I'm pretty sure this somewhat horrifying code does it, but is probably
an example of what not to do:

>>> escapeseq = '비'
>>> uescape = ("\\u%x" % int(escapeseq[2:-1])).decode("unicode_escape")
>>> uescape
u'\ube44'
>>> print uescape
비
(I don't seem to have the font for it, but I think that's right - my
terminal font seems to show it correctly).

I just get the decimal value of the escape, format it as a Python
unicode hex escape sequence, and tell Python to interpret it as an
escaped unicode string.

>>> entities = ['비', '행', '기', '로',
'보', '낼', '거', '에', '요', '내',
'면', '금', '이', '얼', '마', '지',
'잠']
>>> def unescape(escapeseq):
... return ("\\u%x" % int(escapeseq[2:-1])).decode("unicode_escape")
...
>>> print ' '.join([ unescape(x) for x in entities ])

It is. Sorry. I initially misread Kent Johnson's post. He just used

Theoretically, if I messed around with the 2.4 project until I got it to

My initial answer was no, as 2.4 .pyd extensions are build with VC 7.1,
and that uses a different CRT. However, as David Fraser points out,
"2.4 .pyd extensions" doesn't really say much what compiler has been
used, so if you use VC6 to build the extensions, it will work fine.
Also, I'm not sure what "mess around with the 2.4 project" means. Are
you talking about the project and solution files in PCbuild? Don't
mess with them, use PC/VC6 instead.

Change your script's name from datetime.py to something else. Otherwise the

You are importing your script, not the library module here.

Just rename that file to mydatetime.py or something, and you're fine.

GetFirstChild() changed from taking 2 arguments in wxPython 2.4 to
(the more sensible) 1 in wxPython 2.5. Clearly wxProject hasn't

Actually, in a sense, if you put up a SVN repository under Apache, the 
repository is available "via the Web" just as the OP requires.  He'll 
have to specify further, but I'm not so sure this is a requirement to be 
able to edit via a browser over the web, or just have the repository on 
the web somewhere that multiple people can access it.

But SVN will work pretty well, I think, for what you're doing.  
Especially if the authors are editing different sections of the file.  
If two (or more) authors try to edit the same section of file, the first 
one to commit the change will "win" and any subsequent commits will not 
be able to commit the change until the resolve the conflict.

One way:

 >>> mylist = [0, 1, 1, 1, 1, 5, 6, 7, 8, 1, 10]
 >>> [i for i,v in enumerate(mylist) if v==1]
 [1, 2, 3, 4, 9]

Cool idea.  Convert ip matches to fixed patterns before matching a fixed
regex. The leftovers like shaw cable (which has the MAC address of the
cable modem instead of the IP) can still be handled with regex patterns.

I had an idea last night to compile 254 regexes, one for each possible
last IP byte - but I think your idea is better.

Mitja suggested a socring system reminiscent of SpamAssassin.

That gives me a few things to try.

style query: function attributes for return codes?

[george young]

[python 2.3.3, x86 linux]
I recently found myself writing something like:

def get_connection():
if tcp_conn():
if server_allows_conn():
return 'good_conn'
else:
return 'bad_auth'
else:
return 'no_server'


cn = get_connection()
if cn == 'good_con': ...


This is obviously just evil, since a misspelling in the string
return is treacherous.  I'm considering function attributes:

def get_connection():
if tcp_conn():
if server_allows_conn():
return get_connection.GOOD
else:
return get_connection.BAD_AUTH
else:
return get_connection.NO_SERVER
get_connection.GOOD = 1
get_connection.BAD_AUTH = 2
get_connection.NO_SERVER = 3


If I put this function in it's own module, the solution is obvious:

GOOD_CONN = 1
def get_connection():
...
return GOOD_CONN   


But if this is a small utility function that belongs inside a
larger module/class, I would like to have it's return values
closely associated with the function, not just another value in
the parent class.

Is anybody using function attributes like this?
Is this good python style?

MySQLdb blob and binary data

[Rune Hansen]

I'm storing gzipped data in a MySQL blob field. I can fetch the blob and 
"wb" write the data to a file. It becomes a file containg gz data.

I can't take the same data and do anything sensible with it in python - 
like say zlib.decompress(data).

