ANN: dh-virtualenv 0.5 released
Hi, We (Spotify) have released the first public release of dh-virtualenv, a packaging tool that makes it possible to package virtualenvs inside Debian packaging. dh-virtualenv works by registering itself as a part of debhelper sequence, so pretty much any pre-existing Debian build system you have should be compatible with it. dh-virtualenv is released under GPL version 2 or later. Source code for it can be found here: https://github.com/spotify/dh-virtualenv Documentation: http://dh-virtualenv.readthedocs.org/en/latest/ ..and the accompanying release blog post: http://labs.spotify.com/2013/10/10/packaging-in-your-packaging-dh-virtualenv/ Cheers, Jyrki Pulliainen Software engineer @ Spotify -- https://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/
ANN: matplotlib 1.3.1
I'm pleased to announce the release of matplotlib version 1.3.1. This is a bugfix release. It may be downloaded from here, or installed through the package manager of your choice (when available): http://matplotlib.org/downloads The changelog is copied below: New in 1.3.1 1.3.1 is a bugfix release, primarily dealing with improved setup and handling of dependencies, and correcting and enhancing the documentation. The following changes were made in 1.3.1 since 1.3.0. Enhancements - Added a context manager for creating multi-page pdfs (see `matplotlib.backends.backend_pdf.PdfPages`). - The WebAgg backend should no have lower latency over heterogeneous Internet connections. Bug fixes ` - Histogram plots now contain the endline. - Fixes to the Molleweide projection. - Handling recent fonts from Microsoft and Macintosh-style fonts with non-ascii metadata is improved. - Hatching of fill between plots now works correctly in the PDF backend. - Tight bounding box support now works in the PGF backend. - Transparent figures now display correctly in the Qt4Agg backend. - Drawing lines from one subplot to another now works. - Unit handling on masked arrays has been improved. Setup and dependencies `` - Now works with any version of pyparsing 1.5.6 or later, without displaying hundreds of warnings. - Now works with 64-bit versions of Ghostscript on MS-Windows. - When installing from source into an environment without Numpy, Numpy will first be downloaded and built and then used to build matplotlib. - Externally installed backends are now always imported using a fully-qualified path to the module. - Works with newer version of wxPython. - Can now build with a PyCXX installed globally on the system from source. - Better detection of Gtk3 dependencies. Testing ``` - Tests should now work in non-English locales. - PEP8 conformance tests now report on locations of issues.

I also like the idea of a helper function given by Peter Otten at 09.51. It still seems like a crutch to help poor old Python 2.X to do what any programmer (or, at least the programmers like me :-) ) think it ought to be able to by itself. The distinction between the geekiness of a tuple compared with the non-geekiness of a string is, itself, far too geeky for my liking. The distinction seems to be an utterly spurious - even artificial or arbitrary one to me. (Sorry about the rant.) I agree, and that's not how I would explain the distinction. The str of an object is meant to be human-readable, while the repr of an object is meant to be something that could be pasted into the interpreter to reconstruct the object. In the case of tuples, the repr of the tuple uses the reprs of the components because the resulting string will more likely be acceptable to the interpreter, and the str of the tuple is the same as the repr because there is no convincing reason why it should be different. -- https://mail.python.org/mailman/listinfo/python-list
Re: ANN: CUI text editor Kaa 0.0.4
Hi, Thank you for your question. What's a console user interface? That's what Windows calls a DOS box. But otherwise you seem to imply it runs on Linux. I meant to say something like DOS box or Linux terminals. Unfortunately, Kaa does not work on Windows DOS box since Kaa requires curses library to run. So, what OS's does it support? Which terminal programs? Currently, Kaa is tested on Mac OS X 10.8.5 and Ubuntu 13.04 box. I usually use iTerm2 on Mac and Gnome Terminal on Ubuntu. Does it only work locally, or can it work from an ssh terminal? Works for both locally and ssh terminal. Can it run within screen? Yes, but as Emacs or bash, default escape character of screen(^A) conflicts with Kaa,. So I recommend to assign another character for screen.

