Hi,
I'm planning to learn a language for 'client' software. Until now, i
'speak' only some web based languages, like php. As a kid i programmed
in Basic (CP/M, good old days :'-) ) Now i want to start to learn a
(for me) new computer language.
I like Python. Its free, easy to learn and some favorite programs of my
are written in Python / can understand Python (like OpenOffice) etc.
But I'm not a full-time programmer. I know, that I've only time &
possibility to learn one (= 1) language good. So i ask myself is python
the language I'm looking for?
In the future, i want to write the following applications:[*] A database driven program, which can handle my clients, tasks and
places (= 3 tables, has to work relative with each other). I think,
this isn't a problem for Python[*] As a photographer i like to build a picture management system (also
db) with raw support. Raw is the raw-data from the sensor of the
camera. My questions:
- can python encode raw?
- can python head for a utility like dcraw?
- or head for a utility like IrfanView (delphi?) or something like
that?
Tnx for your help!

As stated above python is capable of all those things, however on
larger applications like that it can tend to slow down a bit. And the
executables do need a little bit of work, because it's bassicly a dll
and a library of all your .pyc files. However python is still a great
language and I would recomend it. And most of these things will
probably be fixed in Python 3000!

Yes.
Yes, Python is generally capable in all the roles you describe.
Perhaps most exciting, though, is that you can try out the
language yourself, TODAY, over the next few hours, and, in no
more time than that, get a realistic if limited idea how it's
likely to work for you. With the right introduction <URL:
http://docs.python.org/tut/ you can be coding usefully in
Python very quickly.

Yep! Python is very much a jack-of-all-trades language. I've used it
for similar tasks, including as a front-end for dcraw (I have a little
python script to slurp images from a camera with dcraw and convert them
all to JPEG).
Python has excellent libraries for image manipulation (for example
Python Imaging Library) and for abstracting an SQL database to an
object-oriented form that makes it a snap to work with (I love
SQLAlchemy).
You can learn Python really fast, and it sort of guides you in the
right direction by providing a correct way to do almost everything
without constraining you, so that your code will be consistent and
readable. This, in my opinion, is Python's chief advantage over Perl,
which is the other highly popular dynamic jack-of-all-trades language.
I learned Perl about 10 years ago and loved it for a while, but it's
messy as heck and I find my own code from a few months ago nearly
unreadable... I also spend a lot more time debugging Perl code because
there are so many error-prone things that are silenty allowed rather
than flagged as errors.
I've been using Python for several months and it's just great for
everything. I think it's an ideal first or only programming language!
I've had no reason to write a program in anything else since learning
Python, and I write a LOT of little throwaway programs.

I'll run the risk of being nitpicky, but the full phrase is "Jack of all
trades, master of none," which doesn't do Python justice. Python is a
master of all trades!
But I agree with Dan's sentiment, Python is definitely the language
you're looking for.

Tnx everyone for your response! It's just for me a big step to learn a
new language. Not because of the difficulty, but because of the time
and so.
Later, i remembered that Gimp can also work with python (scripts). So,
even for my second wish, there will be somewhere, somehow a way to do
it.
At least: i use the dutch portal http://python.startpagina.nl/ to start
with. Can you advice me a good Python interpreter, or a good startpage
(as in Python for dummys)?

Can you define 'large'? Is that large in code, or large in database? I
don't know which database is supported. If its a external db, like
MySql, the query is performed through the software of MySql, am I
right? If I'm correct, the 'slowness' comes from the amount of code in
python itself, not from the database.
Not to be picky, but any slowness in software is rarely because of code
size. Rather, it is the data size and algorithms that play the major
role. Only after you got the first two right is that you should worry
about implementation speed.
That said, you are correct. Only if you intend to do *heavy* processing
of the returned data, your major bottleneck should be the database.
*If* you find Python to be slow(for some specific operation, never for
a whole application), you could always rewrite that section using
another language (C/C++ come to mind), or call external libraries to do
the heavy-lifting. The easy integration between Python and C (compared
to a couple other popular platforms) is what drove me to Python.
Make it work first. Then optimize. And Python helps both.

FYI that's only *one* version of 'the full phrase'. I, for instance, am
a 'Jack of all trades, master of many'. I regard Python in the same
light ;-).