How can I convert the binary data from the blob field to the gzipped 
string it was stored as (java stores the string, Pickle is not an option)?

Tibia 0.1 DOM-based website editor

[Robert Brewer]

Cross-posted here to encourage comments/discussion. I know there's a big
feature or two I'm missing out on ;) Suggestions welcome.

Tibia is an in-browser editor for web pages. It allows you to quickly
and easily modify the content of your web pages. It allows you to
directly view, edit, and save files on your webserver. It also allows
you to upload files from your local filesystem to your webserver, and
then edit those documents. It also allows you to grab web pages from
other websites and save them on your server, and then edit _those_.

Stick the single tibia.tba file on your webserver (assuming Python is
installed) and you're off and editing files in the same folder or below.
Admins can edit any element; non-admins can edit any element for which
admins give them permission.

You should probably have IE6 or Firefox; IE has limitations. If you want
to test it with another recent browser (it's all DOM-based), feel free
and let me know what breaks: [EMAIL PROTECTED] Ditto for other
webserver/OS/Python versions. You can also fill out complete bug reports
or feature requests at http://www.casadeamor.com/FogBugz.

Tibia is public domain.

thread/queue bug

[phil]

I have a very strange bug.  A thread in a .pyc stops dead.
This program has many threads and queues and has worked
great for months.
One thread listens for UDP messages from other programs,
and puts the messages in listenq.
Procmsgs gets from listenq and for a certain kind of
message creates another mq = Queue(0).
I don't wish to distribute the source to pnetx.py
so I have a short program pnet.py import it, that is
pnetx.pyc.
Then the procmsgs thread dies at the Queue statement.
But if I run pnetx.py as the main program, all works fine.
So if pnetx.py or .pyc is imported this thread dies. ???
I've tried this with 2.3.3 and 2.3.4.  Anyone?

Although in most cases this is probably okay, you're not guaranteed that 
the name of your function will stay the same, so there are some hazards 
in this style:

>>> def f(x):
... return f.y * x
...
>>> f.y = 100
>>> f(2)
200
>>> g, f = f, None
>>> g(2)
Traceback (most recent call last):
  File "", line 1, in ?
  File "", line 2, in f
AttributeError: 'NoneType' object has no attribute 'y'
One option is to turn your function into a class:
class get_connection(object):
GOOD = 1
BAD_AUTH = 2
NO_SERVER = 3
def __new__(cls):
if tcp_conn():
if server_allows_conn():
return cls.GOOD
else:
return cls.BAD_AUTH
else:
return cls.NO_SERVER
This is a little sneaky here -- because you only need shared state 
between all instances of get_connection, you don't actually ever need to 
create an instance.  So I've overridden __new__ to return the result of 
the function instead.  This allows you to call the function just like 
you would have before.  I haven't tested the code above, but here's a 
simpler example that works:

>>> class look_ma_no_function(object):
... X = 42
... def __new__(cls):
... return cls.X
...
>>> look_ma_no_function()
42
If you need to do this with a function that takes more parameters, you 
can just add them to the __new__ declaration:

>>> class look_ma_no_function(object):
... X = 42
... def __new__(cls, s):
... return cls.X / float(len(s))
...
>>> look_ma_no_function('answer to life the universe and everything')
1.0
Despite the fact that this particular use seems a little sneaky to me, I 
do usually end up turning most functions that seem to need attributes 
into classes (usually with a __call__ method defined).

Hmm, thanks for the suggestions.  One more quick question.  Is it even

"break Class.f" without the condition.  I don't think the documentation for

Only for old-style classes, though. If you inherit from object or 
another builtin, that recipe fails.

Could you explain, please? I thought __getattr__ worked the same with 
new- and old-style classes?
Looking at the recipe more closely, I believe you are correct - the behaviour 
shouldn't change much between old and new style classes (the main difference 
being that the new-style version is affected by descriptors, along with the 
other things which may prevent __getattr__ from being invoked in either sort of 
class).

However, all that means is that the recipe wouldn't help the OP even with a 
classic class. In neither case will implicit invocation find the correct methods 
on the object we are delegating to.

The trick has to do with the way special values are often looked up by the 
Python interpreter.

Every class object contains entries that correspond to all the magic methods 
that Python knows about (in CPython, these are function pointers inside a C 
structure, FWIW).