What version of glibc is Python using?
I'm trying to find out which version of glibc Python is using.
I need a fix that went into glibc 2.10 back in 2009.
(http://udrepper.livejournal.com/20948.html)
So I try the recommended way to do this, on a CentOS server:
/usr/local/bin/python2.7
Python 2.7.2 (default, Jan 18 2012, 10:47:23)
[GCC 4.4.6 20110731 (Red Hat 4.4.6-3)] on linux2
Type help, copyright, credits or license for more information.
import platform
platform.libc_ver()
('glibc', '2.3')
This is telling me that the Python distribution built in 2012,
with a version of GCC released April 16, 2011, is using
glibc 2.3, released in October 2002. That can't be right.
I tried this on a different Linux machine, a desktop running
Ubuntu 12.04 LTS:
Python 2.7.3 (defualt, April 10 2013, 06:20:15)
[GCC 4.6.3] on linux2
('glibc', '2.7')
That version of glibc is from October 2007.
Where are these ancient versions coming from? They're
way out of sync with the GCC version.

Why isn't this code working how I want it to?
I've been working on a program and have had to halt it due a slight problem.
Here's a basic version of the code:
a = 'filled'
b = 'filled'
c = 'empty'
d = 'empty'
e = 'filled'
f = 'empty'
g = 'filled'
testdict = {a : 'apple' , b : 'banana' , c : 'cake' , d : 'damson' , e : 'eggs'
, f : 'fish' , g : 'glue'}
Now what I want to do, is if a variable is filled, print it out. This however
isn't working how I planned. The following doesn't work.
for fillempt in testdict:
if fillempt == 'filled':
print(testdict[fillempt])
All this does though, is print glue, where I'd want it to print:
apple
banana
eggs
glue
Perhaps a dictionary isn't the best way to do this.. I wonder what else I can
do...
Thanks for any help.

Hi,
Remember that keys in a dictionary are unique. So if you defined ( means it
I typed it at the interactive terminal prompt,
d = { 'filled' : 'apple' , 'filled' : 'orange' }
and do a
print d
it will show:
{'filled': 'orange'}
One way to solve this problem is to define two dictionaries.
One holding the status of the variable, the other one holding
the data. For example:
status = { 'a' : 'filled', 'b' : 'empty', 'c' : 'filled' }
data = { 'a' : 'orange', 'b' : 'apple', 'c' : 'banana' }
for k in status:
if status[k]=='filled':
print data[k]
Regards and let us know if it works for you,
Marco

You have duplicate keys here, which becomes obvious when you spell out the

testdict = {filled: apple, filled: banana, ...}
When you do that, the last value (banana) wins, all others (e. g. apple)
are dropped.

A dictionary is spot-on, but you have to use the unique apple,
banana,... as keys:
status = {apple: filled, banana: filled, cake: empty}
for item in status:
... if status[item] == filled:
... print(item)
...
apple
banana
Could it be that you just confused dict keys with dict values?

You've effectively set up a dictionary with keys 'filled' and 'entries'
which you can see if you run this loop
for key, value in testdict.items():
print(key, value)
which gives me this
empty fish
filled glue
I'm too lazy to type anything else so please refer to this

I'll also leave the argument over whether it's a variable or a name to
others :)

But most classes don't make an attempt to create a Python expression, because that's very difficult Well, it's not actually difficult. You could imagine doing something like: def __repr__(self): return pickle.loads(%s) % pickle.dumps(self) and while you can paste that into a REPL, it's not really useful to most people. What we do with our database model layer is have the repr include the name of the class and the primary key. So: str(u) 'roysmith' repr(u) User 1000564: u'roysmith' That follow's Ned's idea that reprs should be unambiguous. In this case, if I want to reconstitute myself as an object, I can just do a database query for user_id = 1000564. -- https://mail.python.org/mailman/listinfo/python-list

Error connecting to MySQL from Python
Hello guys I am currently working in a python project at my school. First I
want to make clear that I'm not a python programmer (I was just called to put
out the flames in this project because no one else would and I was brave enough
to say yes).
I have the following problem here. I have to write a method that connects to an
existing localhost MySQL database (I'm using connector version 1.0.12) and then
does pretty basic stuff. The parameters are sent by a GTK-written GUI (I didn't
write that interface). So I wrote my method like this:
--PYTHON CODE
def compMySQL(self, user, database, password, db_level, table_level,
column_level):
sql_page_textview = self.mainTree.get_widget('sql_text_view')
sql_page_textview.modify_font(pango.FontDescription(courier 10))
sql_page_buffer = sql_page_textview.get_buffer()
#Gonna try connecting to DB
try:
print(Calling conn with U:{0} P:{1}
DB:{2}.format(user,password,database))
cnxOMC = mysql.connector.connect(user, password,'localhost',database)
except:
print Error: Database connection failed. User name or Database name may
be wrong
return
#More code ...
END OF PYTHON CODE-
But when I run my code I get this:
-CONSOLE OUTPUT
Calling conn with U:root P:PK17LP12r DB:TESTERS
Error: Database connection failed. User name or Database name may be wrong
---END OF COLSOLE OUTPUT---
And I don't know why, since the arguments sent are the same arguments that get
printed (telling me that the GUI the other guy coded works fine) and they are
valid login parameters. If I hardcode the login parameters directly insetad of
using the GUI everything goes ok and the functions executes properly; the
following code executes nice and smooth:
--PYTHON CODE-
def compMySQL(self, user, database, password, db_level, table_level,
column_level):
sql_page_textview = self.mainTree.get_widget('sql_text_view')
sql_page_textview.modify_font(pango.FontDescription(courier 10))
sql_page_buffer = sql_page_textview.get_buffer()
#Gonna try hardcoding
try:
#print(Calling conn with U:{0} P:{1}
DB:{2}.format(user,password,database))
cnxOMC = mysql.connector.connect(user=root,
password='PK17LP12r',host='localhost',database='TESTERS')
print 'No prob with conn'
except:
print Error: Database connection failed. User name or Database name may
be wrong
return
#more code ...
END OF PYTHON CODE--
Console output:

