Since you know the content of what the sql code is, why not just build
the sql file(s) needed and store them so that in case of a burp you can
just execute the code file. If you don't know the exact sql code, dump
it to a file as the statements are constructed... The only problem you
would run into in this scenario is duplicate data, which is also easily
solvable by using transaction-level commits to the db.

Re: pythonic way

[jack]

Sometimes, I need to alter the element as traverse a list like this 
(it's a sample):

c = range(10)
i = 0
for ele in c:
# do something
# branch:
c[i] = # value
i += 1

How to be pythonic？

As everyone else has said, it's perfectly pythonic once you stick the
colon on the end. You might find it more instantly readable with some
extra parentheses:

 if (0 < ix < 10) and (0 < iy < 10):
 # do something

... but that's really just down to taste.

Re: pythonic way

thanks,but I don't think enumerate() is my want
Have some ways to operate the reference of element,not a copy when I 
tried to traverse a list?


I'm so sorry about my poor English, hope you don't mind it.

That's not much of a clue. Do you mean you get an exception? If so,
paste it into a message, the full traceback. Or you mean it returns the
wrong data? Or it crashes your OS?

My first guess would be that those slashes are causing syntax errors.
But if that's a bug in your OS's copy/paste, then I'd say you have
indentation problems. Or maybe these are not just functions, but methods
inside a class. And in that case, I might guess that you're missing the
self argument, and therefore getting an exception of wrong number of
arguments.

Why __slots__ slows down attribute access?

[Jack]

People have illusion that it is faster to visit the attribute defined
by __slots__ .
http://groups.google.com/group/comp.lang.python/msg/c4e413c3d86d80be

That is wrong. The following tests show it is slower.
__slots__ are implemented at the class level by creating descriptors
(Implementing Descriptors) for each variable name. It makes a little
bit slower.

So __slots__ just saves memory space by preventing creation of
__dict__ and __weakref__ on each instance, while sacrifice performance
and inheritance flexibility.

Zope - Restrict Acquisition Question

[Jack]

I have the following requirement for Zope:
I need to use Zope as a web cloning tool.

The directory structure is as follows:
->>Core Folder
->>Client 1
->>Client 2
...
->>Client n

1] Client 1 and Client 2 need to acquire from the Core Folder.
2] Client 2 must not acquire from Client 1.
3] Client 1 must not acquire from Client 2.

Note: I know that creating a Zope object named Client 2 and putting it
into Client 1's folder will work but there will be about 50+ clients.
So that would require 50+ objects in each client folder.

There's got to be a better way ... Any Ideas?

Thanks!

Hi, Guys!

progressBar and a Label, the next page named 'resultsPage' shows 
results(some Labels).


When the window showed progressPage, my code that updates progressBar 
was well, but the updating resultsPage's labels signals seems ignored 
by main thread.(I guess, because I added some prints in the slot, it 
wasn't printed)


the code like this:

 1. class worker(QtCore.QThread):
 2. sig_jump_finish_page = QtCore.pyqtSignal()
 3. sig_set_label_text = QtCore.pyqtSignal(str, str)
 4. sig_set_progress_value = QtCore.pyqtSignal(int)
5.

 6. for dirpath, dirnames, filenames in os.walk(self.root):
 7. for filename in filenames:
 8. self.sig_set_label_text.emit('current', self.current()) # work well
 9. # so something
10.

11. #self.dialog.set_found(str(self.found())) # work well
12. #self.dialog.set_all(str(self.total())) # work well
13. self.sig_set_label_text.emit('found', str(self.found())) # :(
14. self.sig_set_label_text.emit('all', str(self.total())) # :(
15.

16. self.sig_jump_finish_page.emit()


So I have to update UI directly in the thread(comments Line 11-12 
shows), it looks work well.


I found the difference between line 8 and line 13-14 is line 8 
manipulates current page -progressPage, line 13-14 manipulates next 
page -resultsPage.


Is some wrongs in there?






Have a look at my comments:

class worker(QtCore.QThread):
sig_jump_finish_page = QtCore.pyqtSignal()
sig_set_label_text = QtCore.pyqtSignal(str, str)
sig_set_progress_value = QtCore.pyqtSignal(int)


I'm sorry.
In run() function the code below
for dirpath, dirnames, filenames in os.walk(self.root): # What is 
'self' here ?
self is current object, isn't it? self.root is a path which the 
user will specify.

for filename in filenames:
self.sig_set_label_text.emit('current', self.current()) # where is 
'current' ?

