[Tutor] quick OO pointer

[shawn bright]

Hello there,a while back i wrote a module called DbConnector.py that allowed me to run different types of SQL queries. Cool enough.i did it mostly to handle the open and close of a db connection so i wouldn't have to worry about 'too many connection' errors.
it makes a connection, runs a query, then closes the connection. The reason i write this, is that i know how the module works to make a connection 'object'now, i have a few functions in some scripts that i would like to reuse across the board. But, they dont really fit the "object" thing, i dont thing. Basically, i have a bunch of functions that do different things and i would like one script to hold them all.
do i need to define a class for this, or can you import a function from another script ?like if i have def write_something_to_log(logfile, something)    f = open(logfile, 'a')    f.write('%s\n' % something)
    f.close()    return 'success'and i wanted to use this same function in about four different scripts, do i need a class ? Do i need to just create a script full of common functions that i can access ? and if so, how ? 
usually in the tutorials i read, they deal with OO and classes. Most commonly a class called Person. Then person has different attributes. But these functions are just bits of code that i want to reusewhat is the cleanest way to do something like this ?
thankssk

Have been doing some googling myself..The Selenium tool looks good. It
appears to be a record-and-play extension to the firefox
browser...Anyone have any experience with the Selnium Remote Control?
I'm having difficulty installing it.

All the stuff you need is right here:

Specifically, the clicking buttons part is in ClientForm.

Hi Hans,
I'm sure its possible, though i haven't a clue how you'd go about doing
it. If its just for testing and you don't need it integrated with
python, you might want to check out Greasemonkey
(http://greasemonkey.mozdev.org/) or Chickenfoot
(http://groups.csail.mit.edu/uid/chickenfoot/) which make those kinds of
tasks absurdly easy.

[Tutor] Python for basic web-testing

[Hans Dushanthakumar]

Hi,
   How do I use python for basic web-tasks 
like inputting data or clicking buttons on web-pages. For eg, how do I enter my 
username and password and click on the "OK" button on the yahoo mail 
page?
I had 
a look at the webbrowser module documentation (http://www.python.org/doc/current/lib/module-webbrowser.html), 
but it doesnt seem to support clicking buttons or sending 
data.
Thanks,
Hans

[Tutor] Community documentation framework?

[Bob Nienhuis]

Have you had the experience of finding a nifty bit of code on the
web, trying it out, and then discovering that technique
only worked in version X.YY, or requires module Z that
is no longer available?

Well perhaps we can address this situation.

I would like to see an online system that facilitates
the collaborative production, cataloging and updating of 
community documentation. See an article, "Rethinking Community 
Documentation" by Andy Oram 
.

Features I would like to see:
    A Wikipedia-like capacity for community update-ability/modifiability
    of documentation submissions.

    Database for cataloging available packages, modules, FAQs, How-Tos
    tutorials, cookbook code fragments etc. Should have capacity for 
    developers to add and others to add to their contributions. 

    Oram suggests a rating system for submissions so users can assess
    the quality of submissions, and point to parts that need modification
    or clarification..

    Might use TurboGears, Django AJAX or other web framework?

I think main Python documentation is great, but there is a lot
of stuff out there that isn't documented so well, or needs
updating. This project is intended to adress that need.

What would you like to see?

Hi Anil,

Anil, take a look at:

 http://www.python.org/doc/lib/typesseq-strings.html

Does this address your question?


On a high-level view of your questions so far:  Are you running into 
problems because you can't find the documentation?  Or is the issue that 
the documentation is unclear?

Hi Anil,

Are you taking some kind of internet web-development class?  You seem to 
be asking a lot of web-development questions.  In the absence of context, 
I'm not sure what to do other than to point you to the standard RFC on 
Uniform Resource Locators:

 http://www.faqs.org/rfcs/rfc1738.html

and see if that addresses your question.

Re: [Tutor] can you explain string replacement syntax and commaseparated statements

[Alan Gauld]

> can you explain string replacement syntax and commaseparated 
> statements

string substitution replaces the 5 %s comvbinations with the 5
values after the % sign

A simplied example is:

s = "hello %s, welcome to %s" % ('world','python')

Your example just uses triple quotes to allow the string
to wrap and has more substitutions. The 5 values are also
less direct but all yield strings eventually!

The comma separated assignment looks like a mistake to me!
A simplified form looks like:

s = "Hello", s += "world"

Which yields a syntax error.
Are you sure its not a semi-colon, in which case it just combines
the two instructions on a single line.

If so its very bad coding style IMHO but is legal.

HTH,

Re: [Tutor] how to use

[Alan Gauld]

Hi Anil,

Are you reading a tutorial?
Most of the questions you are asking should be covered
in any standard tutorial.

> what does
>
> x**x) do?

Its equivalent to

pow(x,x)
ie raises x to the power x.

> 2nd) what is the key for the dictionary, i assume x is the value of 
> the dictionary

> dict((x, x**x) for x in range(10))

x is the key and x**x is the value.

[Tutor] Raw files and jpeg thumbnail extraction

[Richard Querin]

I am interested in extracting jpeg thumbnails that are stored in my camera's Canon .CR2 raw files. Does anybody know of any python libraries with this kind of functionality? Is dcraw the only way to implement this functionality? I'm writing a simple gui to selectively process raw files into jpegs, but I really would like to pick the photos based on thumbnails. I read somewhere that most digital camera raw files contain jpeg thumbnails that would be much quicker to load than doing an on-the-fly conversion just to get the thumbnails. 
Can anybody point me in a good direction on this?

Re: [Tutor] This will run on Outlook but not Outlook Express

[Alan Gauld]

> from win32com.client import Dispatch
> s=Dispatch("Mapi.Session")

I don't think Outlook express uses MAPI.
MAPI is a strictly Microsoft protocol and only used in Outlook 
and a few other clients that try to talk to Exchange servers.

Outlook Express is a much more conventional mailtool 
that talks POP/SMTP (and maybe IMAP?)

> I was wondering if I could write a script that would run on

Trying to use a COM object model for that will be extemely difficult.
I'd look at using the standard email tools with Python since both 
Outlook and OE talk standard internet mail protocols.

You can override the web.internalerror function to have it to do other  interesting things.
