Re: Connecting Google News
Chris,
(Also, please upgrade your Windows box to run Python 2.7.)
It's not /my/ Windows box. I'm allowed to run my script, that's
all. My Windows box is actually that with 3.6.
http = httplib.HTTPSConnection('news.google.com')
http.request("GET","/news?ned=es_MX" ,
('Location', 'https://news.google.com/news/?ned=es_mx=es'),
...
See that Location header? The web server wants to redirect you
somewhere. Your low-level HTTP library does not handle redirects
automatically, so you’d need to take care of that yourself.
I didn't notice the bar just before ?ned ! I don't know how many
times I've compared the URLs without realizing it was added. Silly
me!
Thank you

Connecting Google News
Google News used to fail with the high level functions provided by httplib
and the like. However, I found this piece of code somewhere:
def gopen():
http = httplib.HTTPSConnection('news.google.com')
http.request("GET","/news?ned=es_MX" ,
headers =
{"User-Agent":"Mozilla/5.0 (X11; U; Linux i686; es-MX)
AppleWebKit/532.8 (KHTML, like Gecko) Chrome/4.0.277.0 Safari/532.8",
"Host":'news.google.com',
"Accept": "*/*"})
return http.getresponse()
A few days ago, Google News has been revamped and it doesn't work any more
(2.6/Win7, 2.7/OSX and, with minimal changes, 3.6/Win7), because the page
contents is empty. The code itself doesn't raise any errors. Which is the
proper way to do it now? I must stick to the standard libraries.
The returned headers are:

Re: PEP 3131: Supporting Non-ASCII Identifiers
Eric Brunel [EMAIL PROTECTED] escribió en el mensaje Funny you talk about Japanese, a language I'm a bit familiar with and for which I actually know some input methods. The thing is, these only work if you know the transcription to the latin alphabet of the word you want to type, which closely match its pronunciation. So if you don't know that ?? ? is pronounced uriba for example, you have absolutely no way of entering the word. Actually, you can draw the character (in XP, at least) entirely or in part and the system shows a list of them with similar shapes. IIRC, there is a similar tool on Macs. Of course, I'm not saying this allows to enter kanji in a easy and fast way, but certainly it's not impossible at all, even if you don't know the pronunciation.

Re: PEP 3131: Supporting Non-ASCII Identifiers
René Fleschenberg [EMAIL PROTECTED] escribió en el mensaje news:[EMAIL PROTECTED] This is a very weak argument, IMHO. How do you want to use Python without learning at least enough English to grasp a somewhat decent understanding of the standard library? By heart. I know a few _very good_ programmers who are unable to understand an English text. Knowing English helps, of course, but is not required at all. Of course, they don't know how to name identifiers in English, but it happens they _cannot_ give them proper Spanish names, either (I'm from Spain). +1 for the PEP, definitely. But having, for example, things like open() from the stdlib in your code and then öffnen() as a name for functions/methods written by yourself is just plain silly. It makes the code inconsistent and ugly without significantly improving the readability for someone who speaks German but not English. Agreed. I always use English names (more or less :-)), but this is not the PEP is about. Javier -- http://www.texytipografia.com -- http://mail.python.org/mailman/listinfo/python-list
Re: Python Feature Request: Allow changing base of member indices to 1
Paddy, Dijkstra's argument is obsolete, as it is based on how array length was computed many years ago -- if we have an array a = b..e, then the lenght of a is e-b (half open range). Good at low level programming. But a quarter of a century after we know concepts are much better than low level programming and explicit computations -- if we have an array a = b..e, then the length of a should be a.length() (or a.length(b,e)), and it is independent of Hi Javier, You seem to have missed out array *indexing* in your argument, or is array indexing obsolete? Of course, it isn't, but it has evolved over the past 25 years. When Djikstra wrote that, many people (including me) was using a Spectrum--- Now we have OO programming to deal with concepts and a more generic programming. So, to me it's clear his _argument_ is very outdated and cannot be applied directly and withot reservations to modern languages like Python.

Re: Python Feature Request: Allow changing base of member indices to 1
Here is a document giving good reasons for indexing to start at
zero, as in Python.
http://www.cs.utexas.edu/users/EWD/transcriptions/EWD08xx/EWD831.html
The author has done a bit:
http://en.wikipedia.org/wiki/Dijkstra
Dijkstra's argument is obsolete, as it is based on
how array length was computed many years ago -- if
we have an array a = b..e, then the lenght of a
is e-b (half open range). Good at low level
programming.
But a quarter of a century after we know concepts
are much better than low level programming and
explicit computations -- if we have an array
a = b..e, then the length of a should be a.length()
(or a.length(b,e)), and it is independent of
arbitrary ranges, index bases, or even steps
(eg, {-4, -2, 0, 2, 4}).
Of course, the index base should be always the
same _by default_ (individual lists could require
another index base, and that's fine). Otherwise
it would a mess, as you said.

So, what's the point of this thread now? None. In fact, I sent my last post a couple of days ago, so I don't see the point of your message.

I said: Further, I don't understand why l[a:b] has a behaviour which does't depend on its own logic but on that of certain constructs containing slices but which aren't the slices themselves. You give a counterexample: st = This i a string with typo, for example pos = st.find(i ) + 1 # + 1 to get the space after i new_st = st[:pos] + s + st[pos:] but that shows clearly what I was saying -- this tricky syntax means that you have not to write st[:pos-1] in this particular code (but you still have to write it in your mind since it forms part of the logic of the problem). These kind of hacks look perlish to me. Of course, the danger of being off-by-one would be still present, but I would like to note that if you change the syntax to avoid it in some expressions you will find problems in another expressions where otherwise it wouldn't be present (counting from the end with negatives values is particularly funny). The same applies if the first element is 1 instead of 0, for example. Then, why not to leave that to the logic of the problem and not to tricky syntaxes?

If you have to add or substract 1 in an expression containing slices (or contained in a slice), this belongs to the logic of the expression, not to the slices syntax.

I particularly hate it, but Python has lots of good things which compesate that (another annoying point of Python are slices -- mine are always off by 1).