# so something
self.current() is a getter, it just returns a member that shows the 
path of the current work.


#self.dialog.set_found(str(self.found())) # What is self, and dialog, 
and found ?

the main thread is a dialog object.
self.dialog was assigned the dialog object in the __init__ of 
worker class.
self.found() is a getter also, it returns the number of meeting the 
conditions. self.total() means like this.

#self.dialog.set_all(str(self.total())) # ...
self.sig_set_label_text.emit('found', str(self.found())) # again ?
self.sig_set_label_text.emit('all', str(self.total())) # etc

self.sig_jump_finish_page.emit()


dialog.set_all() and so on just sets the widget's text.

My English is poor, I hopeyou will excuse me.

How to delete a Python package

[Jack]

Installing a Python package is easy, most of time just
"Setup.py install" However, setup.py doesn't seem to support
an uninstall command. If I want to delete a package that I
do not use any more, should I just manually delete the
corresponding sub directory under Lib\site-packages?

Re: How to delete a Python package

I'd second Skip's point. Now that setup.py does install, and it knows what 
to
uninstall (because it copied the files in the first place) I think it's a 
good idea
to have "setup.py uninstall" support. :)

Python for Embedded Systems?

[Jack]

Is there a Python packaging that is specifically for
embedded systems? ie, very small and configurable so the
user gets to select what modules to install?

For Linux-based embedded systems in particular?

I'm thinking of running it on the Linksys's Linux-based open
source router WRT54G. It has 4MB flash and 16MB RAM. I think
another model has 16MB flash. Any possibilities of running
Python on these systems?

If Python is not the best candidate for embedded systems because
of the size, what (scripting) language would you recommend?

PHP may fit but I don't quite like the language. Anything else?
Loa is small but it does not seem to be powerful enough.

http://mail.python.org/mailman/listinfo/python-list

Re: Python for Embedded Systems?

[Jack]

Yes, I mean Lua, not Loa  :-p

Lua is a nice language. Like you said, it doesn't have many libraries
as Python does. Plus, it's still evolving and the libraries are changing.
I found a few functions not working last time I tried kepler libraries.
It's good for embedded systems though because of its small footprint.
Extensions implemented in C makes it possible that the installation size
doesn't blow up when new stuff is added, like in Python.

But I still like Python better for its power and for the style of the 
language
itself. And I was hoping to find a Python implementation that bears the
principles of Lua to make it suitable for embedded systems :)

>> PHP may fit but I don't quite like the language. Anything else?

Python SOAP and XML-RPC performance extremely low?

[Jack]

When I try TooFPy with the SOAP and XML-RPC sample client code
provided in TooFPy tutorials, a log entry shows up quickly on web server
log window, but it takes a long time (5 seconds or longer) for the client
to output a "Hello you." It seems like the web server is fast because the 
log
entry shows immieidately on web server console. But it takes Python XML/SOAP 
parser a long time to parse the extremely simple result. If so, wouldn't 
this
render Python SOAP and XMP-RPC implementation useless in real life?

Looking for a high performance web server written in Python, and supports CGI/FastCGI

[Jack]

Basically I am trying to find a high performance web server. Since
Python is installed on all of the servers, It'll be great if the web
server is written in Python as well. Otherwise, I will have to install
lighttpd or other web servers.

Then the largest issue with Python-based web servers is performance.
That's why I start to look into medusa or twisted-based servers. Twisted
seems too big and complicated for what I really want to do and the
original medusa web server only has very basic functionality.

And I'd like the web server to have CGI/FastCGI and possible SCGI
support for flexibility in application development. My applications
here are really internal testing or data provider tools. Am I asking
a lot? I think this is basic requirement for a web server these days :D

What it looks like is that, although there seem to be many Python http
servers available, there isn't really one that's simple, fast and
feature-rich (cgi/fcgi/scgi) - I guess I am asking too much ;-p
It seems that the only candidate that meetings the requirements but
"written in Python" is lighttpd.

Any recommendations?

Re: Looking for a high performance web server written in Python, and supports CGI/FastCGI

[Jack]

To be honest, I'm not sure what kind of performance I can get even
with medusa or twisted. I assume it won't be as fast as servers
written in C/C++ and use async sockets, but should be much better than
multi-processed or multi-threaded servers in written in Python.

