Ask yourself, why aren't programs written in assembly if it's so good? (1) It's platform dependent. Do you really need a separate program for every single hardware platform you want to run Quicksort on? (2) Writing assembler is hard, really hard. And even harder to debug. (3) Modern C compilers can produce better (faster, more efficient) machine code than the best assembly code written by hand. Honestly, this question has been resolved twenty years ago -- thirty years ago, maybe there was still a good point in writing general purpose code in assembly, but now? It's just showing off. Unless you're writing hardware specific code (e.g. device drivers) it is pointless, in my opinion. I think that mixing assembly and python is a gimmick of very little practical significance.

Ah, so by "bypasses" you mean "under certain specific circumstances
bypasses". By all means file a bug report on this, I agree that
bypassing the optimization for file subclasses (assuming your

Re: If Not CGI...
I've caught a lot of flack (imagine that) about using CGI. The main reason is that CGI has the overhead of loading & unloading the Python interpreter on every request. The other methods load the Python interpreter once (or a small, fixed-number of times), then handle lots of requests from that process (or pool of processes), and then optionally unload if server-load drops. However CGI is old and fairly entrenched, so it's easy to find with cheap hosting services -- what do they care if your site is slow? I understand there are several other options, to wit: mod_python, fastcgi and wcgi. I've messed around with mod_python without luck. What are your suggestions? Generally, one writes to a framework (Django[1], web.py[2], TurboGears[3], CherryPy[4], etc) that either has a preferred/suggested method of interface, or allows you to plug into [m]any of the items you list. I know Django is happy with mod_python and wsgi (and I suspect fastcgi, but I'll let you google that). YMMV with the others. I've even seen an abomination of a hack that ran Django under CGI (whie, is the performance bad!). I think the general direction of the Python web-world seems to be moving toward WSGI (and Graham Dumpleton's work on mod_wsgi[5]; IIUC, he was heavily involved in the initial mod_python) instead of mod_python. Since you seem fairly adamant about *not* using a framework and cobbling together the universe from the ground up, you might look into Paul Boddie's "WebStack"[6] which abstracts away a number of the main interfaces into a common interface. Kindly, his work even allows you to plug into a CGI interface since that's what you're familiar with, and then shift to a different interface. -tkc [1] http://djangoproject.com [2] http://turbogears.org [3] http://webpy.org [4] http://www.cherrypy.org [5] http://code.google.com/p/modwsgi/ [6] http://www.boddie.org.uk/python/WebStack.html -- http://mail.python.org/mailman/listinfo/python-list

I've > messed around with mod_python without luck. What are your suggestions? Its a slightly complicated question. First of all, it is not absolutely *wrong* to use CGI. Its just simply decades out of date, slow, and has certain problems. Primarily, that one must start Python for each and every request. That adds up: that adds up a LOT over time. The "solution" to all of these are various methods to run Python once, and keep it running and loaded, and simply call into it (i.e., execute some function you've defined) for those requests that need to be dynamic. mod_python accomplishes this by embedding Python into Apache directly. After you set it all up, there's various ways you can access it. The simplest is the publisher handler. With it, you can 'call' a Python function by linking to, say, /myform.py/view -- it'll call the 'view' function in 'myform.py'. With it, check out http://www.modpython.org/live/current/doc-html/tutorial.html "without luck" is a worthless statement to make, so I can't comment on it. But with mod_python, you wouldn't just be running it and then running your existing code as-is. The interface between the web server and your code is different in it, so you'll have to reorganize some stuff. FastCGI is a different kind of approach to the problem; it launches Python alongside Apache, and that Python stays alive forever. It just redirects requests to said process when they come in. I know very little about this model, but believe its meant to sort of mimic a CGI environment so you can sort of migrate to it easier, but I'm not entirely sure. So I can't comment on this directly, but http://docs.python.org/howto/webservers.html seems interesting (Though it speaks of ALL of these options, so is a good read anyways) Then there's mod_wsgi; this is like mod_python, but approaches the problem differently, with a bit more formal structure with an eye for interoperability. It implements the Web Server Gateway Interface specification, and lets you easily load up "wsgi apps" and "wsgi frameworks" which are a very, very nifty way to write modern web applications. But the thing is: a WSGI web application looks and is shaped nothing like a CGI application. They're awesome. Btu different. Writing a WSGI app from scratch without a framework is possible, but it seems like a terribly painful thing to go about doing. Instead, most people who are writing modern Python web applications, use some sort of framework. Django is one of the most popular. I like it. But I prefer pylons-- its a little more low level, and that suits me. There's also TurboGears, webpy, and on and on and on. The cool thing about WSGI applications is that they are "stacks"; there's a lot of "middleware" that can sit between the server and your end-application. You can add features and functionality and capabilities to your app just by adding another piece of middleware. For example, do you want to store state about what a user is doing? The things in their shopping cart, for example? A really, really elegant way is to use a "session" middleware -- Beaker for instance. It creates a unique session key, and sets it on the user's cookies. In your web application now, you can associate any kind of data you'd like with that key. And you can even remember stuff about that user if they return to your app later. Now, you could do that all by hand-- but its painful, and doing it right is not trivial. My suggestion? I can't really give you one. You're in the middle of a project. Doing it "right" from this point is basically a rewrite -- though it may not take as long as you suspect, if you use something like Django which is -very- easy. So maybe my suggestion is for now, to figure out what's wrong with mod_python for you. It works just fine. But then when this project is over, sit down and load up Django (or another of the options: look around, find one that tickles you), and spend a few days re-doing this project in that. Not for real, but for practice, to figure out how you'd do it in a proper framework. See how you like it. See how it works. -- Stephen Hansen ... Also: Ixokai ... Mail: me+list/python (AT) ixokai (DOT) io ... Blog: http://meh.ixokai.io/ P.S. An added plus to the WSGI app's: they'll encourage (nay, force) you to write better code.

