[issue38808] weird bug while using a for loop and array
Zach kuunka added the comment: I found out it just happens when you set an array to an array they behave as the same thing, which if its not a bug it sure is counter-intuitive. if you do x = 1 then y = x then add one to y you have y = 2 and x = 1 if you do it for an array arr1 = [1] then set something equal to that arr2 = arr1 you essentially have 1 var that act on each other which is odd so arr2.append(2) or arr1.append(2) make both arr1 and arr2 equal to the same thing -- ___ Python tracker <https://bugs.python.org/issue38808> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue38808] weird bug while using a for loop and array
New submission from Zach kuunka : I haven't used this bug reporting thing before so sorry if I mess something up. Anyway i'm not sure exactly what is causing the issue but the issue appears when you have a for loop looping through an array and you make a variable and set it to that array and append something to it. If you do the same thing with numbers it works as expected but if you do it with an array it for some reason doesn't get reset every iteration. Run this and you'll see what i'm talking about. Arr = [1,2,3,4,5] for num in Arr: Arr2 = Arr Arr2.append(1) #the 1 can be anything print(Arr2) Also i'm interested to know why this happens, Thank You -- components: Library (Lib) files: brokentest.py messages: 356648 nosy: Zach kuunka priority: normal severity: normal status: open title: weird bug while using a for loop and array type: behavior versions: Python 3.6 Added file: https://bugs.python.org/file48716/brokentest.py ___ Python tracker <https://bugs.python.org/issue38808> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue37564] ArgumentParser should support bool type according to truth values
New submission from Zach Beniash :
Today when using argparse.ArgumentParser it seems that the bool type is not
supported in a logical way.
Foe example:
-
import argparse
parser = argparse.ArgumentParser()
parser.add_argument("--mybool", type=bool)
parsed_args = parser.parse(["--mybool", "False"])
--
parsed_args.my_bool evaluates to True
Instead we should expect to evaluate False here.

Dataframe iterating question : 3 ways of calling a row and column
I wouldn't say I'm a Python noob, but I wouldn't say I'm a Python expert either. I work in data science and use Pandas Dataframes a lot. My question is regarding the difference in calling out a specific row, column combination in a dataframe. I see 3 ways of doing this: (1) df.loc[row_ind, column_ind] (2) df.column_ind.loc[row_ind] (3) df[column_ind].loc[row_ind] where column_ind is the column name & row_ind is the named row index/row name in the dataframe. Can anyone enlighten me as to the differences between the above 3 methods of getting to the same cell in the dataframe? Are there speed differences? Is it simply a preference thing? Is there a PEP8 preferred way of doing this? Are there specific disadvantages to any of the methods? Thanks in advance. Zach -- https://mail.python.org/mailman/listinfo/python-list
[issue29335] subprocess module does not check WIFSTOPPED on SIGCHLD
Zach Riggle added the comment:
Neat, though that's not in the standard library.
The current logic for getting a handle to libc could also be simplified via
ctypes.util.find_library
(https://docs.python.org/3/library/ctypes.html#finding-shared-libraries).
Darwin:
>>> import ctypes.util
>>> ctypes.util.find_library('c')
'/usr/lib/libc.dylib'
Linux:
>>> import ctypes.util
>>> ctypes.util.find_library('c')
'libc.so.6'

Zach Riggle added the comment: To further clarify the report: When the attached proof-of-concept is executed, a RuntimeException is raised, which has a comment "Should never happen".

These lines here: https://github.com/python/cpython/blob/2.7/Lib/subprocess.py#L1036-L1038 The root cause is a lack of checking WIFSTOPPED and WSTOPSIG in the handler. When a process elects into being ptraced via PTRACE_TRACEME, it is stopped on the SIGSEGV instead of terminating, allowing the user to attach a debugger before the kernel destroys the process.

"perf.py -r -b all python patched_python" vs "perf.py -r -b all patched_python python" bench_results.txt has the actual output in it, and the "slower in the right column" comment was referring to the contents of that file, not the table.