Not sure if anyone else has an idea about medusa or twisted performance.
Any chance that it's close to Apache?

But even so, I guess I may still have to go with lighttpd for FastCGI/
CGI/SCGI support.

lighttpd is a great web server. I just didn't want to bother download the 
source,
configure, make and make install, and have a bunch of files installed into 
the system
(The binaries are mostly not the latest version.)  If a server can be set up 
with a few
python files, it sounds like a cleaner approach :)

lighttpd does have an option to make a monilithic build that has everything 
in
one file but somehow I couldn't make the scons-based build work. (Any tips?)

Re: Python SOAP and XML-RPC performance extremely low?

[Jack]

No, I'm not using any accelerator. The code is extremely simple (from 
toofpy):

# XML-RPC test
import xmlrpclib
srv = xmlrpclib.Server('http://localhost:4334/RPC2/greeting')
print srv.greeting('you', 5)

# SOAP test
import SOAPpy
srv = SOAPpy.SOAPProxy('http://localhost:4334/SOAP/greeting')
print srv.greeting('you', 5)

It really surprised me that they were so slow to execute.

If it is a Python web server, it would be nice to extend it by putting code
right into the web server. The performance should be better than FastCGI
because it removes the cost to send the requests/replies back and forth.

Re: Looking for a high performance web server written in Python, and supports CGI/FastCGI

[Jack]

I just did some testing between CherryPy's web server and lighttpd.
My test was very simple and I used ab.exe for this purpose.
CherryPy web server can serve about 140 simple request / second, while
lighttpd can handle around 400 concurrent requests.

Re: Looking for a high performance web server written in Python, and supports CGI/FastCGI

[Jack]

I wrote the last posting at late late night and I didn't know what I was
typing at that time ;-p

I didn't mean the test with CherryPy was not concurrent
connections, or the test with lighttpd was all concurrent
connections. I actually tried both concurrent (-c in ab command line)
and non-concurrent (without -c in ab command line) and I tried
the threading and threadpooling in CherryPy. The result did not
vary much.

This article http://www.cherrypy.org/wiki/CherryPySpeed says CherryPy
can process around 400-500 requests/second. It's set up is:

  Pentium M 1.6, 1G RAM, Windows XP2 laptop, test done with apache 2.0.41 
ab.

I have a slightly better hardware set up:

  Pentium M 1.7MHz, 1.5G RAM on Windows XP2 laptop, test done with Apache 
2.2 ab

However, I don't get even close. The best I get is around 140
requests/second. I'm using the same test script as the CherryPy test
with slight modification just to make it run. As a matter of fact,
the Cygwin build of lighttpd only gets around 430 requests/second for
a 2-byte static file. I disabled firewall and antivirus on the box when
tests were done. Any idea about the huge difference? It would be very
interesting if some CherryPy (or python) users can post their performance
benchmarks.

Re: Looking for a high performance web server written in Python, and supports CGI/FastCGI

[Jack]

You are right. Load test can be complicated because of the various patterns
of web applications and usages. The simple tests I mentioned and conducted 
just
give myself some idea about the performance. Given the same set up, some
numbers should be comparable and reveal some aspects on web servers'
performance. They are by no means formal load tests, but they are helpful to 
me :-)

I'm using CherryPy 2.2.1.
I just ran benchmark.py multiple times. The fastest it got is 195 req/sec, 
with
50 threads. Python was taking 50+% CPU when the test was running.

Re: Looking for a high performance web server written in Python, and supports CGI/FastCGI

[Jack]

Thanks Tim and Gerard for recommending karrigell.

I just checked it out. It is indeed a nice package. However, I didn't find 
it
easier to learn or use than CherryPy though. I read through CherryPy 
tutorials
and have got a good idea how to use it. I also read Karrigell docs. The way
Karrigell uses subpath behind CGI file name is a little strange to me. 
Nonetheless,
Karrigell looks very nice to me but I may start with CherryPy.

What's missing (according to my requirement/wishlist) is, as a web server, 
the
build-in web server does not handle CGI or FastCGI apps, making python
the only way to write apps...

python port for iPod

[jack]

Hi,
  Since May 2005 there is a port of python (v2.4.1) for Apple iPod.
  Porting was an 'easy' job, the only consideration was how you can
write with a
  iPod, ipodlinux [1] people did an interface called iPodRead that
allows you
  type into iPod scrolling left or right on the wheel. (This affects to
the file
  Parser/myreadline.c, line 47).
  Furthermore, is necessary run configure with options: --without-threads,
  --without-shared and --with-cxx and build it in a cross-compile
environment
  for ARM architecture.