When looking for a special method, the interpreter may simply check the relevant 
entry in the class object directly - if it's empty, it assumes the magic method 
is not defined and continues on that basis.

A simple example:
  class foo:
def __init__(self):
  print "Hi there!"
When a class object is built from this definition, the "def __init__" line 
actually means two things:
  1. Declare a standard Python function called '__init__' in the class 'foo'
  2. Populate the appropriate magic method entry in class 'foo'

When overriding __getattribute__ only, step 2 never happens for most of the 
magic methods, so, as far as the interpreter is concerned, the class may provide 
access to an attribute called "__add__" (via delegation), but it does NOT 
provide the magic function "__add__".

In order to have the delegation work as expected, Python has to be told which 
magic method entries should be populated (there is no sensible way for Python to 
guess which methods you intend to delegate - delegating __init__ or 
__getattribute__ is almost certainly insane, but what about methods like 
__call__ or __getattr__? __repr__ and __str__ pose interesting questions, too)

A nice way to do this is with a custom metaclass (thanks to Bengt for inspiring 
this design - note that his version automatically delegates everything when you 
call wrapit, but you have to call wrapit for each class you want to wrap, 
whereas in this one you spell out in your wrapper class which methods are 
delegated, but that class can then wrap just about anything).

wrapper.py:
=
# A descriptor for looking up the item
class LookupDescr(object):
def __init__(self, name):
self._name = name

Stick the single tibia.tba file on your webserver (assuming Python is
installed) and you're off and editing files in the same folder or below.
Admins can edit any element; non-admins can edit any element for which
admins give them permission.

I don't have a lot of experience with CGI, though, so any help would be

You can pass any file-like object to GzipFile class:

Right. 

I usually like to look at such problems from the angle of 
what is most convenient for the *caller* side? 

And having to adress function attributes does
not seem convenient.  I'd probably like to do from 
the caller side something like: 

conn = get_connection() 
if conn.good: 
... 
elif conn.badauth: 
... 
elif conn.noserver: 
... 

which allows you to freely choose and hide your actual
implementation at the "called" side. Example: 

class Connection(object): 
def __init__(self, **kw): 
for name in kw: 
assert name in ('good', 'badauth', 'noserver'), name 
setattr(self, name, kw[name]) 

def get_connection():
if tcp_conn():
if server_allows_conn():
return Connection(good=True) 
else:
return Connection(badauth=True) 
else:
return Connection(noserver=True) 
 
And btw, the view of "what do i want at the caller side?" 
is natural if you do test-driven development and actually 
first write your tests.  Another reason why testing is 
a good thing :-)

I assume you're using the demo? My copy of Firefox has an error browser

Compiling Python 2.4 extensions with free VC++ Toolkit

[Burns]

Hi all,
I've been wondering if there's anything on the drawing board about 
patching distutils/msvccompiler.py so that it can compile Python 
extensions using the free Visual C++ toolkit instead of the entire 
Visual C++ development environment.

I know it's possible, because I was able to compile and install PyCrypto 
2.0 for Python 2.4 today.  I did this by commenting out the part of 
msvccompiler that checks for VS library paths and manually adding them 
to my LIB environment variable.

I looked through the CVS and couldn't find anything about this, although 
 msvccompiler.py has been patched to give a better error message about 
requiring the .NET framework if you have don't have it installed.

Your thoughts?

You need to use some sort of authentication with Tibia, or it can't tell
who's an admin and who's not. The demo uses Basic Auth. Add something like
the following to your .conf for the tibia folder:

AuthType Basic
AuthName "Tibia"
AuthUserFile D:\htdocs\tibia\passwords
Require valid-user

...and then use htpasswd to create the passwords file.

I will look into ways to use Tibia without auth, for intranets, perhaps.
Thanks!

None, other than to note that if you and/or others were able to
solve this and make it "easy" for those less VC++-savvy, you
might significantly decrease the bar for those of us who have
not been able to get into hacking on the core of Python because
of being stuck in the MS world yet not willing to shell out more

This has the benefit that if your user wants different return values 
they can specify them, but the disadvantage that someone improperly

Another disadvantage is that one must compare the return value by value 
and not by name. That is, I cannot do something like this:

code = get_connection()
if code == NO_SERVER:

Good point.  The class-type implementation does allow you to do this:

[Newby] question about modules

[Jon]

Hi,

The following four lines of code:

import sys, os, re
sentence = raw_input("Enter a sentence:  ")
capwords (sentence)
print sentence

gives me the following error:  NameError: name 'capwords' is not defined

As far as I can tell from the online docs, "capwords" should be defined in
the built-in "regex" module.  Why is it telling me that capwords is not
defined?

