Hi,
after reading the mails of this thread, I would recommend one of the
following ways:
1. Use a computer-readable format and some small editor for humans.
The file-format could then be very simple -- I would recommend JSON.
Or some kind of database (e.g. SQLite).
For humans, you

Hi,
the two "big" GUI toolkits on Linux are GTK+ and Qt.
Both are free, have Python bindings and a graphical GUI designer, and both
have ports for Windows and Mac OS X. Qt does have a better cross-platform-
support and supports more platforms, but GTK+3 also works for Linux, Mac
OS X and
Hi,
I would recommend to use Pylint (http://www.pylint.org/) in addition
to pyflakes. Pylint is much more powerful than pyflakes, and largely
configurable.

Hi,
But how then do I separate out the logic and the GUI?
I usually write a library (C library, Python module, ...) which contains
the logic.
Then, I write a GUI (in a separate file), which imports and uses the library.
If I need another UI (e.g. GUI with an other toolkit, or a text-based or

These days, GUI programming is to me just
programming and calling on certain libraries/modules.

One thing you may want to consider is using your main thread for the
UI, and spinning off another thread to do your search. But do that
ONLY if you know you understand threads, and

In Python 2.6 it wasn't internal to iterencode; in Python 2.7 and 3.x
you probably would have to monkey-patch iterencode.

Please read the original post before answering. What you suggested does not

Hi,
Well all previous (python 2) code is meant to work for a tab size of

yes, but even in Python 2, mixing spaces and tabs is considered bad
style and should be avoided. And code-checkers like pylint (which I
can recommend to everyone) create a warning.
You may call this categorically

Hi,
How so? It's LGPL. You can't get much freer than that.
you can -- MIT/BSD/public domain etc. provide much more freedom to the

Hi,
That way of building a window tends to produce programs that port
badly to other systems.
hmm, I don't think so. I've build several applications in C + GTK/Glade and
Python + GTK/Glade, which easily run on Linux and Windows without any GUI
changes.

Hi,
I agree that on Linux GTK is pretty darn slick. I use it for all my
little GUIs. But on Windows, GTK, particularly under python, isn't
quite as easy to get running.

for windows on http://www.gtk.org (for GTK+) and

[q] In Qt, it's also possible to generate such flexible layouts. But
it's unfortunately not the default way in Qt, and the Qt designer only
supports it rudimentarily, and in a much less obvious way. And Qt does

In Qt Designer (at least in 4.x), the default is a fixed layout, where

Are there any ways to speed up the for/xrange loop?
You can use psyco.
The following example should be about 4-times as fast as your example:

a = 0
for i in xrange(imax):
a += 10
print a

Hi,
many Python-modules contain metadata-variables, like __author__ etc.
But most documentation-tools only support some of these variables, and
some tools even define their own metadata-variables.
So far, I found:
- pydoc (- pydoc.py):
__author__
__credits__
__date__
__version__