Any ideas guys? This one is killing me. I'm just learning Python but I imagine
the problem to be something very easy for a seasoned python developer so any
help would be strongly appreciated.

In the first example you're using positional arguments, whereas in the
second example you're using keyword arguments. Are you sure that the
positional arguments are in the correct order?
Try using keyword arguments in the first argument:
cnxOMC = mysql.connector.connect(user=user, password=password,
host='localhost', database=database)
It might also help if you print the repr of the arguments; that way
you'll be able to see the difference between, say, 0 and 0.
On another point, using a 'bare' except (except:) is virtually always
a *bad* idea. It'll catch _all_ exceptions, including NameError, which
could indicate a bug in your code. Catch only what you need to, only
what you're expecting and can handle.

Thanks, I really don't know the difference between positional and keyboard
arguments so I think I must do some python reading. I'm not really a python
programmer (I'm a C, assembly, Java and C# programmer). Anyway the code is now
working.
Thanks a lot to both of you.

There appear to be a few exceptions to this rule, i.e. a few standard library modules import ctypes.

Along with batteries included and we're all adults, I think Python needs
a pithy phrase summarizing how well thought out it is. That is to say, the
major design decisions were all carefully considered, and as a result things
that might appear to be problematic are actually not barriers in practice. My
suggestion for this phrase is Guido was here.
Designed.
You simply can't get a good clean design if you just let it grow by
itself, one feature at a time. You'll end up with something where you
can do the same sort of thing in three different ways, and they all
have slightly different names:
http://me.veekun.com/blog/2012/04/09/php-a-fractal-of-bad-design/#general
(Note, I'm not here to say that PHP is awful and Python is awesome
(they are, but I'm not here to say it). It's just that I can point to
a blog post that shows what I'm saying.)
Design is why, for instance, Python's builtin types all behave the
same way with regard to in-place mutator methods: they don't return
self. I personally happen to quite like the return self style, as it
allows code like this:
GTK2.MenuBar()
-add(GTK2.MenuItem(_File)-set_submenu(GTK2.Menu()
-add(menuitem(_New Tab,addtab)-add_accelerator(...))
-add(menuitem(Close tab,closetab)-add_accelerator(...))
... etc ...
))
-add(GTK2.MenuItem(_Options)-set_submenu(GTK2.Menu()
-add(menuitem(_Font,fontdlg))
... etc ...
))
... etc ...
It's a single expression (this is from Pike, semantically similar to
Python) that creates and sets up the whole menu bar. Most of Pike's
object methods will return this (aka self) if it's believed to be of
use. The Python equivalent, since the .add() method on GTK objects
returns None, is a pile of code with temporary names. But that's a
smallish point of utility against a large point of consistency;
newbies can trust that a line like:
lst = lst.sort()
will trip them up immediately (since lst is now None), rather than
surprise them later when they try to make a sorted copy of the list:
sorted_lst = lst.sort()
which, if list.sort returned self, would leave you with sorted_lst is
lst, almost certainly not what the programmer intended.
Oh, and the use of exceptions everywhere is a sign of design, too.
Something went wrong that means you can't return a plausible value?
Raise.
json.loads({)
ValueError: Expecting object: line 1 column 0 (char 0)
pickle.loads(b\x80)
EOFError
Etcetera. PHP borrows from C in having piles and piles of was there
an error functions; there's no consistency in naming, nor (in many
cases) in the return values. Pike generally raises exceptions, but I/O
failure usually results in a zero return and the file object's errno
attribute set; but at least they're consistent error codes.
This is design. Python has a king (Guido). It wasn't built by a
committee. Maybe you won't like some aspect of Python's design, but it
has one, it's not just sloppily slapped together.