I am completely new to Python so my apologies for such a basic question!

Thanks,

Remember, in Python, a regex (well, regex source) is just a string, so
you can do any string manipulation you want to with it, and python has
a lot of tools for doing that.

One cool way to make regexes more readable, that i've seen proposed,
is to break them into components like the following (please pardon my
lack of regex skill, these may not actually work , but you get the idea):

normalword  = r'[A-Za-z][a-z]*'
digit   = r'\d'
capletter   = r'[A-Z]'

codeblock = normalword + 4*digit + '-' + 3*digit + 2*capletter + '\s+' + 
normalword

or somesuch (the 'r' BTW stands for 'raw', not 'regex', and while it's the most
obvious use, there's nothing particularly special about r strings, except for
not trying to process escape characters, thus avoiding the "pile of toothpicks"
problem).

And hey, you could probably use a regex to modify a regex, if you were
really twisted. ;-)

Sorry.  I really shouldn't have said that. Somebody's going to do it now. :-P

Cheers,
Terry

I have a very strange bug.  A thread in a .pyc stops dead.
This program has many threads and queues and has worked

One thread listens for UDP messages from other programs,

Procmsgs gets from listenq and for a certain kind of
message creates another mq = Queue(0).
I don't wish to distribute the source to pnetx.py
so I have a short program pnet.py import it, that is
pnetx.pyc.
Then the procmsgs thread dies at the Queue statement.
But if I run pnetx.py as the main program, all works fine.
So if pnetx.py or .pyc is imported this thread dies. ???
I've tried this with 2.3.3 and 2.3.4.  Anyone?
A few random thoughts:
1. You haven't provided nearly enough info for anyone
to be able to help much, I suspect.
2. Threading problems can be incredibly complex and race
conditions are frequently next to impossible to troubleshoot,
let alone reproduce reliably.
3. Distributing a .pyc does very little to prevent someone
from getting your source, since it is possible to "decompile"
.pyc files into something fairly closely resembling the
original source.
4. The fact that you have a .pyc file instead of a .py
file very likely has *nothing* to do with any threading
problem you are facing, so I suggest you get past that mental
block and look elsewhere.
5. Sorry I can't be more help.  You don't give anyone much
to go on.  All that stuff about "Queue(0)" and "listenq"
is pretty much meaningless to us, you know...

I've run into this a couple of times. Often, setting the default ASP
language to Python is the trick.

Well, that could be a feature, depending on what your use case is.
Or you could make a method for adding methods, I suppose.
A perfectly transparent wrap of obj would be to do nothing ;-)
What do you actually want to do?

What self are you referring to? Anyway, inst is None when you access
a descriptor instance as a class attribute, e.g., MyClass.desc as opposed
to as an attribute of an instance of that class, e.g., MyClass().desc.
Even __dict__ is actually itself a descriptor. Try
type(obj).__dict__['__dict__'].__get__ (on a new style obj instance).
vs type(obj).__dict__.__get__ which doesn't work.

This is to create a bound method that's bound to the thing, not to the
wrapper object. I guess this could be done at wrapping time instead.
I was just hacking down the path of least resistance ;-)

Sorry, this was to eliminate some problems I had along the way. But __new__
and __init__ have to be kept out of the Wrapper class or they will be
invoked when Wrapper() is done to create the wrapped object.

I have hacked something better, not using def __metaclass__, which isn't
necessary. (I just prepare a cdict similarly, and then use that in
 
Wrapper = type('Wrapped_'+type(thing).__name__, (object,), cdict)

plus playing games to avoid the wrong __init__ and __new__ etc.) 

Also, I just remembered an idea that someone had used to limit
methods in an attempt at security by assigning obj.__class__ with a
compatible class. So that might be an avenue too. Maybe a wrapper could
be a subclass of type(obj), and then just copy method function references
to the wrapper class dict? I'll have to explore that another time...

