Can you be more specific? Creating a web server in Python can be done in one line: python -c "import CGIHTTPServer; CGIHTTPServer.test()" will start a web server that serves static files and cgi's. There are *many* options for creating a full web application in Python (too many options, some say). Two currently popular choices are Django and TurboGears but they may be overkill for what you need. Anyway we really need more details of what you want to do and why to be able to help you.

Thanks. I found the windows help and support center. It's not obvious how to use it. Could not find an index search box. I finally did find the windows web newsgroup, and found where someone posted a question about environmental variables, in which he just happened to list the same information you did about environment variable. Environmental variable is not in the windows help glossary. Before today I did not know that a windows help existed.

Thanks, I've gotten some further again, but the following problem is
that I am using this connection to get some cookies, which are read
from the page headers. As far as I can see, urllib2 puts the page
headers into a dictionary, which is not what I need, because there are
4 different set-cookie headers sent out by the site, and I get only
one "set-cookie" value. Am I right in this, and is there a way around
it?

Re: [Tutor] odbchelper
Hi! How have you started the script? As far as I could see, in the Chapter 1 of "Dive into Python", the odbchelper.py is just a script-File and not a module to be imported, therefore the Exception with the "ImportError". I do not have a Windows box here to check if the problem is with the PythonIDE. Testing with idle ( the python ide ) under solaris and putting the source-Code from Chapter 1 into the buffer, saving it and just starting with "F5" = "Run Module" just gives the string. Otherwise under unix just start "python odbchelper.py" on the commandline.

You need this file stored somewhere on the python search path; the current working directory is probably a good choice.

Have you tried using a CookieManager as shown in the first example here:
http://docs.python.org/lib/cookielib-examples.html
Once you set up your opener with a CookieJar the cookies should be
handled automatically - if a server sets a cookie it will be remembered
and returned back to the server on subsequent requests.
This page has more examples though again IMO they are overly complex:

It is both, if by "just a script-File" you mean a top-level program intended to be run from the command line. If you import odbchelper it will give you access to the buildConnectionString() function. If you run it from the command line, it will also run the code after if __name__ == "__main__": This is pretty common - to write a module so it can be imported or used as a main program.

Some choices: 1. Pass the pack as a parameter to the functions that need to use it. 2. Make the pack a class attribute, maybe you can have a Game class. The functions that need it are good candidates for class methods. 3. Make pack a global variable I would start with 1. If you have to pass it to a lot of functions, and the functions seem to cohere into a class, then maybe pick 2. The tipping point between 1 and 2 is a judgement call. I almost never use global variables except for constants and in short throwaway scripts. By the way you may find that a Pack class makes sense, too, with methods like shuffle(), deal(howMany), isEmpty().

It needs to share the variable with the functions (or > methods) in the module not with anything outside of it. It looks like this will be shared and modified. In general, I think read-only variables (initialized at start-up when not constants) can work OK as globals.

I am not sure how the system would respond if we have to get 500 webpages - in the sense the total number of tcp connection is around 500 . Could any body tell me what would be best design ?