  Running make the only problem was the function hypot (umm, like ipod
:)  in the math
  module (I don't remember the problem) but i had to change hypot(x,y) to
  sqrt(x*x+y*y).

  You can see the differences between python original and python ported
source
  in [2].

  First announce about the port can be found in [3].
  More info about this port, cool pictures and binaries & source code in

Large Amount of Data

[Jack]

I need to process large amount of data. The data structure fits well
in a dictionary but the amount is large - close to or more than the size
of physical memory. I wonder what will happen if I try to load the data
into a dictionary. Will Python use swap memory or will it fail?

Re: Large Amount of Data

[Jack]

I have tens of millions (could be more) of document in files. Each of them 
has other
properties in separate files. I need to check if they exist, update and 
merge properties, etc.
And this is not a one time job. Because of the quantity of the files, I 
think querying and
updating a database will take a long time...

Let's say, I want to do something a search engine needs to do in terms of 
the amount of
data to be processed on a server. I doubt any serious search engine would 
use a database
for indexing and searching. A hash table is what I need, not powerful 
queries.

Re: Large Amount of Data

[Jack]

I suppose I can but it won't be very efficient. I can have a smaller 
hashtable,
and process those that are in the hashtable and save the ones that are not
in the hash table for another round of processing. But chunked hashtable
won't work that well because you don't know if they exist in other chunks.
In order to do this, I'll need to have a rule to partition the data into 
chunks.
So this is more work in general.

John, thanks for your reply. I will then use the files as input to generate

What's the best way to iniatilize a function

[Jack]

I have a set of functions to wrap a library. For example,

mylib_init()
mylib_func()
mylib_exit()

or

handle = mylib_init()
mylib_func(handle)
mylib_exit(handle)

In order to call mylib_func(), mylib_init() has to be called once.
When it's done, or when program exits, mylib_exit() should
be called once to free resources.

I can list all three functions in a module and let the
application manage the init call and exit call. Or, better,
to have the wrapper function manage these calls. I'm currently
using a singleton class (see below.) It seems to work fine.

My questions here are:

1. every time I call the function:

MyLib().func()

part of the object creation code is called, at least to check if
there is an existing instance of the class, then return it. So it
may not be very efficient. Is there a better way?

2. what's the right way to call mylib_exit()? I put it in __del__(self)
but it is not being called in my simple test.


STATUS_UNINITIALIZED = 0
STATUS_INITIALIZED = 1
STATUS_ERROR = 2

class MyLib (object):
instance = None
status = STATUS_UNINITIALIZED

def __new__(cls, *args, **kargs):
if cls.instance is None:
cls.instance = object.__new__(cls, *args, **kargs)
return cls.instance

def __init__(self):
if self.status == STATUS_UNINITIALIZED:
mylib_init()
self.status = STATUS_INITIALIZED

def func(self):
return mylib_func()

def __del__(self):
mylib_exit()

Thanks Steven, for the reply. Very helpful. I've got a lot to learn in 
Python :)

Some questions:

Since it's a wrapper of a DLL or .so file, I actually need to call 
mylib_exit()
to do whatever cleanup the library needs to do.

I didn't call del explicitly. I'm expecting Python to call it when
the program exits. I put a logging line in __del__() but I never
see that line printed. It seems that __del__() is not being called
even when the program exits. Any idea why?

Parser Generator?

[Jack]

Hi all, I need to do syntax parsing of simple naturual languages,
for example, "weather of London" or "what is the time", simple
things like these, with Unicode support in the syntax.

In Java, there are JavaCC, Antlr, etc. I wonder what people use
in Python? Antlr also has Python support but I'm not sure how good
it is. Comments/hints are welcome.

Re: Parser Generator?

[Jack]

Thanks for all the replies!

SPARK looks promising. Its doc doesn't say if it handles unicode
(CJK in particular) encoding though.

Yapps also looks powerful: http://theory.stanford.edu/~amitp/yapps/

There's also PyGgy http://lava.net/~newsham/pyggy/

I may also give Antlr a try.

If anyone has experiences using any of the parser generators with CJK
languages, I'd be very interested in hearing that.

Re: Parser Generator?