What is your actual use case? ;-)

Even if you were, there is certainly no need to apologize.  In
hindsight, my response seems rather naive; as naive perhaps as the
students in my freshman year undergrad C class who having grown up on
Turbo pascal would add to their programs:

#define BEGIN {
#define END {

because it "looked right."

There is actually a workaround. You're using Simple MAPI which has a 
nice easy interface. The confirmation dialogs are only for Simple MAPI. 
Using Extended MAPI can work around the problem but its a lot more tricky.
See the initial discussion here:

This code has now been included in pywin32 somehow but I can't remember

Re: [Newby] question about modules

Is it in "regex" or "re"? If in "re" then:

If in "regex", then:

regex.capwords(sentence)


You can also do

from re import *

then you will not have to prefix. But careful not to clutter your namespace.

Hi Jeff,

That makes sense -- thanks.  However now when I use "re.capwords (sentence)"
I get a different error message:

Each of the other two suggested implimentations produce a similar error

and I bet it would take longer to understand it.
If my explanation was insufficient, I'm sorry.
ALSO, you did not respond to my email, so I didn't know how to reply.
There is nothing on the archives page which gives me a clue as to

Hmm... are you looking instead for "capwords" from the string module?

Note that there are a few subtle differences between string.capwords and 
str.title -- string.capwords capitalizes only at whitespace boundaries 
(and replaces runs of whitespace with spaces), while str.title 
capitalizes at alphanumeric boundaries.

Clarification of two concepts (or maybe one?)

[Eddie Parker]

Sorry, I’ve tried to search the web on this,
but I’m still a little fuzzy. I was hoping a quick e-mail might clear
this up.


What I’m looking for, is a way to turn a python ‘application’,
into a ‘stand-alone’ application. i.e., you don’t need the
Python interpreter, libraries, etc, installed on your hard drive. (I’m OK
with .py files existing – I just don’t want to have to bother the
user to install more then just my app). 

 

One alternative is to embed the Python interpreter in
a C++ app, and then just call the entry point... But I’m curious if there’s
a better way?

 

On the unrelated (or maybe related) concept, the words
“python freezing” keeps buzzing around my subconscious. I’m
not sure if this item can help me in any such way, but I can’t find any
good articles on what this phenomenon *is*.
Can anyone point me to a definitive web page that describe this, or indicate if
it *is* in fact what I’m
looking for? (I’m probably way off base on this one).

 

Anyhow, your help is most appreciated! Thank you!

application,
but I realized it doesn't work on NEC V25 CPU (8086/8088 compatible
CPU developed by NEC).

I was involved in to our school computer "research" :) and we need
this piece of code to reach our goal.

We have to demonstrate the power of the free software (mainly its

Can you please search your archives or route me somewhere?

you cannot run Python without a Python interpreter -- but you can ship the

you can use bundling tools to reduce the number of files to a minimum:

Re: Wrapper objects

[redhog]

Ah, thanks. I didn't think of the possibility of creating a list of
methods that needed wrapping, and wrapping them uppon creation of the
wrapper object. Mainly I think, becaus it seems to me as such an uggly
workaround for a misdesign in Python. Also, if the wrapped object gets
some extra methods/callable member variables added "after the fact",
those will not get wrapped (this is however not a common thing to
happen, it just annoys me that it won't work).

As to what I want to use this for, I today have a huge program in which
several objects are wrapped up with comments (made up by some DOMish
structre) which are displayed to the user at various times. For
example, a list of users may be represented as as comment "List of
users" and a python list of elements, each being a user id (represented
as an integer), with a comment being the username. This means the list
is usable both for user-output and for machine-handling. Hm, this
wasn't prolly such a good example, but hopefully, it shows enought of
the idea...

Todya, the comment-value-pair is an ordinary object with two member
variables, and there are two functions, getComment and getValue, which
extracts a comment if its argument is such an object, or None
otherwise, and the wrapped value if its argument is such an object, and
the argument itself otherwize, respectively.

This means my code is literally filled with calls to getValue(), which
I would like to be able to remove by making the comment-value pair more
transparent.

Anyway, I do have some questions about your implementation:

If "if inst is None: return self" to protect for infinite recursion
when looking up self.__dict__?

What is the reason to give func to the MethodDesc property object, why
does its __get__ method have to do

if func: return func.__get__(self.thing, type(self.thing))

?