It applied cleanly, and the benchmark results were similar, this time unpack_sequence and spectral_norm were slower. Spectral norm makes sense, it's doing lots of FP addition. The unpack_sequence instruction looks like it already has optimizations for unpacking lists and tuples onto the stack, and running dis on the test showed that it's completely dominated calls to unpack_sequence, load_fast, and store_fast so I still don't know what's going on there. -- ___ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21955> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Python Requests logging 401 immediately before 200
Hi everyone,
I'm using MarkLogic and have a Python script set up to check for documents
using Requests (http://docs.python-requests.org/en/latest/) and I have logging
included in the script.
I have logging set to the DEBUG level.
When I set the script to simple search and return the HTTP status code for
items it works, but when I look at what is generated by logging I see the
following for everything:
INFO:requests.packages.urllib3.connectionpool:Starting new HTTP connection (1):
localhost
DEBUG:requests.packages.urllib3.connectionpool:GET
/v1/documents?uri=000248e4331d4db5856df8fd427b3cdb.xml HTTP/1.1 401 211
DEBUG:requests.packages.urllib3.connectionpool:GET
/v1/documents?uri=000248e4331d4db5856df8fd427b3cdb.xml HTTP/1.1 200 18327
As you can see the 400 and the 200 are the same document (only 1 can exist in
ML with the same URI) and in MarkLogic's logs both are executed at the same
time.
When I search for a document using something like CURL for instance, I only get
the 200 status code which seems correct to me.
Is this something I should be concerned about and should fix or is it just the
log level I have set or something else I shouldn't worry about?
Thank you for your help!
Here's a snipped of my code in case it helps:
import requests
import logging
# initiate logging
log_path = os.path.join('my_log.log')
logging.basicConfig(filename=log_path,level=logging.DEBUG)
# make request
r =
requests.get('http://localhost:8004/v1/documents?uri=000248e4331d4db5856df8fd427b3cdb.xml',auth=HTTPDigestAuth('USER',

Short explanation: It's part of the protocol.
You're using Digest Auth, so what's happening here is that a request
is sent without the authentication, and the inevitable 401 response is
the signal that the request should be re-sent with credentials.
There's a massive debate as to whether or not it's correct to send
unsolicited credentials. On the one hand, this 401 then 200 pattern
takes extra internet round-trips (not that that's a big deal with
localhost, but it's the same issue everywhere) and puts extra load on
both server and client; but on the other hand, nobody wants their
credentials sent to the wrong server, and it's not always easy to tell
when they'll be needed. Without the 401, you can't know whether or not
you need to authenticate, so if once you start sending unsolicited
credentials, you basically have to keep on doing so.
If you don't have a problem with performance or latency, then consider
this to be nothing more than a bit of log file spam. I'm not sure if
the Python requests module can be easily configured to send
credentials on the first query, but my advice is: don't even bother
looking into that unless you have need to.
All the best!
ChrisA
Thanks very much for this it's extremely helpful! This clears it up and I think
I will ignore it as log spam as you suggest.

For various reasons, we must use cross-compiling on a Linux host, so the advice to use a native compiler is moot for our situation. Certainly, documenting the absense of the 64-bit library would be good. Providing a documented script to generate one is better. Providing the library would be ideal, if there will not be forward compatibility or runtime issues. It would be nice to see concrete details about the current state of affairs. The cython project's warning would carry more weight with me if it contained links to specific details: mailing list discussion that led to the deliberate decision to omit the 64-bit library, bug reports filed against the mingw-w64 project about the runtime issues, etc.. That said, such details probably do exist, but my cursory searching has failed to turn them up. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23199 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue23199] libpython27.a in amd64 release is 32-bit
Zach Welch added the comment: Yes, pe-i386 and pe-x86-64 are the respective 32-bit and 64-bit object formats. Your commands seem reasonable. With gendef, I just let it create a .def file with the same name (i.e. skip the '-' and redirection); in my mind, that reinforces the association between the dll and def files. With dlltool, I did not have to use the -m flag (as x86-64 is the default for me), but I don't see anything wrong with being explicit. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23199 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue23199] libpython27.a in amd64 release is 32-bit
Zach Welch added the comment: The libpython27.a is an actual 32-bit version, as confirmed by running objdump -t on it. It reports the sections' file format as pe-i386 instead of pe-x86-64. I am only using it for building for the 64-bit target, so I cannot confirm its viability for 32-bit builds. To build 64-bit Windows binaries, you need a MinGW-w64 toolchain (which is a completely separate project from the original MinGW project). The target triplet is x86_64-w64-mingw32. I cannot speak to the stability of the MinGW-w64 library interface, but I would expect it to be stable. To wit, I would be shocked if future changes required regeneration of third-party .a files. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23199 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Zach Mathew added the comment: To Ezio's first point ... yes, I was wondering if trailing whitespace should be left alone in the case of an explicitly defined separator. However, this behavior seems a little odd to me as I don't see a use case for it (happy to change the patch if there are differing opinions on this).

The only perspective that I think of is that class might instantiate a function several time. For my use I don't have multithread and mostly programs are sequencial. I had a hard time with this at first when I started using Python. I personally come from a background of using Java in an educational environment, so I'm pretty familiar with it. Going from a pure Object-Oriented language, where everything MUST be bundled into a class, and an Object is less of a bit of data and more of a data structure that actually DOES something, was a little difficult. Just repeat this to yourself: Python ISN'T Java. Repeat it until the words start sounding funny to you. Then continue for another 10 minutes. It'll sink in. Anyhow... In Python, classes aren't necessarily treated as things that do stuff (though they can DEFINITELY act in that way!). Python classes are made to hold data. If you have something that you need to save for later, put it in a class and call it a day. If you only have a bunch of functions that are meant to process something, just put them into a module. You'll save yourself some time, you won't have to instantiate a class in order to call the functions, and you'll be happier overall.

