There are actually almost too many. Googling for Python IDE will get you a long list of hits to articles.

You could start here: http://stackoverflow.com/questions/81584/what-ide-to-use-for-python

And spend several hours reading some of the other links you will get from Google.

Nikos has shown that you just need to put everything in a single
record. Wow! look at that record with everything in it! Its so cool
and it helped to refrain Nikos the idiot!

Why create a whole new 'downloads' table and associate it with the with
a foreign key with the 'visitors' table you idiot when you can just have
an extra column at the end of the current 'visitor's table?

Both 'downloader' and 'downlaod' is associated by being in the same record.

By your logic every time we want to store an extra piece of information
we have to create an extra database table.

Too much hussle for no good reason....

Go to your local library and pick up a book on database design - or
possibly you'll find it on Wikipedia. There ARE good reasons for the
"hassle" of normalization. There are times when you consciously
denormalize (I often read tables into memory for a (read-only) cache,
and denormalize aggressively), but the rule of thumb is: It's normal
to normalize.

First of all Nikos, you are not qualified to determine if there is
reason to design a database in any particular way, since you don't
understand what a relational database is.
Secondly, in earlier threads I provided you with a link to a wikipedia
article about first normal form and why it is a necessary component of
data base design.
If you don't want to use a database, good for you, but if you can't
get your website to work and you ask for help, then respond that the
help is 'too much hussle', you are disrespectful.
You don't bother me because you are lazy, and arogant, and whiny. Or
that you lack skills. You are a cargo cult programmer. I know you
won't look that up. You bother me because you are disrespectful. The
most disrespectful person I have ever encountered on line.

On a side note to whoever hacks into Nick the idiots website -- why
not just take it down. Then he won't have any need to spend his 20
euros, and there will be no code to fix. Problem solved!

Greece is no more represented by Nikos than any other nations are
represented by their ignorant. When I start to feel ill-will towards
Greece because of Nikos, I also have to remember that the country has
also produced great technologists like Lea Verou and classical art &
philosophy. Then I just wonder why Nikos doesn't take advantage of
the resources his home country provides. :-/

I called you an idiot, because in your previous and current message you
called me too.

I know that splitting information across tables and maintain foreign
keys for retain relationships between them is a necessary thing but in
my case i only just an extra pieces of information to eb associated with
my visitor, a possible file download.

and i have decided just to add an extra colum to the existing 'visitors'
database and this is adequate.

I still don't know why you push me to create an extra table instead.

It may seem that i'm clue resistant sometimes and i'm but this is not
because out of arogance but as a result of failign to under

My rates start at $100/hr and come with the requirement that you
actually listen to what I'm saying. Actually, you'll probably find
that you can skip the $100/hr if you just listen to the advice you've
been given for free on this list, but you asked for a "really good
price", and for this kind of work, I think the price I quoted is
exactly that.

100 bucks per hour? Oh My, i cant afford this at all.
All i can give is 20 euros for the conversions of the script to
framework style.

Its not like you are going to create the script from scratch, you will
just need to modify it in some fashion to make it frameworked because i
don't have the slightest clue how to implement this.

(Please don't start your text with a double-hyphen - that's a common
convention for the start of your signature, and many people and UAs
will ignore text after it.)

20 Euro won't buy you much in the way of programmer time. Most job ads
I've seen are offering at least $50/hr for salaried work, and contract
work will start a lot higher than that. (I don't know how rates are in
Europe, but they'll be roughly in the same ball-park.) Your figure
would buy you maybe half an hour of someone's time... if you're lucky.
Most likely it's not even on anyone's radar. Perhaps now you'll have
some appreciation of how much you get *for nothing* here on this list.

The main point of my post, though, was that if you pay someone to do
your work for you, you WILL have to accept the way s/he does things.
If you get a guy to design you a database for your hit counter and he
does it with two tables, only a crass fool would then say "I don't
care how well you've done that, I'm going to do it MY WAY instead",
because if you really knew better than the person you hired, you would
have done it yourself. (Incidentally, this is exactly why I am no
longer with my former employer. He didn't respect my designs, so now
he's free to do his own.) You need to be willing to accept advice once
you ask for it; otherwise, just do things yourself - and cope with the
legal requirements, which I don't think you've yet even considered,
despite spending all this time on tracking your users and retaining
personal/private information.

It's '-- ', with a space after, to be precise.

To be even more precise, it's those three characters on a line all by itself.

Gmail automatically hides all longer quotes (Google Groups does the
same, so they don't get to see their double-spaced nonsense) AS WELL
AS signatures. Well, world couldn't be more wonderful than Nikos

Bring it on baby!

I like this challenge because it makes me improve on overall python
script security(most of it being securing user input data before
actually perform database queries).

I also understand than in my attempt to get help with my code i provided
"too much of it" which was successfully utilized by the hacker to attack
my website!

You didn't answer me though!
Is the hacker really a female?
And if she is, is she pretty? :)

Even if "she" changes the root password(assuming she's somehow in
control of my VPS), i can easily alter it in some other string of my
liking very easily.

Please try modpy.

That's not going to work, JSON strings must use double quotes, which you've rewritten as single quotes. The correct way (as shown previously) is to wrap the entire string in single quotes, thus preserving the double quotes inside.

hi.

got a test file with the sample content listed below:

the content is one long string, and needs to be split into separate lines

I'm thinking the pattern to split on should be a kind of regex like::
 #45 / 58#0#
or
 #9 / 58#0
but i have no idea how to make this happen!!

if i read the content into a buf -> s

import re
dat = re.compile("what goes here??").split(s)

--i'm not sure what goes in the compile() to get the process to work..

thoughts/comments would be helpful.

thanks

test dat::

almost works..

except i get
m = 10116#000#C S#S#100##001##DAY#Fund of Computing#Barrett,
William#3#MWF #08:00am #08:50am #3718 HBLL
m = 45
m = 58
m = 0
m = 10116#000#C S#S#100##002##DAY#Fund of Computing#Barrett,
William#3#MWF #09:00am #09:50am #3718 HBLL
m = 9
m = 58
m = 0

and what i want is:
m = 10116#000#C S#S#100##001##DAY#Fund of Computing#Barrett,
William#3#MWF #08:00am #08:50am #3718 HBLL 45 / 58,0
m = 10116#000#C S#S#100##002##DAY#Fund of Computing#Barrett,
William#3#MWF #09:00am #09:50am #3718 HBLL 9 / 58,0

so i'd have the results of the "compile/regex process" to be added to
the split lines

thoughts/comments??

thanks

I just starting out and am using the Python For Kids book. I have an 2.4 GHz Intel Core 2 Duo iMac running OS X 10.6.8,
and I'm getting this message when I open IDLE:

Warning: The version of Tcl/Tk (8.5.7) in use may be
unstable. Visit http://www.python.org/download/mac/tcltk/ for current
information.

Not sure how to proceed.