[Jack]

Thanks for the suggestion. I understand that more work is needed for natural 
language
understanding. What I want to do is actually very simple - I pre-screen the 
user
typed text. If it's a simple syntax my code understands, like, Weather in 
London, I'll
redirect it to a weather site. Or, if it's "What is ... " I'll probably 
redirect it to wikipedia.
Otherwise, I'll throw it to a search engine. So, extremelyl simple stuff ...

unsigned integer?

[Jack]

This is a naive question:

"%u" % -3

I expect it to print 3. But it still print -3.

Also, if I have an int, I can convert it to unsigned int in C:
   int i = -3;
   int ui = (unsigned int)i;

Is there a way to do this in Python?

Custom Python Runtime

[Jack]

Since the full installation of Python (from either the standard installer or 
ActiveState installer) is too big for my intended use, I'd like to build a 
custom distribution of Python for Windows platform, omitting some lib files, 
such as audio, tk, printing, testing units, etc.

Is there a way to customize the Windows build? In my case, there is no need 
to build an installer. The best way is to have everything in a directory, as 
long as I know where to find Python and Python knows where to find the 
necessary libs. Any online docs describing this? Thanks!

Re: Custom Python Runtime

[Jack]

Thanks for all the replies. It would be great to have all customization
related information on one doc page.

A few more questions:

1. One Windows, it's possible to zip all files in a Python24.zip. I'm not
very clear if it's used in the stardard distribution. What can,
and what can not be put into this file? I suppose zip file will help
reduce the distribution size.

2. I remember trying the compiler option to strip doc strings didn't
help but maybe I didn't do it right. I had to write some code to compile
selected py files. Is there a way to compile a stripped Python with
compile time options?

3. Some files go to the Windows\system32 directory, including some win32all
files. Can they be in the current directory as python.exe?

4. Are the registry entries necessary?

Thanks

Gabriel, thanks for the reply. The error is that the DLL can not be found. I

Is a "real" C-Python possible?

[Jack]

I understand that the standard Python distribution is considered
the C-Python. Howerver, the current C-Python is really a combination
of C and Python implementation. There are about 2000 Python files
included in the Windows version of Python distribution. I'm not sure
how much of the C-Python is implemented in C but I think the more
modules implemented in C, the better performance and lower memory
footprint it will get.

I wonder if it's possible to have a Python that's completely (or at
least for the most part) implemented in C, just like PHP - I think
this is where PHP gets its performance advantage. Or maybe I'm wrong
because the core modules that matter are already in C and those Python
files are really a think wrapper. Anyhow, if would be ideal if Python
has performance similar to Java, with both being interpreted languages.

I guess this is subjective :) - that's what I felt in my experience

I understand. Python modules implemented in Python - this is how
Python gets its really rich library.

I think most Java-Python benchmarks you can find online will indicate

The second articple does have a column for Psyco. It helps in some areas
but still not good enough to stand up against Java. Plus, Psyco is not the
main stream and has stopped development.

I'm also wondering, if Psyco is the right way to do, any reason it's not
being integrated into standard Python?

Strict mode?

[Jack]

While enjoying the dynamic feature of Python I find it difficult to refactor 
code without breaking it. For example, if I modify a function to take more 
arguments, or arguments of different types, I'll need to manually find out 
all places where the function is called and make sure I modify them all, 
unlike in C/Java, where the compiler will do the work of checking function 
signatures, etc. I suppose there isn't a strict mode in Python. It would be 
helpful though, when I don't need things to be so dynamic, and this is often 
the case, when it comes to function arguments and return values, for 
example. Even a module level or function level flag would be very helpful to 
find broken code. Or, are there any third party tools that do this?

IronPython faster than CPython?

I learned a lot from the other thread 'Is a "real" C-Python possible?' about 
Python performance and optimization. I'm almost convinced that Python's 
performance is pretty good for this dynamic language although there are 
areas to improve, until I read some articles that say IronPython is a few 
times faster. I find it amazing that something that's written in C and runs 
on hardware is slower than a .NET app that runs on CLR as managed code:

Can Python installation be as clean as PHP?

[Jack]

I like Python but I don't really like Python's installation.
With PHP, I only need one file (on Linux) and maybe two files
on Windows then I can run my PHP script. This means no installation
is required in most cases. I just copy the file and I get PHP.
Extending PHP is fairly easy, too, just by copying a few DLLs
and modifying the php.ini a bit.

