Hi,
I would like to know if 1)there is a Python way to tell under which
terminal process a Python command-line application is running 2)there
is a Python way to tell the OS to give focus to another window.
Solutions for Windows, Linux and OS X are welcome, even if OS-specific

Thanks to everyone in this thread. As always on this newsgroup, I
learned very much.
I'm also quite embarrassed of my ignorance. Only excuse I have is that
I learned programming and Python by myself, with no formal (or
informal) education in programming. So, I am often clumsy.

Hi,
I'm struggling to use the python in-built csv module, and I must say
I'm less than satisfied. Apart from being rather poorly documented, I
find it especially cumbersome to use, and also rather limited. What I
dislike more is that it seems working by *rows* instead than by
*columns*.
So I

Hi Guilhermo,
I have not an actual problem. I'm just trying to use the CSV module
and I mostly can get it working. I just think its interface is much
less than perfect. I'd

Ok, this is not straightforward at all.

small classes that become inherited by

I don't know if it's true, however. I tried that:

The new-style behaviour only appears when wxFrame is plugged with the

That is:
- print type(self) in wxFrame alone returns type 'instance'

Now I'm even more confused. The self-contained example is below... and
it works, using only old-style declarations.

Uh, oh.
I think I found the bug, and it was a *really stupid bug*.
The list of GUI_PLUGINS was empty... so there was no plugin class that
was inherited.
I'm embarrassed to have wasted your time that way. However I learned a

No, it removes the association between the name 'item' and the object it is
currently bound to. In CPython, removing the last such reference will
cause the object to be gc'ed. In other implementations, actual deletion
may occur later. You probably should close the files directly and arrange
Hi,
Python 2.4, Kubuntu 6.06. I'm no professional programmer (I am a ph.d.
student in biophysics) but I have a fair knowledge of Python.
I have a for loop that looks like the following :
for item in long_list:
foo(item)
def foo(item):
item.create_blah() #--this creates item.blah;
It will delete the *name* `item`. It does nothing to the object that was
bound to that name. If the name was the only reference to that object, it
may be garbage collected sooner or later. Read the documentation for the
`__del__()` method for more details and why implementing such a method
Relying on the `__del__()` method isn't a good idea because there are no
really hard guaranties by the language if and when it will be called.
Ok, I read the __del__() docs and I understand using it is not a good
idea.
I can easily add a close_files() method that forces all dangling files

Isn't the very concept of major releases (1.x, 2.x, 3.x) that they
*can* be not backwards-compatible with previous releases?
