Re: CGI templating with python
Django will probably get you where you want to go the fastest: http://www.djangoproject.com/ In particular, its admin interface will probably automatically generate a usable UI for you without your having to write many templates at all. Robert, Thank you very very much. I had a brief peruse of django last night and it does indeed look like what I am after! Will take me some time :) to delve into it deeper but I wanted to thank you! -- http://mail.python.org/mailman/listinfo/python-list

CGI templating with python
Hi there, Years ago I wrote a LAMP app using python. I find I need a simple web data entry tool to store records (stock research) and when I enter a stock ticker, to pull up all the past research I have done. I am imagining fields like ticker, date, pulldown menus for various options, long text for comments etc.. It's a very light weight application, so I was wondering if using something like Cheetah is the best way to do this? Or should I research Zope further or are there any other suggestions? Environment: - Python 2.5 (w/ MySQLdb) - MySQL 5.1 - Windows Vista Many thanks in advance! -- http://mail.python.org/mailman/listinfo/python-list

Utility to screenscrape sites using javascript ?
Hi there, I have a service I subscribe to that uses javascript to stream news. Ideally I would like to use python to parse the information for me. Note there is an option to take a static snapshot of the current stream but that is still done via Javascript. (I can reference the snapshot with a unique URL though, so I can pass that to a parser as long as it can resolve the javascript and get at the content) I had a quick look at Windmill but it doesn't appear to be what I am looking for. Does anyone else have any experience in screenscraping sites that utilise javascript? Can you share how you did it and perhaps some sample code if possible?

Using jython to call python procedures/methods
Hi there, I have an application that only publishes a Java API. I can use jython to access java classes, but jython currently (to the best of my knowledge) does not support numpy/scipy. Ideally I would like to have jython call a native python routine where I have the numpy/scipy procedures already written. Does anyone have any experience with this? Is it possible? I had toyed with the idea of having jython/java write the data to a file/database and then manually kick off the python process, but ideally I would like this as automated as possible.

jython and java application
Hi there, Apologies if this is on the wrong group, this is a jython question. Please redirect me to the correct group if this is in error. I have a java application that takes no arguements. When I run it, it spits out output, and finishes. I am trying to run this java application from jython 2.5.1, JRE6. I have made simple Hello World java classes be callable from a simple jython script, yet I am stumbling on the java main construct in the application. print krbtest.SimpleHistoricTutorial().main() obviously gives me an args error (expected 1, got 0) as the definition in the java application is: public static void main(String[] args) The jython code is as follows: import krbtest # was messing with this to pass a java formatted string but to no avail from java.lang import String print krbtest.SimpleHistoricTutorial().main() # Any advice greatly appreciated! Especially with how to call main() with arguments from jython. Apologies in advance again if this is the wrong group. -- http://mail.python.org/mailman/listinfo/python-list
Re: jython and java application

Modified jython script to:
# Eclipse package name for java application
import krbtest
import java.lang as lang
from java.lang import String
from jarray import array
myargs=array([],String)
krbtest.SimpleHistoricTutorial().main(myargs)
Now I get:

I would post the java app but its quite large, but the main defn:
public static void main(String[] args) throws Exception
{
SimpleHistoricTutorial example = new SimpleHistoricTutorial();
example.run();
}
Is pretty vanilla. I have tried making the run() a public method and
call it, all to no avail.
Note, the Java app works fine standalone, I just need to call it from
jython.
Again, any help appreciated.