What is the reason to neither wrap, nor just copy, any of __getattr__,
__getattribute__, __setattr__, '__new__' or '__init__'? Especially
__getattr__, __getattribute__ and __setattr__ seems to need at least
some type of wrapping (but perheaps some special one)?

as an integer), with a comment being the username. This means the list
is usable both for user-output and for machine-handling. Hm, this
wasn't prolly such a good example, but hopefully, it shows enought of
the idea...

Tody, the comment-value-pair is an ordinary object with two member
variables, and there are two functions, getComment and getValue, which
extracts a comment if its argument is such an object, or None
otherwise, and the wrapped value if its argument is such an object, and
the argument itself otherwize, respectively.

This means my code is literally filled with calls to getValue(), which
I would like to be able to remove by making the comment-value pair more
transparent.

The wrapper objects needs to work as dictionary keys, to support
printing, concatenation/addition, getitem/setitem and such things...

Does it have to be Python?  There are other languages that
are arguably as portable, and certainly more compact.  Lua,
for example, has been ported to quite small devices.  See
http://www.lua.org/ for more on that, but note there are
other options as well.  Python's not the only "free portable
software" around, though it's the best in many ways.

vincent has the solution (you need to specify them in MANIFEST.in),
but I'll add my 2 cents.

depends = [...] is used in building (it's like dependencies in make).
If one of those files change, distutils will rebuild the extension.
But that's all distutils does with it. It's braindead including stuff
in the source distribution, including depends, data files, and other
stuff you'd think it would do. When in doubt, add it to MANIFEST.in.

You want a wiki engine.  There are many to choose from, some of which 
have all the features you want.
See for example Atlassian Confluence.  We are using it to create 
documentation for boo ( http://boo.codehaus.org ).  This page for 
example has child pages and you can export pages to html, pdf, or xml.
http://docs.codehaus.org/display/BOO/Recipes
http://docs.codehaus.org/spaces/exportspace.action?key=BOO

I think the PHP/MySQL-based Tiki wiki has similar features, too.

Did you also think about ISPs that use such a PTR record for both dynamic

ANNOUNCE: PyPHP, Python programming using the PHP web framework

[Antony Lesuisse]

PyPHP the python php bridge
===

Download it at http://lesuisse.net/pyphp-0.1.tgz

WARNING this is experimental !

Summary:


PyPHP enables Python programming in the PHP web framework.
PyPHP is not yet another Python Web framework, it is the PHP web framework made
available to Python programmers.

With PyPHP you get the best of both Python and PHP world:
- The power, cleanness and robustness of the Python language
- The much used, developped and maintained PHP framework

The most useful PHP framework features you get access to are:
- Session management (using pickle you are be able to store your python objects
  in the PHP sessions)
- Persistent database connections
- HTTP authentification
- Ouput buffering and header/cookie management

While most python programmers would favor the Python Standard Library to the
PHP functions library, PyPHP allows PHP programmers to use the PHP functions
from their Python code and brings new features to the Python programmers.


Quickstart:
---

Hello world in pyphp, hello.php:

---

from pyphp import php

print "Hello World"
---

Accessing php functions, test.php:

---

# vim:syntax=python:
from pyphp import php

php.header("Content-Type: text/plain")
print "Hello from python\n"
print php.explode("/","/etc/passwd")
php.eval("print_r($_SERVER);")

Granted.

Of course, when I said evil, I didn't mean evil, I meant Evil(tm).  I
suspect Nick meant so as well.

Personally, I just think __import__(__name__) is a bit more honest than
globals() for a simple reason.

What are you doing?  You're changing module attributes.  Well, here's
the module object.  You're using setattr on the module object to set
module attributes.

What are you doing?  You're changing module attributes.  Well, here's
the module's dict.  You're using dictionary access on the modules dict
to set modules attributes.

It's a bit more honest to set module attributes using setattr than dict
access, I would say.  That's why I prefer it.  I admit, it's pretty
weak.  (But then again, so is __import__ being uncommon. :)  It's not a
big deal which you choose, as you say.  Although I don't use globals()
in this way, I do modify object dicts to get the effect of changing
object attributes from time to time (mostly to take advantage of dict
methods, which I could see being a reason to use globals() as well).