With Python, things are really messy. I have to run the installer
to install dozens of directories and hundreds of files, and I don't
really know if  all of them are necessary. Plus, lots of libraries
are in .py, which is of course not as efficient/clean as having all
of the core functions built-in in the C/C++ core, like in PHP.

Then again, I do like the Python language. It would be great if
Python (or a variation of Python) can be made the PHP way, one
executable file, and you get everything.

Using a proxy with urllib2

[Jack]

I'm trying to use a proxy server with urllib2.
So I have managed to get it to work by setting the environment
variable:
export HTTP_PROXY=127.0.0.1:8081

But I wanted to set it from the code. However, this does not set the proxy:
httpproxy = '127.0.0.1:3129'
proxy_support = urllib2.ProxyHandler({"http":"http://"; + httpproxy})
opener = urllib2.build_opener(proxy_support, urllib2.HTTPHandler)
urllib2.install_opener(opener)
I'm using it from a web.py URL handler file, not sure if it matters.

I have another question though. It seems that using either of the
methods above, the proxy will be global. What if I want to use
a proxy with one site, but not with another site? Or even use a
proxy for some URLs but not others? The proxy having to be global
is really not convenient. Is there any way to do per-fetch proxy?

I find out why it doesn't work in my code but I don't have a solution - 
somewhere
else in the code calls these two lines:

opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
urllib2.install_opener(opener)

and they override the proxy opener. Could anyone tell me how to use both 
openers?

benchmark

[Jack]

I know one benchmark doesn't mean much but it's still disappointing to see 
Python as one of the slowest languages in the test:

swig and DWMAPI.dll

[Jack]

Hello,

When I try and compile a C++ project into a _mystuff.pyd file using
swig with wxDev-C++ it works. I can import, run and everything else in
python.

When I try to compile with g++ command line or code::blocks, compiles
just fine but when I try to import it I get this error:

File "", line 1, in 
  File "D:\python\spinmobules\speedy.py", line 7, in 
import _speedy
ImportError: DLL load failed: A dynamic link library (DLL)
initialization routine failed.

Running "dependency walker" tells me that DWMAPI.dll is missing. This
is a file that apparently is only on windows vista.

Has anyone run into this problem? Is there an easy solution?

Thanks,
Jack

Or, an equally excellent answer would be "you still use swig? That's
so outdated. Try Awesome McAwesomestein's Awesome C++ to Python
Autowrap"

ctypes: return a pointer to a struct

[Jack]

I'm not able to build IP2Location's Python interface so I'm
trying to use ctypes to call its C interface. The functions
return a pointer to the struct below. I haven't been able to
figure out how I should declare the return type of the functions
and read the fields. Any hint is appreciated.

typedef struct
{
 char *country_short;
 char *country_long;
 char *region;
 char *city;
 char *isp;
 float latitude;
 float longitude;
 char *domain;
 char *zipcode;
 char *timezone;
 char *netspeed;
} IP2LocationRecord;

Re: ctypes: return a pointer to a struct

[Jack]

Thanks for the prompt and detailed reply. I tried that but was getting this 
error:

AttributeError: 'LP_IP2LocationRecord' object has no attribute 
'country_short'

Here's my version, which I think is equivalent to yours:
(as a matter of fact, I also tried yours and got the same error.)

class IP2LocationRecord(Structure):
_fields_ = [("country_short", c_char_p),
("country_long", c_char_p),
("region", c_char_p),
("city", c_char_p),
("isp", c_char_p),
("latitude", c_float),
("longitude", c_float),
("domain", c_char_p),
("zipcode", c_char_p),
("timezone", c_char_p),
("netspeed", c_char_p)]

IP2Location_get_all.restype = POINTER(IP2LocationRecord)
IP2LocationObj = IP2Location_open(thisdir + '/IP-COUNTRY-SAMPLE.BIN')
rec = IP2Location_get_all(IP2LocationObj, '64.233.167.99')
print rec.country_short
IP2Location_close(IP2LocationObj)

That worked. Thank you!

best way to index numerical data ?

[Jack]

Hi I have a lot of data that is in a TEXT file which are numbers does
anyone have a good suggestion for indexing TEXT numbers (zip codes,
other codes, dollar amounts, quantities, etc). since Lucene and other
indexers are really optimized for Alpha character indexing. What
approaches are typically taken in computer science for example to index
text numbers..hash maps or something else ??

Thanks,

Jack
