Hello,
This might be slightly OT, but I hope I can get a few pointers. Is it
possible to have an HTML form pass values to a Python script on a local
computer, and execute that script? (I'm running Win XP, if that matters.)
I would like to set up such a form to do some data entry. I understand

Hi Mark,
In my brief experience with OOP, I would say that the main advantage is
organization of code. All functions and attributes that you need to work
with an object are wrapped up nicely inside the object. Also, object
inheritance provides a great framework for easy customization.

Hi,
I'm trying to use Beautiful Soup to scrape some data out of an HTML
table. I can do this using
table = soup("td", {'class' : 'yfnc_tabledata1' })
table[0].string.strip()
However, if I try
for entry in table:
entry.string.strip()
I get: AttributeError: Tag instance has no attribute 'string
Hi Kent,
First off, thank you so much for the suggestions! They have helped
clarify some of the concepts I've been struggling with lately ( mostly
object - related ones ). I have been teaching myself Python in my spare
time for the last few months, and have no previous programming
experience,
Hello,
So I think that I've 'completed' my first real Python program, and I
would appreciate any constructive criticism you all could offer. The
program deals with a question that my Dad asked me awhile ago, which was

This article might also be helpful, as it is a little more concrete:

'python database access object'. Is this the kind of thing that you are
referring to, Kent?
HTH,

Liam,
I think what you want is called a view. A view is a memory based table
defined by a query as follows:
CREATE VIEW myview (
column1,
column2,
... )
AS
BEGIN
SELECT * FROM table1
END;
In this example, you can now SELECT * FROM myview, and get table1. You
can put joined tables or

I'm using Kinterbasdb to access a Firebird database through Python, and

I also recommend learning SQL. It is not very hard to learn, and
sometimes it may be advantageous to do data manipulation directly in the
database, rather than with Python. As far as databases go, I would
recommend Firebird, as I have found that it has a good number of
features, is free, and
Hello,
I'm trying to have a loop in a program print a message so I know it's
status. Right now I'm using
print "Percent completed:" + str(percent) + "\r"
Which should send me back to the beginning of the line and overwrite it
with a new line. But instead I get:

There has been alot of talk on this list about using list comprehensions
lately, and this could be one of those useful places. While I don't
have time to experiment with real code, I would suggest changing your
function to look like:
steps = [ min_x + i*delta_x for i in range(steps) ]

Hello,
I have a list of lists, for example [ [1,2] , [3,4] ], and I would like
to pass all the elements of that list as arguments to a function (for
example the intersection of all list elements). Is there a command in
regular Python to do this? I would like to avoid the hassle and speed

You might want to try:

this will return true if, for example, list = [x,y,z,w], false if list

OK simple query,
I have a list consisting of about 250 items, I need to know if a

Is there a module containing a function for listing the unique k-element
subsets of an n-item list? I have written some code (right now I only
need it for 2 element subsets):