It worked for me when connecting to one particular site. I couldnt tell you why though... I guess its worth a shot. from suds.transport.https import HttpAuthenticated import urllib2 t = HttpAuthenticated(username='me', password='password') t.handler = urllib2.HTTPBasicAuthHandler(t.pm) t.urlopener = urllib2.build_opener(t.handler) c = client.Client(url='http://xxx.xxx.xxx.xxx/path/to?

Most likely you need a cookie. You'll probably have to set up a cookie
store for use with urllib2, then request the page that the search form
is on so that the cookie is generated, and then make your post with your
search terms.

Oh, yes, thanks for pointing that out, that was a dirty hack for
solving some error I was getting with pydoc. I'll remove that, thanks
for pointing that out.

What I don't get is: what do you mean I'm importing my main script elsewhere by runing "python village.py"? SomethingBuiltError is defined in the same script that I'm runing, I didn't import it, did I? If you could please clear it up for me... or point me to relevant literature, that's also cool, I couldn't find this thing explained anywhere.

Try mechanize : http://wwwsearch.sourceforge.net/mechanize/
import mechanize
response = mechanize.urlopen("http://www.bundes-telefonbuch.de/";)
forms = mechanize.ParseResponse(response, backwards_compat=False)
form = forms[0]
form["F0"] = "query" #enter query
html = mechanize.urlopen(form.click()).read()
f = open("tmp.html","w")
f.writelines(html)
f.close()
Or you can try to parse response but I think that their HTML is not
valid

scraping from bundes-telefonbuch.de with python
hello, i'm new on this group, and quiet new to python!
i'm trying to scrap some adress data from bundes-telefonbuch.de but i
run into a problem:
the link is like this:
http://www.bundes-telefonbuch.de/cgi-btbneu/chtml/chtml?WA=20
and it is basically the same for every search query.
thus i need to submit post data to the webserver, i try to do this
like this:
opener = urllib2.build_opener()
opener.addheaders = [('User-Agent', 'Mozilla/5.0 (compatible;
Konqueror/3.5; Linux) KHTML/3.5.4 (like Gecko)')]
urllib2.install_opener(opener)
data = urllib.urlencode({'F0': 'mySearchKeyword','B': 'T','F8': 'A ||
G','W': '1','Z': '0','HA': '10','SAS_static_0_treffer_treffer': 'Suche
starten','S': '1','translationtemplate': 'checkstrasse'})
url = 'http://www.bundes-telefonbuch.de/cgi-btbneu/chtml/chtml?WA=20'
response = urllib2.urlopen(url, data)
this returns a page saying i have to reenter my search terms..
what's going wrong here?
Thanks!!

Re: how to get bit info
Back9 writes: > Hi, > > I have one byte data and want to know each bit info, > I mean how I can know each bit is set or not? Other than the tedious anding, oring and shifting, you can convert your byte to a string (with function bin) and use normal string handling functions to check if individual bits are 0 or 1. String format is also handy if you happen to need to do things like reversing the bit order or slicing and joining together various bits from different bytes. I seem to invariably need to do some bit order reversing when I mess around with serial data, which is one reason why I like Python. -- http://mail.python.org/mailman/listinfo/python-list
