Dear all,
I've stumbled over a problem with Windows Locale ID information and
codepages. I'm writing a Python application that parses a CSV file,
the format of a line in this file is "LCID;Text1;Text2". Each line can
contain a different locale id (LCID) and the text fields contain data
that is

Alas, you've chosen the worst-possible example to "clarify" matters,
because old-style classic classes are *not* unified with types, and will
disappear in the future:
Of course I wanted to write `class A(objec
That would imply that I cannot create instances of a type, only of
a class that implements the type, wouldn't it?
But Python denotes 'int' as a type *and* I can instantiate it.
Now I start getting confused also ;-)
>>> a=5
>>> a.__class__
>>> a.__class__.__class__
>>> dir(a)
['__abs__', '__a
Can someone explain to me the difference between a type and a class?
If your confusion is of a more general nature I suggest reading the
introduction of `Design Patterns' (ISBN-10: 0201633612), under
`Specifying Object Interfaces'.
In short: A type denotes a certain interface, i.e. a set of

Hi,
Sorry I've posted a similar question some weeks ago, but I got no
answers. I want to embed a Python application on a device with limited
resources, esp. storage limitations. Is there a way to reduce the Python
interpreter to a set of modules that's urgently needed? Or is there a
method to

You can execute cleanup code if the interpreter exits:
http://docs.python.org/lib/module-atexit.html
This will only cover the `Python's exit' part of your question, not the
module reloading stuff. On the other hand, if you load a module you
could set a global variable and check for it on reload
Thanks guys, you've helped me very much :) Cheers & happy new year!