For zip(*arr) to work properly, each line of arr should have the same
length, which means that either each value of d has the same length or
that you find the max length and pad lines with blanks up to the max
length. The code above assumes the first.
If the items in each value of d are not strings, more fiddling is
needed. The printed field size is also arbitrary. It needs adjusting for
the actual max length. You might want to adjust it for each key-value
pair in the dict, which is to say, each column of the resulting table.

I just have one quick question. On the line where you have zip(*arr),
what is the * for? Is it like the pointer operator, such as with C? Or
is it exactly the pointer operator?
Otherwise, thank you for the example! This isn't homework, but I'm
working on something at work, and I was wondering how to properly
format the output from CSV files into another file. It's all a part of
an analyzer script for database tables, and the table wherein. Thank

Mimicing an HTML form
Hi all,
I'm having alot of trouble automating the submitting of form. I have an
HTML page that works and it looks like this:
form action='*script here*' enctype=multipart/form-data method=post
input name=txtTitle id=txtTitle value=Video Title maxlength=50
/BR /
input type=file id=FileUploadedVideo name=FileUploadedVideo /BR /
input name=txtDescription id=txtDescription value=Description
maxlength=50 /BR /
input id=hdnADCID name=hdnADCID value=*app ID here* type=hidden /
input type=submit value=Submit /
/form
When I put valid values for the handling script an app ID, this page works.
Now I'm trying to turn this same functionality into a script. Here's my
code:
import urllib
import os
import urllib2
appID = *value here*
video = os.path.normpath(os.getcwd() + '/news.wmv')
title = 'News'
desc = 'Here is a sample News video'
uploader = *script here*
print Encoding url...
data = urllib.urlencode({FileUploadedVideo: video,
hdnADCID : appID,
txtTitle : title,
txtDescription: desc})
user_agent = 'Mozilla/4.0 (compatible; MSIE 5.5; Windows NT)'
headers = { 'User-Agent' : user_agent }
print Calling url...
req = urllib2.Request(uploader, data, headers)
response = urllib2.urlopen(req)
s = response.read()
response.close()
print Writing results...
result = open('result.html','w')
result.write(s)
result.close()
Does anybody have any suggestions? I keep on getting bad request, so I'm
assuming that the html page is passing something that my script is not. Is
there some way to scrape the POST request from the html form?
Thanks,
Zach

Re: Config files with different types
yaml looks pretty interesting. Also, I wouldn't have to change much,
I would still use the same function, and still output a dict.
Thanks!

Hello,
Have you considered using something that is already developed?
You could take a look at this presentation for an overview of what's
available:
http://us.pycon.org/2009/conference/schedule/event/5/
Anyway, let me explain that, since I discovered it, my favourite
format for configuration files is yaml (http://yaml.org/,
http://pyyaml.org/). It's easy to read, easy to write, available in
different programming languagues, etc. In addition to this, type
conversion is already in place so I think it covers your requirement.
For example:
IIn [1]: import yaml
In [2]: yaml.load(name: person name
...: age: 25
...: is_programmer: true)
Out[2]: {'age': 25, 'is_programmer': True, 'name': 'person name'}

Hi all,
I've written a function that reads a specifically formatted text file
and spits out a dictionary. Here's an example:
config.txt:
Destination = C:/Destination
Overwrite = True
Here's my function that takes 1 argument (text file)
the_file = open(textfile,'r')
linelist = the_file.read().split('\n')
the_file.close()
configs = {}
for line in linelist:
try:
key,value = line.split('=')
key.strip()
value.strip()
key.lower()
value.lower()
configs[key] = value
except ValueError:
break
so I call this on my config file, and then I can refer back to any
config in my script like this:
shutil.move(your_file,configs['destination'])
which I like because it's very clear and readable.
So this works great for simple text config files. Here's how I want
to improve it:
I want to be able to look at the value and determine what type it
SHOULD be. Right now, configs['overwrite'] = 'true' (a string) when
it might be more useful as a boolean. Is there a quick way to do
this? I'd also like to able to read '1' as an in, '1.0' as a float,
etc...
I remember once I saw a script that took a string and tried int(),
float() wrapped in a try except, but I was wondering if there was a
more direct way.
Thanks in advance,
Zach