Problem with reading CSV file from URL, last record truncated.
Hi,
I am trying to download from a URL, a CSV using the following:
import re
import urllib, urllib2, cookielib
import mechanize
import csv
import numpy
import os
def return_ranking():
cj = mechanize.MSIECookieJar(delayload=True)
cj.load_from_registry() # finds cookie index file from registry
# set things up for cookies
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
urllib2.install_opener(opener)
reply = opener.open('http://ichart.finance.yahoo.com/table.csv?
s=CSCOa=00b=01c=2009d=01e=2f=2010g=dignore=.csv').read()
fout=open('csco.csv','wb')
fout.write(reply)
fout.close
fin=open('csco.csv','rb')
table = csv.reader(fin)
fin.close
for row in table:
print row
return_ranking()
I need to use cookies etc (mechanize/urllib2) for a different, more
complex URL but since it wasn't working, I went back to a simple Yahoo
example (above) which I have working with urllib (not urllib2).
The behaviour I am seeing is that the last record is being truncated:
(sample output)
['2009-04-08', '17.29', '17.33', '16.94', '17.13', '45389100',
'17.13']
['2009-04-07', '17.20', '17.25', '16.58', '16.85', '59902600',
'16.85']
['200']
A friend said I should do the above writing out to a file and have
csvreader read in the file, but as you can see, to no avail!
Any help greatly appreciated! Note that urllib.urlretrieve works
perfectly but I give up the ability to import cookies from my registry
which is all important (AFAIK anyway mechanize requires urllib2).
Any help greatly appreciated.

Use existing IE cookie
Hi there,
Relevant versions: Python 2.5, Vista Home, IE7
I am trying to scrape a website I have browsed manually in the past,
and also manually selected my options, and now want python to use my
existing cookie from the manual browse when downloading data.
Using: http://code.activestate.com/recipes/80443/ I have found the
name of the relevant cookie, just after reading urllib2 docs, I
can't see how to send or have my python instance use MY existing
cookie.
Using the following:
***
import re
import urllib2, cookielib
# set things up for cookies
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor())
urllib2.install_opener(opener)
reply = urllib2.urlopen('foo.html').read()
print reply
***
This does return data, just default data, not the data from the
options I set up when manually browsing.
My sense is that I need something in the () part of
HTTPCookieProcessor() but I have no idea as to what... the docs say
cookiejar but the only code examples I have found are to create a
cookiejar for the existing Python session, not to use the cookies from
my prior manual meanderings.
Any help greatly appreciated.

Re: Use existing IE cookie
Using:http://code.activestate.com/recipes/80443/ Thanks for the prompt reply, Diez!

Any clues? TIA! -- http://mail.python.org/mailman/listinfo/python-list
Re: Use existing IE cookie
What does you full example look like, including the
cookie-acquisition-stuff?
Diez
I ran them seperately, hoping for a clue as to what my cookiejar
was.
The cookie-acquisition stuff returns screener.ashx?v=151 when I
search with my domain I am interested in. I have tried
urllib2.HTTPCookieProcessor('screener.ashx?v=151') but that failed
with attr has no cookie header.
From the HTTPCookieProcessor doco, it appears that non-IE browsers
have a cookie file (and example code) but from what I can tell IE uses
a hidden folder. (you can set your location in IE but it appends a
folder \Temporary Internet Files -
From: http://docs.python.org/dev/library/cookielib.html
***
This example illustrates how to open a URL using your Netscape,
Mozilla, or Lynx cookies (assumes Unix/Netscape convention for
location of the cookies file):
import os, cookielib, urllib2
cj = cookielib.MozillaCookieJar()
cj.load(os.path.join(os.environ[HOME], .netscape/cookies.txt))
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
r = opener.open(http://example.com/;)
***
Not sure how to adapt this for IE.

You could create a file that resembles the cookies.txt - no idea how that

Yeah unfortunately I just tried Firefox and it uses cookies.sqlite

Re: How to quit a Windows GUI program gracefully with Python under Cygwin?
Thanks.
After I confirmed 'Alt-F4' would terminate and close a win32
application running independently,
I installed 'SendKeys' module and tested with the following code under
both Cygwin and Python Windows
import os, SendKeys
os.system('program datafile')
SendKeys.SendKeys(
{PAUSE 0.25}
%{F4}
)
What happened was that the 'program' ran correctly, but it stayed, not
closing the window
under Cygwin and Python Windows. So it seems to me that this does not
work.
One more thing: How do I control the pause time if I do not know the
execution
time of an application?
