I'm not familiar with red hat. But looks like this is now a sysadmin
problem. I could install pycurl under freebsd and ubuntu too.
I have some code that might be able to PUT through a proxy for you. Please
look at the attached file.
You can setup a proxy this way:
import MozzillaEmulator
MozzillaEmulator.DEFAULT_**PROXIES = {
'http':'http://user:password@**proxy.host.com:3128http://user:passw...@proxy.host.com:3128
',
'https':'http://user:password@**proxy.host.com:3128http://user:passw...@proxy.host.com:3128
',
}
And here is how you use it:
dl = MozillaEmulator.**MozillaEmulator()
put_url = http://some_url_to_put_to;
headers = {'Content-Type':'application/**xml;charset=UTF-8'}
data = open(some_file,rb).read()
response = dl.download(put_url,data,**headers,put_method=True)
If you don't set the put_method flag, then it will POST instead. (But in
that case, post data must be a valid post data field fields and values.) If
you don't give post_data then it will GET. The PUT method was tested without
a proxy, and the GET and POST methods were tested with and without proxy.
Actually I have tried to do PUT through a proxy, but it didn't work. But it
was a restriction on the proxy side. (As far as I can recall, the error
message came from the proxy server, something about unsupported request?).
So it *might* work for you, with the right proxy server that supports PUT
requests.
Also be aware that this version uses urllib2. Although it can use https
protocol, it doesn't check the server's certificate.
Mozilla Emulator works like a charm.
Also managed to install pycurl and the same works too.
Thanks. :)

PUT with proxy-support

What did you try? What problems did you run into?
I'm sure there is a way in Python, and chances are you were already
close to finding it -- show us what you tried, what actually happened,

Hi Thomas,
so one of my tries was:

import httplib
import httplib2
url = 'http://alatheia.zenfs.com/testing/shashwat'
body_content = 'CONTENT GOES HERE'
proxy = 'ca-proxy.corp.xyz.com:3128'
params = {
'x-sws-version' : '1.0',
'x-sws-access' : 'public',
'User-Agent' : 'CacheSystem',
'Cache-Control' : 'public',
'Content-Type' : 'text/plain',
'App-Auth' :
'v=1;a=client.alatheia.prod;h=10.16.19.23;t=1316594650;s=AeEYJMMfElN74fnWD3GlXJ4J.1KiQFg--',
}
httplib2.debuglevel=4
h = httplib2.Http(proxy_info = httplib2.ProxyInfo(3, '
ca-proxy.corp.xyz.com:3128', 3128))
resp, content = h.request(url, PUT, body=body_content, headers = params)
print resp
print content
Output:
connect: (alatheia.zenfs.com, 80)
Traceback (most recent call last):

The reason I can trace it is because,
I can use PUT on http://alatheia.zenfs.com/testing/shashwat but not on
http://alatheia.zenfs.com/ however host is resolved.
Again port 80 is used even when I use specific port (3128, in this case).

Generally such libraries work by bi/trigram frequency analysis, which means you're going to have a fairly high error rate with such small phrases. If you're only dealing with a handful of languages it may make more sense to combine an existing library with a simple dictionary lookup model to improve accuracy. Katie Infact I'm dealing with very few languages - German, French, Italian, Portugese and Russian. I read papers mentioning bi/tri gram frequency but was unable to find any library. 'guess-language' doesn't perform at all. The cld (Compact Language Detection) module of Google chrome performs well but it is not a standalone library ( I hope someone ports it ).

I was trying some sort of timed programming challenges which require getting the value from url and auto-posting. Here is what I was doing - http://securityoverride.com/challenges/programming/10/index.php Here is the content : In order to complete Programming Challenge 10, you must code a script that will search the moo directory, and all subdirectories for the three passwords below. Once complete, you must submit the folder number that goes with each password (the folder that the password was found in). Example: 1:e92nb0s4; 50:un2r9nw7; 100:48bn20b6 Then three _random_ passwords are generated. So far so good. I did wrote a code using mechanize to do this.