Executing a python script while it is running
Hi everybody, Here's my situation: I have a batch file that calls a python script. This batch file is triggered by an outside application when the application completes a task. The problem is that while the batch file (and pythons script) is running, the application will complete the next task, and try to call the batch file again (while it is already running) Hopefully that's not too confusing. I'm not sure what direction to go with this, any help or nudges in the RIGHT direction would be greatly appreciated. -- http://mail.python.org/mailman/listinfo/python-list
Re: Executing a python script while it is running
A lot more information would be useful. What version of Python, and what operating system environment? Exactly what would you like to happen when the batch file is invoked a second time? I'm running Python 2.6.2 on Windows. I'm passing filenames to the batch files and I need all filenames to be processed. I can't have any fails. I'm working on logging any fails I do have so that I can maybe batch process at the end of the day. 2) let them both run as separate processes This sounds like a good option, but I'm not totally sure on how to go about this? 4) queue something to be processed when the first run finishes I had the same idea, but I believe it would involve having another python script run all day long, which wouldn't necessarily be a bad thing, but I'd like to explore other options as well. What provisions does this existing application have for long-running batch files? Seems the synchronization ought to happen there. Do you have any constraints on how long your script might take, worst case? What if the application finishes its tasks at a faster average rate than your script can process them? The batch file is moving large video files. Duration probably ranges from 10 sec to 45 mins. On average, the application takes longer to process the files than it does the batch file/python script takes to copy them, but I'm concerned about the occasional time that the application finishes a small file right after finishing a large file. Thanks for your response! -Zach -- http://mail.python.org/mailman/listinfo/python-list

Option 2 is what you get by default. Naturally it depends on what the application is using to launch the batch file, but the most common cases will launch a separate process. The app ended up delaying starting the second batch file until it finished the first. I had the app trigger an infinite loop on completion, and sent two files through at the same time. The second file finished seconds after the first, but the batch file didn't trigger until I closed the first one. Are you sure you aren't unknowingly having the app wait on the first batch file process until it terminates? How exactly are you launching the batch files? Cheers, Chris -- http://blog.rebertia.com Hey Chris, I actually think that's what's happening, which is fine in my case (for now anyway) as I just need them all to complete, we don't need them running at the same time. I'm using a job management system, and they have the option of triggering a command line after completing a job. A better/safer solution might be spawning another job and re-inserting to the jms queue. Thanks again, Zach -- http://mail.python.org/mailman/listinfo/python-list

[issue2889] curses for windows (alternative patch)
Zach Hirsch zhir...@umich.edu added the comment: * test_curses: I'd be happier to see the 'if' statement as sys.platform != 'win32' and (not term or term == 'unknown') -- easier to read. OK, fixed. * test_curses: does putp() make PDCurses crash, or is it not available? If the latter, I'd prefer to see 'if hasattr(curses, putp): putp test'.Same for the tparm() test. They're stubs in pdcurses that always return an error. I'm not sure which is better in this case -- make them available through the curses module but always raise an exception on Windows, or make them unavailable and have it be an AttributeError if something tries to call them on Windows. * Given that you include term.h and IRIX included term.h, I wonder if we should make _cursesmodule.c include term.h on all platforms that have it, and then fix the resulting breakage claimed by the comment (if any). Yea, it was actually really easy to resolve the conflicts. I've done that, and tested the result on Linux and OS X 10.4. * Is setupterm() a no-up on Windows? Maybe the function just shouldn't be defined on Windows, then, so that user code can check for the function's existence. PDCurses does the same thing for setupterm as it does for putp/tparm (and a number of other unsupported functions) -- always returns an error. However, the curses module keeps track of whether it's been initialized based on whether setupterm has been called, so I think it makes sense to keep setupterm available but not call PDCurses's setupterm function on Windows. -- message_count: 4.0 - 5.0 Added file: http://bugs.python.org/file13282/python-pdcurses-2.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue2889 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue4541] Add str method for removing leading or trailing substrings
Zach Hirsch [EMAIL PROTECTED] added the comment:
Thanks for taking a look.
Yea, it's pretty easy to write it in Python, but I've found that I've
needed it in quite a few things that I've worked on, so I thought it
might be useful in Python itself.
I've updated the patch to fix the reference leak.
I could imagine someone wanting to strip the same string from both
sides, e.g. -- hello --.strips('--').strip() == hello. It might also
be a good idea to include str.strips for parallelism with str.strip.

Shared script
I wrote a script that several different people on different machines need to run on a regular basis. When I first wrote it, it was in crisis mode, I got something out that was quick and dirty, very bare bones. Recently I had some more time, so I pushed most of the functions that the script uses into a module, because I use those functions on a pretty regular basis. My problem is this: The module is on MY machine in MY Python25 folder. I like it there, because like I said, I use the functions within it on a pretty regular basis. However, the other people who need to run the original script don't have the module. My quick fix was to throw the module into the shared folder, which works, but means everytime I have to update the module I have to update 2 different files, the one in my Python25 folder and the one in the shared network folder. Is there a better way to do this, short of asking everybody else to put the module in thir Python 25 folder (which would mean me e-mailing them to update the module, and then assuming that they did) ?!?
