, do post back here or to the Tutor list and ask if you any 
specific questions.

I'm afraid you would have to ask the vendors of the software you used to 
read the message with in the first place.  There is nothing particularly 
odd about this list that I can think of that might cause problems like that.

hello from a very excited and totally blind python programmer and game player

[Daniel Perry]

Hi there everyone, my name is Daniel Perry and I'm a totally blind new Python 
user. I've only just recently started picking up python and playing with it and 
I intend on building some unique audio computer games for the blind. Such 
things mostly as simulation games like farming, building type games and even 
eventually a virtual world built completely with audio but building it in such 
a way that both we as totally blind colonists can live inside of it but also 
that our fully sighted counterparts could live here as well and not need any 
sort of guidance from the other group. That is, the blind would not need any 
help from our sighted counterparts and you in turn would not need any guidance 
from us as to how to live in the world or grow in it. Of course this virtual 
world idea is down the road, I've got other game ideas first of all but I would 
eventually like to get to the point I've just described above. Preferably 
building my own server on which to park not only my virtual world and
  games but also my web site that I would most likely need to put these items

The _io__WindowsConsoleIO_write_impl() function should be fixed to not call 
MultiByteToWideChar() but use 0 if the input string is zero. Ok, it makes sense.

In that case, I agree to call it a simple issue ;-)

Eryk Sun  added the comment:

The error is in _io__WindowsConsoleIO_write_impl. If it's passed a length 0 
buffer, it still tries to decode it via MultiByteToWideChar, which fails as 
documented. As Serhiy says, it can simply return Python int(0) in the 
zero-length case.

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

I don't know which part of _WindowsConsoleIO.write() fails to handle empty 
bytes string, but the simplest and the most efficient way to fix this bug it to 
add an explicit check for zero length at the begin of this method and return 
Python integer 0 in this case.

The test should check that sys.stdout.buffer.write(b''), 
sys.stdout.buffer.write(b'') and sys.stdout.buffer.raw.write(b'') return 0 (the 
latter to checks should be performed only if the corresponding buffer and raw 
attributes exist). There are special tests for WindowsConsoleIO, it would be 
nice to add an explicit test here too.

[issue31966] print('hello\n', end='', flush=True) raises OSError when ran with py -u

[Guillaume Aldebert]

New submission from Guillaume Aldebert <galdeb...@gmail.com>:

noticed on windows10, 3.6.3-64 and 3.7.0a2-64:

using this test.py file:

#!/usr/bin/env python3
print('hello\n', end='', flush=True)

and running it in unbuffered mode:

C:\Dev>py -u test.py
hello
Traceback (most recent call last):
  File "test.py", line 2, in 
print('hello\n', end='', flush=True)
OSError: [WinError 87] The parameter is incorrect

Note that (still using py -u):

print('hello', end='', flush=True) # works fine
print('', end='', flush=True) # raises OSError as well

You cannot attach a screen shot to the newsgroup.

Building TensorFlow with GPU support is not simple.  It involves far more than 
Python.  I am investigating this issue myself.  Check tensorflow.org for more 
information.  Also, there is a TensorFlow newsgroup hosted on Google Groups.


There is also a tensorflow tag on Stackoverflow with lots of questions 
and, I hope, helpful answers.



But before you take the trouble, are you sure that you need GPU support right 
away?  You can explore neural nets on a CPU-only system, and in that 
configuration, TensorFlow installs easily.

Hello,

you can refactor your code a little bit and learn more about exceptions:

def get_numbers():
first = None
second = None
while True:
try:
if first is None:
first = int(input('Enter your first number: '))
if second is None:
second = int(input('Enter your second number: '))
except ValueError:
print('You have to enter a number')
continue
else:
return first, second

It helps if you describe what is going wrong.  Not just us, either; 
"Teddy Bear Debugging", explaining to a colleague (or indeed a soft toy) 
why your code cannot possibly be wrong, is an excellent way of finding 
bugs.  The number of times I've stopped in the middle of an explanation 
to fix the now glaringly obvious mistake...


Try it and see.  Here's a hint: be very aware of what your indentation 
means.

You haven't said what the problem is.

It looks OK, apart from the indentation, which is important to get right 
in Python.


Also, you've defined a function 'main' but not called it, and imported a 
module but not used it, which is pointless.

Then not only was he an arse but he is also wrong.
for a complex problem it is best to have a plan on how to implement it 
before reaching for the keyboard.

Your answer of get the spec & requirements certainly does not need a 
computer (although one could help for note taking if your hand writing is 
as bad as mine).

I guess he was so caught up with his clever catch answer that he did not 
bother to analyse yours & realise he had missed something

"I decided then and there I did not want to work for that guy."

Shame I would have enjoyed reading the results on www.thedailywtf.com :-)

I'm reminded of a wonderful scene from an old movie called "Those
Magnificent Men In Their Flying Machines". Set some time in the early 20th
century, before World War 1, it's about an international aeroplane race
across the English Channel. One of the pilots is an Englishman, played by
Terry Thomas, who of course plays a bounder and a cad, so he tries to
sabotage the other contestants so he can win the race. He manages to give
the German pilot an overdose of laxative to put him out of the race.

The German's commanding officer, a great big fat Prussian colonel, decides
that with German discipline and planning anyone can be a pilot, so he takes
the German army Flying Machine instruction manual, climbs into the plane's
cockpit, and standing proudly, opens the book to the first page and reads:

[Hollywood German accent]
"Step One: Sit Down!"

