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 w

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 Windows.
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

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

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.

There are several template-engines where you more or less include
python-code into the template, e.g.: empy, mako,

you can -- MIT/BSD/public domain etc. provide much more freedom to the

hmm, I don't think so. I've build several applications in C + GTK/Glade and

changes.

You can use psyco.
The following example should be about 4-times as fast as your example:

psyco.full()
def f():
imax = 10
a = 0
for i in xrange(imax):
a += 10
print a
f()

It's a short illustration; 0 .__class__ itself is harmless, but e.g.

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__