While I agree with your general thrust, I don't think it's quite so
simple. Perl has a king, Larry Wall, but his design is more or less
throw everything into the pot, it'll be fine and consequently Perl is,
well, *weird*, with some pretty poor^W strange design decisions.
- Subroutines don't have signatures, you have to parse arguments
yourself by popping values off the magic variable @_ .
- More special variables than you can shake a stick at: @_ $_ $a $b @ARGV
$ ${^ENCODING} $. $| $= $$ $^O $^S @F and many, many more.
- Context sensitivity: these two lines do very different things:
$foo = @bar
@foo = @bar
and so do these two:
my($foo) = `bar`
my $foo = `bar`
- Sigils. Sigils everywhere.
- Separate namespaces for scalars, arrays, hashes, filehandles,
and subroutines (did I miss anything?), co-existing in the same
scope, all the better for writing code like this:
$bar = foo($foo, $foo[1], $foo{1})
If you think that all three references to $foo refer to the same
variable, you would be wrong.
- Two scoping systems (dynamic and lexical) which don't cooperate.
- Strangers to Perl might think that the way to create a local variable
is to define it as local:
local $foo;
but you'd be wrong. local does something completely different. To
create a local variable, use my $foo instead.

Likewise Rasmus Lerdorf, king of PHP (at least initially), but he had no
idea what he was doing:
I had no intention of writing a language. I didn't have a clue how to
write a language. I didn't want to write a language, Lerdorf explained.
I just wanted to solve a problem of churning out Web applications very,
very fast.

My apologies, I wasn't exactly clear. Having a king doesn't in any way guarantee a clean design... Likewise Rasmus Lerdorf, king of PHP (at least initially), but he had no idea what he was doing: I had no intention of writing a language. I didn't have a clue how to write a language. I didn't want to write a language, Lerdorf explained. I just wanted to solve a problem of churning out Web applications very, very fast. ... yeah, what he said; but having no king pretty much condemns a project to design-by-committee. Python has a king and a clear design. In any case, we're broadly in agreement here. It's design that makes Python good. That's why the PEP system and the interminable bike-shedding on python-dev is so important... and why, at the end of the day, the PEP's acceptance comes down to one person (Guido or a BDFL-Delegate).

Raymond Hettinger added the comment: Almost all of these make the docs worse and should not be applied. The purpose of the equivalent code is simply to make the documentation clearer, not to show all the ways it could have been done.

Stefan Krah added the comment: Using the microbenchmark I get (standard version): ./python -m timeit import sys; modname='operator' __import__(modname); del sys.modules[modname] 1000 loops, best of 3: 460 usec per loop Victor's version: ./python -m timeit import sys; modname='operator' __import__(modname); del sys.modules[modname] 1000 loops, best of 3: 355 usec per loop Importing _operator directly: ./python -m timeit import sys; modname='_operator' __import__(modname); del sys.modules[modname] 1 loops, best of 3: 35.7 usec per loop Extrapolating from what I did with decimal, I guess a _pyoperator version could get down to something like 70 usec. -- nosy: +skrah ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19229 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue19232] Speed up _decimal import

[issue18804] pythorun.c: is_valid_fd() should not duplicate the file descriptor
STINNER Victor added the comment: Did you encounter this in real life? Well, my initial concern was that dup() creates an inheritable file descriptor. It is unlikely that fork() occurs while is_valid_fd() is called, because is_valid_fd() is only called early during Python initialization. Replacing dup() with _Py_dup() would be overkill: _Py_dup() releases the GIL and raises an exception, which is not needed here. I'm closing the issue. I will reopen it if I find a simple solution to this non-issue :-) -- resolution: - invalid status: open - closed ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18804 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue19108] Benchmark runner tries to execute external Python command and fails on error reporting
Stefan Behnel added the comment: Here's a patch that replaces the current simplistic Python executable command config with a dedicated PythonRuntime config class. That makes it easy to properly pass around the program specific configuration. Part of that is the Python executable path, the Python version, the specific command line arguments and the relative benchmark library path. The patch also adds a --pyversions command line option to avoid calling the executable for figuring out the Python versions, as discussed. -- keywords: +patch Added file: http://bugs.python.org/file32062/add_pyversions_option_and_refactor_runtime_config.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19108 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
