In a manner of speaking, that's correct.  You'll get a basic default
initialization (and inherit the __init__() from your superclass(es) if
your new class is derived from another one.

You just create  your own __init__() if you have something you need to
set up, and/or need to call the superclass __init__() in a special way.

[Tutor] Confirmation about __init__()

2010-01-16 Thread Robert
I have read quite a bit in the past 2 months, ( I have also looked at codes)
At this point, I think I understand well what __init__() is and does -
But, I have yet to see this *specifically* spelled out about the the
__init__ method for a Class;

It is OPTIONAL, correct ?

if I have NO start values/variables to set, no Base Class __init__ to
call --- the __init__ method is NOT required, correct ?

thanks

This is one of the biggest barriers to adopting Python 3. Until PIL 
gets ported it's a non starter for many folks.


And why Tk doesn't support formats other than GIF and PPM for 
its "PhotoImage" widget is a long standing mystery! Thee has been 
much talk of supporting JPG but nothing has ever materialised.

[Tutor] Images on Python 3k

2010-01-16 Thread Luhmann
Hello List,

Does anyone know of a way simple way to display JPG and PNG images on python 3?

My program uses tkinter, and currently my solution is to use ImageMagick's 
convert through std to convert the images to gif. However the conversion is too 
time consuming.

I have only started using python after Py3 was released, so this is is the only 
version I know. I have tried to make my code work in Python 2 so I could use 
PIL, but I
came across many bugs to which I could not readily find a solution, and it 
seems it would take me a long time to get it fixed.