Many years ago (c. 1985) I was at a job interview and the interviewer asked
me what the first thing I would do when I am presented with a new problem
that I had to code up. I gave all sorts of answers like 'do a top down
analysis of the problem,' and 'get the specs and requirements,' and 'write
a flow chart.' Each time the interviewer said no even before that. Finally
I said, what, what would do first? He said "Turn the computer on." I

Make sure your computer is turned on. I can't tell you how many times I've
tried to install Python, and I type commands and click icons and nothing
happens. It's really frustrating when you finally realise that the reason
nothing is working is because the computer is turned off! (I thought I just

If that's not your problem, I'm afraid you'll have to tell us what you
tried, and what results you got. Remember that we're not watching you
install, so we have no idea of what you did. 

What version of Python did you try to install?

Where did it come from? Give us the actual URL, don't just say "from the
website". 

What OS are you running? What version? 32-bit or 64-bit?

How did you install it? What commands did you type?

What happened? Did you get an error message? What did it say? Please COPY
and PASTE any results if you can. Don't post a screen shot, because this

Given that path, you have a very strangely configured Windows system...



All change with 3.5, so that looks about right for a default user

Hey, don't put this on being created for multiple OSes. Unix and Mac
both supported spaces in filenames, at the OS level, *long* before
Windows did. Programs that break on encountering them are broken

you might want to try activestate's version from

3.5 isn't available there yet, but it otherwise has

Hello

[Phuong Phan]

Hi Python community,
I am new to Python and currently taking one online course of computer
science and programming using Python. I really like Python because it is
simple and clarity but powerful to me.
I just joint Python mailing list and i hope to enjoy Python programming
discussion with you all.
Thank you,

Hello Group and how to practice?

[Anders Johansen]

Hi my name is Anders I am from Denmark, and I am new to programming and python.

Currently, I am doing the codecademy.com python course, but sometime I feel 
that the course advances to fast and I lack repeating (practicing) some of the 
concepts, however I don't feel confident enough to start programming on my own.

Do you guys have some advice to how I can practicing programming and get the 
concept in under the skin?

Thanks!

Choose something that you think is small and easy to do, and try to do it.  
When you have trouble, read the docs you find online, and ask us questions; the 
python community is pretty friendly, and if you show us what you've already 
tried to do, someone is likely to try to help you out.

The main thing is to not get discouraged.  One of the hardest things to do is 
figuring out what you CAN do with a computer; some things that look like they 
should be easy, are actually major research questions.  Just keep trying, and 
it will get easier over time.

Good luck!

Thank you Cem Karan for your reply. I will try and follow your advice. I am yet 
to install python on my computer, do you know of any easy to follow 
instructions on how to do so? Where do I start?

Python 3 installers are here: 
https://www.python.org/downloads/release/python-343/  Choose the one 
appropriate for your system, and follow the instructions.  If you have trouble, 
write to the list.

Good luck,

I am trying to help a buddy out. I am a C++ on Windows guy. This buddy
of mine is learning Python at work on a Mac. I figured I could
contribute with non language specific questions and such.

When learning any new language, I said, the first step would be a Hello
World program. Let's see if we can get that to work.

So my buddy creates opens the IDE they gave at the workplace, creates a
new project, adds a demo.py file, writes one line : print Hello World,
hits Run in the IDE and indeed the display is shown at the bottom when
it executes.

I say the next step would be to get that to run on the command line. So
(keep in mind I know nothing about macs) my buddy opens a zsh? window,
cd to the directory, and I say the command i most likely: python demo.py

It looks like it executes but there is no output to the command line
window.


It should.  In a Windows console, using 3.4:
C:\Programs\Python34type tem.py  # cat on Mac?
print('Hello World!')

C:\Programs\Python34python tem.py
Hello World!

 Can anyone explain why there is no output?

Without a copy of the file and command, as above, no.

 Can anyone recommend a good walkthrough of getting set up and doing 
basics?


Since you used 2.x  print syntax: https://docs.python.org/2.7/

 I'll probably end up learning python myself, just to help out.

You might possibly enjoy Python as a complement to C++.  Some people 
prototype in Python and rewrite time critical functions in C++.  One can 
access .dlls either directly (via the ctypes module) and write a wrapper 
file in C or C++.  I believe Python has also been used to write tests 
for C++ functions (I know this is true for Python and Java, via Jython).

Generally we use Google Hangouts - video chat, with options for
screen-share (replacing the camera; let's face it, when you're
discussing code, staring at talking heads isn't all that useful) and a
few other neat features. But if uniformity is an issue, you might want
to look into some kind of virtual Linux box like http://nitrous.io/ -
that way, everyone's using the same system, and nobody has to worry
about the stupid hassles of trying to support three different OSes.
Though Nitrous mightn't be as important for you as it is for the
Thinkful course; as part of the course, we teach PostgreSQL + Python +
PsycoPG2 + SQLAlchemy, and if you're on a Mac and your student is on
Windows, you'll *really* appreciate not having to figure out how to
install that lot on a foreign platform! (In theory, the situation
should be getting better. Installing stuff from PyPI under Windows has
long been a massive nuisance, but it's starting to become a bit
easier. But it's still a massive pain for someone who doesn't know
Windows to try to walk a Windows person through the setup.)

And hey. If you want a pay-for Python programming course, do check 'em
out - www.thinkful.com. You get regular one-on-one mentorship, a
highly responsive team of staff, and all sorts of random fun. There,
I'm done advertising now. :)

Good docs. I got setup in Windows in 10 minutes.
