alternatives to match your platform or functionality requirements.

Alternatively you just write your code against one spreadsheet module,
and then write a wrapper module for the other spreadsheet API so it
looks the same.

You could try and find out what the __load statement in line 10 in

There are no prebuilt Python modules available based on quickfix, at
least that I'm aware of. It has Python bindings available, but you
have to complie it
it. Qt provides them with a platform with the potential to
rival the iPhone dev environment.
Of course to take full advantage of it you need to invest in learning
it all, which is non-trivial. It comes at a cost in time and potential
lock-in. But the point is you can't just say
t all others
are measured, and generaly found wanting.

I wouldn't completely dismiss Tkinter. It's too simple for complex

One thing to look out for is that 'columns' is being created each time

How can I convert a PIL image into a buffer object? I can't find any

The only fly in the ointment in licensing. The QT toolkit will be
fully GPL and LGPL from version 4.4, but PyQT itself has a dual GPL/
commercial licensing structure. Still, it's relatively cheap and well
worth it
Great contributions, thanks both of you. I'm self-tought when it comes

You'll need to import numpy and Image. You'll need to generate the
palette (juust a list) and image array (a numpy array) of course.

there's a module for this. Those kinds of tests are
fairly easy though.
import datetime, os
filename = 'myfile.log'
if (datetime.date.today().weekday() == 0) or (os.stat(filename)[6] >
200):
do.whatever()
The individual tests would be better wrapped in utility fu
ercial or the express version, to create the
GUI in VB or C# and from that call Python code that does all the heavy
lifting.
I'd second the recommendation for QtDesigner if you want cross-
platform capability.

Having said all that, Python isn't magic. I'd recommend doing something
simple first, such as a calculator or a text editor. These are very
easy to do, but will cover the basics of creating a user interface,
manipulating data and accessing files.

I'd say that Python is easier to learn and more productive as a
language, but Java has a much larger selection of add-ons and libraries
available. I can't give you much more help without knowing what the app
will do, and therefore what language features or library/framework
would be useful or appropriate?
