I've just tried this in a Windows machine (with Spanish language) and this
seems to work for me (using WinXP with SP1, I think):
C:\Documents and Settings\Francesc\Escritorio\pytables-1.3\std-1.3>python
Python 2.3.3 (#51, Dec 18 2003, 20:22:39) [MSC v.1200 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import tables
>>> f=tables.openFile('../../Escritorio/hola.h5', 'w')
>>> f.createGroup('/', 'hola')
/hola (Group) ''
children := []
>>> f.root.hola
/hola (Group) ''
children := []
>>>
Also, I've double checked that os.access is working properly:
C:\Documents and Settings\Francesc\Escritorio\pytables-1.3>python
Python 2.3.3 (#51, Dec 18 2003, 20:22:39) [MSC v.1200 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.access('..\..\Escritorio', os.W_OK)
True
>>>
So everything is working well here. Mmm... perhaps a bug in French Win? That's
very bizarre indeed.
Cheers,