The method to recognise them eluded me. Eyes are not good enough :) I have now joined Python-List and will follow the correct route. I have used a method suggested that has made the problem redundant, though it will bug me from now on. g = [] def divsum(n): return sum(i for i in range(1, n) if not n % i) You can optimize divsum. Remember that factors exist in pairs except when numbers are squares. Like say 12 have factors = 1, 12, 2, 6, 3, 4 so you can run the loop till sqrt(n) for n since floor(sqrt(n)) = 3 where n = 12 now factors are , (1, n/1), (2, n/2), (3, n/2). for a square number say n = 9, the factors are (1, 3, 12) If you run the loop till sqrt(n) for n since floor(sqrt(n)) = 3 where n = 9 we get the factors as (1, 9), (3, 3) One of the factor will be redundant, so you need to take care of that. for x in range(1, 2, -1): c = divsum(x) v = divsum(c) Can be done as, c, v = divsum(x), divsum(divsum(x)) if v == x and v != c: g.append(divsum(x)) No need for else part, what is the use ? else: continue print(sum(g)) You could pack this up as, sum(i for i in range(1, 0, -2) if divsum(divsum(i)) == i and divsum(i) != i) 31626 -- Rog http://www.rog.pynguins.com -- http://mail.python.org/mailman/listinfo/python-list -- ~l0nwlf -- http://mail.python.org/mailman/listinfo/python-list

Re: Numpy: Multiplying arrays of matrices

I want to perform matrix multiplication between corresponding matrices in these arrays. I had thought that dot() might do this, but it appears not, because e.g. applying it to two 3-d arrays gives a 4-d array, not another 3-d array. I'd also like to be able to find the inverse of each matrix in one of these arrays, but again, inv() doesn't do what I want -- it only works on 2-d arrays. Any thoughts on how to achieve these things using numpy functions?

Just go through each letter of word checking for its existence in
dict2. Return False if one misses, and True if you get through the
whole word:
def ...():
for c in word:
if c not in dict2:
return False #if any character is not in dict
return True # otherwise
If you know of generator expressions, and remember that True and False
are 1 and 0 respectively, then this works

ok but how do we address the fact that letter e needs to have the
value 2 in the dictionary if it was to be True? in my example this
condition is not met so the check would return False. Word is not
entirely composed of letters in dict2, one of the letter is not in
dict2 i.e. the 2nd e
Seems You did not understood Gary's solution. It is correct. Also, you asked
for
'i want to know if word is entirely composed of letters in dict2' which you
are getting.
Did you tried running the code ?
So finding a matching key seems to be the easy part, checking if the
number of ocurrences of letter in 'word' == letter.value seems to be
the tricky part

Re: Performance ordered dictionary vs normal dictionary
It depends on the problem. A dictionary is a hash table. An ordered dictionary is a binary search tree (BST). Those are different data structures. The main things to note is that: - Access is best-case O(1) for the hash table and O(log n) for the BST. - Worst case behavior is for access is O(n) for both. The pathologic conditions are excessive collisions (hash) or an unbalanced tree (BST). In pathologic cases they both converge towards a linked list. - Searches are only meaningful for == and != for a hash table, but BST searches are also meaningful for , , =, and =. For this reason, databases are often implemented as BSTs. - A BST can be more friendly to cache than a hash table, particularly when they are large. (Remember that O(1) can be slower than O(log n). Big-O only says how run-time scales with n.) Thanks, this was really insightful :) -- http://mail.python.org/mailman/listinfo/python-list

You could write:

On OSX you can use 'DictionaryServices' API eg., import sys import DictionaryServices word = .join(sys.argv[1:]) print DictionaryServices.DCSCopyTextDefinition(None, word, (0, len(word))) Gives the meaning of the input word (works with python 2.5) You can use this script for Vi (~/.vimrc) if you want, control+a will do a spell check. Toggle Spell-Check set spell spelllang= function ToggleSpellCheck() if spelllang == en set spelllang= else set spelllang=en endif endfunction command! ToggleSpellChecking call ToggleSpellCheck() nmap c-a :ToggleSpellCheckingcr But again am not aware of your use case.

