Hi,
I've got some kind of install problem with jpype ... It should just
work, but throws a dialog exception, that doesn't give a stack trace
so not very helpful.
This should be a simple install issue, but I've searched and haven't
seen any thing
import jpype
p = jpype.getDefaultJVMPath()

In Python such list cell isn't empty, it's absent. So you can use
len(somelist) to see how much long the list is before accessing its
items. Often you can iterate on the list with a for, so you don't need
to care of

Hi, Bernard.
Just tried the first 2 commands on win XP, Python 2.5 under Idle.
An Error is raised: "unsupported locale setting" (lib/locale.py in
setlocale, line 476).
Actually I get the error also under Python 2.4.3
Any idea what I'm missing?
Thanks in advance.

Hi!
``num`` must be an iterable object (tuple, list, ...).
num = (200,)
cur.execute("INSERT INTO foo (id) VALUES (?)", num)

Yes, I am sure about those things.
I've tried shutil.move and got the same result.
Forward slash? I'll give that a try and report back here if it works.
Thanks,

Are you sure the source directory exists and you
have rights to rename it? Because the rename works
for me.
But you may want to look at shutil.move and/or
use forward slashes (they work under Windows)

I'm having a problem using a path with spaces as a parameter to
os.rename() in a program on WinXP.
This works fine at the command line (where the folder "c:\aa bb" exists)

But, I can't get it to work in my program, eg.
print SrcDir

Thank you all for your replies. The repr() solution wasn't exactly what
I was looking for, as I wasn't planning on eval()ing it, but the
(en|de)code solution was exactly what I was looking for. An extended
thanks to Jp for informing me of the version compatibility :)
Have a GREAT day :)

In [2]: s.encode("string_escape")
Out[2]: 'foo\\n\\xfe'
In [3]: repr(s)[1:-1]
