Hi folks,
I want to develop an application which uses a database and some forms to
enter/modify the database.
The application should also generate reports based on some fields.
What should I be using? Python or VB...
I want to use Python.. IN that case, what should be my choice for the
Database
Hi,
I'm really confused, and I hope somebody can explain this for me...
I've been playing with compression and archives, and have some .zip,
.tar, .gz and .tgz example files to test my code on.
I can read them using either zipfile, tarfile, gzip or zlib, and that's
fine. But just reading them in

Oh... of course. Thanks and sorry for missing the bleeding obvious.
Mind you, when reading in 'txt mode' rather than binary, len() actually
gives a much *smaller* size than getsize. Does the conversion into txt
happen to introduce some sort of terminator character that stops
file.read() from going

That is both a religious question, and fighting words

Melted my life, got a divorce, gutted the house, acquired true love, 2
cats, redid house, new job, and dentures. Let's see, I still need a
total blood change-out, but other than that, I did it all.
Now I can start paying attention to python and wiki's again.
And this is good, because
Thanks a lot for the support...

lo there all,
i am reading a binary file with open('myfile', 'rb')
then i do a read(1) to read one byte. cool so far.
but how do i read the individual bits of a byte
i mean if i have a = read(1)
how do i know what the msb of a is ?
i need to know because i have to see if the msb is set and i

Hello Tutors,
I'm trying to get a grip on MULTILINE and I guess I don't have it.
Here's some code:
#!/usr/bin/env python
import re
def sub_it(mo):
return 'xxx'
def test(re_str, data):
return re.sub(re_str, sub_it, data, re.MULTILINE)
if __name__ == '__main__':
data = '''Be
Hi,
I have compressed files compressed using different techniques (especially
unix compress). So I want to have a module that reads any of these
(.Z,.bz,.tgz files) files and manipulates the data.
The data has a syntax.It contains
HEADER (some information)
BODY (some information)

I've been working on a version of a script I found in

List comprehensions were implemented in v2.0. The OP probably does not
use an older version, but as far as I can see, his syntax error line
uses parenthesis -
great, thanks for this. appreciate it a lot.

I was surprised to be unable to find a function in Python for
converting ints from base10 to base2. Is there one?
I wrote one, but have I reinvented the wheel again? (Even if I have,
it was an interesting exercise for me.)
I know some of you CS people won't like what I do with negative ints,

I suspect the function I sent out earlier, using octal conversion and
a lookup table, will be faster. But it would be very interesting to
see some simple benchmarks.

ok, getting back to python and wikiness, I have a problem, this software

python (2.5) than under the version used when I first wrote it (2.3).