We need more issue reviewers. Clearly. If you want to contibute, opportunity is here. With 500 orphans, and 2200 other open issues, there must be something that matches your interests and abilities. Use other search fields to narrow the choices. If you want to contibute to the tracker, this may help: http://wiki.python.org/moin/TrackerDocs/ Then read examples of comments already there. Or consider my first-response comment to http://bugs.python.org/issue8990 To write that, I * verified the reported behavior, though I forgot to explicitly say so; when doing so, include version and system (such as 3.1.2, WinXP), as that is sometimes helpful. * read the relevant doc section and pasted it in to establish a basis for discussion (the OP might have done that, but did not, so I did). Everyone reading this should at least be able to do this much for an issue like this, and this much *is* helpful. * compared behavior and doc and concluded that there is a bug. * read the posted patch as best I could, which is not much in this case, but it at least looked like a real diff file. * noticed that the diff did *not* patch the appropriate unit test file. * discussed two possible fixes and identified which the OP choose. * wrote an 'executive summary' both for the OP and future reviewers. Oh yes, I also adjusted the headers. Although new reviewers cannot do that, you *can* suggest in the message what changes to make. Special offer to readers of this thread, especially new reviewers: if you make such a suggestion, you may email me, subject: Tracker, with one clickable link like the above, cut and pasted from the browser URL box, per line of the message. Perhaps you are shy and uncomfortable saying much. Well so was I. I started about 5 years ago with *safe* comments and have s l o w l y expanded my comfort zone. The shock of discovering this week that there are 500 orphans, some 2 years old, expanded it. After no response for a year or two, even an imperfect response must be better than nothing. While there is occasional negativity on the tracker, I believe it averages less per message than python-list, which itself is pretty decent.

[issue9033] cmd module tab misbehavior
Shashwat Anand anand.shash...@gmail.com added the comment:
It seems readline module is not installed on your system.
Quoting Ned Deily's comment from issue8365 which will most probably solve your
issue:
Issue6877 (and subsequent fixes in Issue8066) allows the Python readline
module to be built and linked with the OS X editline (libedit) library rather
than with the GNU readline library (which is not included with OS X). However,
the libedit included in versions of OS X prior to 10.5 is considered too broken
to use here.
By default, if you do not specify an --with-universal-archs other than 32-bit
to configure or if you do not explicitly set MACOSX_DEPLOYMENT_TARGET to
another value, configure defaults to using 10.4 (or earlier) so the building
of the readline module is skipped. You can check this:
from distutils.sysconfig import get_config_var
get_config_var('MACOSX_DEPLOYMENT_TARGET')
'10.4'
(Whether this is the best default is another question.)
As it stands, to be able to build the readline module, either:
(1) supply the GNU readline library as a local library, or
(2) ensure you are building with a deployment target of at least 10.5. For
example:
./configure MACOSX_DEPLOYMENT_TARGET=10.6 ; make
Also note that option (2) is not available for 3.1.x since the changes to
support editline/libedit were not ported to it; they are, however, in 2.6.5,
2.7 (trunk), and 3.2 (py3k)

[issue8898] The email package should defer to the codecs module for all aliases
Shashwat Anand anand.shash...@gmail.com added the comment:
from email.charset.ALIASES most of them failed to be recognize by codecs module.
for i in email.charset.ALIASES.keys():
... try:
... codecs.lookup(i)
... except LookupError:

email.charset.ALIASES[i]))

Not recognized by codecs : alias latin-8 mapped to iso-8859-14
Not recognized by codecs : alias latin-9 mapped to iso-8859-15
Not recognized by codecs : alias latin-2 mapped to iso-8859-2
Not recognized by codecs : alias latin-3 mapped to iso-8859-3
codecs.CodecInfo object for encoding iso8859-1 at 0x10160af58

[issue8898] The email package should defer to the codecs module for all aliases
Shashwat Anand anand.shash...@gmail.com added the comment:
We need to add aliases for those codecs. The current aliases
list only supports the format latinN for N in 1-10.
latinN means latin1 to latin10 ?
But latin_1 is a recognized alias.
codecs.lookup('latin_1')

I have not much idea but Online Judges like SPOJ/codechef have regular programming-contests and python is one of allowed languages. So yes, it's possible.

My understanding is that \b matches a space at the start or end of a

What am I missing here? I suspect I am doing something very stupid.

Also what you are probably looking for is this I guess,

m = p.match('word word')
assert m

conn = sqlite3.connect('dbdump.sqlite')
c = conn.cursor()
conn.in_transaction
False
c.execute('CREATE TABLE foo (id integer, name text)')
sqlite3.Cursor object at 0x1004a7730
conn.in_transaction
False
It gives True for Insert and False for Select. perfect Ok. However It should
give True when we Create tables ?
Adding unit-test which upon showing this behavior fails the test.

Re: launching vi/vim from console

prefer it that way generally

Since I could not find anything I wrote this:

Please suggest if there is any better alternative for this.
I tried googling for this but could not find anything interesting.

import os
os.system.('vi')
or you can start an ipython shell
and start vi using
!vi
Thanks. I wanted something like ipython.
I will give it a try.
