Re: Help Required for Choosing Programming Language
>- designing the GUI will cost me about 2 .. 3 times as much in Python
No, but if that's your believe ..
Some examples:
- Creating a treeview (like in the M$ explorer), with full edit capabilities and full drag & drop
facilities: Delphi takes about 40 lines of code (most of them even ^C ^V).
- Creating a graphical overview of relations between database tables, which can be graphical
manipulated by the user (like in M$ Access): Delphi 20 lines of code.
I wonder what this costs in Python ?

I'm not sure what you are talking about here, and I have the deep
impression you yourself don't as well.
I'm not an (educated) programmer, so I don't always use the right terms :-(
If I look at a well established program like DIA,
and see that it still can't repaint it's screen always correctly, ...
If I just look at MathPlotLib ;-)
But I also know one beautiful program based on wx: KICAD.
I've been using Python for just 2 months, and didn't try any graphical design,
I've other priorities first.
I would love to see:
- a comparison between wx and gtk (QT doesn't have a very inviting license ;-)
- some Python applications that uses one of these graphical libraries.
To give you an impression of some features I'm after, I've prepared an animation (not completely
ready yet), of the program I've written in Delphi, with both embedded MatLab and embedded Python,
where MatLab or Python does all the real-time numerical analysis.
Writing this program, including teaching myself Python (with a lot of help of this group, thank you
all !!), and writing the bloodpressure analysis in both MatLab and Python, excluding the
ADC-drivers, costed me about 150 .. 200 hours ...
.... can that be done be an experienced programmer in Python.

You mean delphi here I presume?

Matter of factly, there is no "the python GUI". There are quite a few
choices. The built-in tkinter, which - while limited in some senses - is
developed by Frederik Lundh, and while I personally haven't done too
much with it, his reputation as one of the most high profiled python
developers doesn't go along pretty well with your assertions above. So
-whatever you used as GUI-toolkit, you either used it wrong, or it
really wasn't good.

But then there are at least three major other toolkits available, wx,
gtk and Qt. The first two I've only dabbled a bit with and can't comment
on.

But I've done extensive, cross-platform development with Qt. And can
assert that it is unmatched in productivity and feature richness,
especially when combined with python. And certainly beat VB, and most
probably even delphi (albeit I haven't done too much in that to really
put all my weight behind these words).

And so I'm under the strong impression that your - undoubtedly correct
from a personal point of view, and I don't think your meaning evil here
- observations are wrong and are based on a lack of experience in python
and it's available gui-options.
