programmatically change windows regional settings?

[Albert-Jan Roskam]

Hi,

In Windows I can change the regional settings manually in the control panel. But how do I do this programmatically? I tried setting LANG but this does not work in Windows.

Kernel32's SetLocaleInfo sounds promising, but "This setting only affects the user override portion of the locale settings; it does not set the system defaults." https://msdn.microsoft.com/en-us/library/ee491893(v=winembedded.60).aspx

Another route might be _winreg (but that's probably more brittle and, more importantly, the registry sucks)

My goal is to easily run my unittests in a number of locales (actually a platform x locale x python version matrix)

Thanks!

Albert-Jan

You're probably better off asking this on
https://mail.python.org/mailman/listinfo/python-win32 which is also
available as gmane.comp.python.windows, although you might get lucky
here. If you do a rather more specific statement than "this does not
work in Windows" would be helpful. Your Python and Windows version(s)
might possibly assist as well :)

Ok, I'll check that out, thanks. Hope that list is about more than win32com

One can set LANG in Windows (of course), but Windows does not appear to ever use it. So it's pointless.
setx LANG France.French.1252 && python -c "from locale import *; setlocale(LC_ALL, ''); print(getlocale())"

... Does not print a French locale on my non-French system

Windows Server 2012 R2 (x64), and preferably also Win 7 x64. Python 2.7, 3.3, 3.4, and ideally also pypy.

I actually think he will get the best advice from the testing-in-python
mailing list.

:-) That's indeed what I've done initially, but my message does not get posted. But maybe that list is moderated and I'm too impatient. But TIP is indeed the place to be for Tox-related questions.

From the above link "All issues related to programming Python on
Windows. win32 extensions, COM, you name it."

How Great to Hear! <cheer cheer cheer>

But I wonder how much of that has to do with changing division?

OpenEnd (my company) makes bookkeeping systems for Swedish Ideal
Societies (closest English words 'non-profits' and 'clubs'). A
surprising number of our potential customers are relying on code
written more than 20 years ago, by somebody who is no longer part of
the Society which used floats for arithmetic. Hard to make the sale
when the customer thinks your math is broken. So I am biased, but in
my little corner of the world, Float Confusion Reigns Supreme.

I didn't know about that one.
Hey thank you, Mark. Looks great.

It needs its own entry in
https://wiki.python.org/moin/PythonTestingToolsTaxonomy

You add it, or me?

Laura

[Mark Lawrence]

Thanks all the same but I'll leave it to you, as I suspect I'd be my
usual combination of headless chicken and bull in a china shop if let
loose on a wiki :)

[Laura Creighton]

Ah, turns out there was an entry. I updated it.

Note that some people I know of, via webmaster, found that they
could install 3.4.x with the ActiveState installer but not the python.org
one. Apparantly ActiveState bundles up some DLLs in its installer
'in case the user doesn't have them' whereas we don't -- and turns out
some users don't have them. I have never been able to get enough out
of a user to find out exactly what magic sauce they have that we do
not -- it would be really nice to find out so that we can add it too.

No guarantees that this particular user has this particular problem,
of course.

He's sending us that stuff, but he may be writing it someplace else
first. And that someplace else may be spitting out combined
spaces and tabs. If he is pasting that into the interpreter,
that will cause tons of problems like he is seeing.

At 18:33 BST Simon stated "I typed in (and did not copy and paste) the
