AFAIUI, it's not possible to say "2.8+" == "2.8 and all the higher
versions", but we can specify a list of version to be searched, the
first match is the one "mapped" as default wx. If no-one of the
specified version are available, then an exception is thrown:

>>> import wxversion
>>> wxversion.select(['2.5','2.3','2.9'])
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.5/site-packages/wxversion.py", line 149, in select
    raise VersionError("Requested version of wxPython not found")
wxversion.VersionError: Requested version of wxPython not found
>>> wxversion.select(['2.5','2.3','2.8'])
>>> import wx
>>> wx.__version__
'2.8.7.1'

In any case, the example code doesn't work with wx2.6 so, as even a
temporary workaround, I think we should enforce the needs for wx2.8.

Sounds good to me, but I am not a wx user, so I might be missing 
something.  The only reservation that occurs to me is this:  suppose 
version 2.10 comes out, and someone has only that installed.  Is there a 
way to select 2.8 or higher, instead of requiring 2.8?

Moreover, I will provide a patch to move from

>>> from wx import *

to

>>> import wx

that's much more clear. Just let me know if in the patch I will add
the wxversion.select or no.

Hello,
we are facing a problem in Debian where a user has problems running
embedding_in_wx*.py examples.

The problem is:

>>> from wx import *
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute '__DocFilter'
>>> import wx
>>> print wx.__version__
2.6.3.2

Since WX2.8 is the one to use, the solution is simple:

>>> import wxversion
>>> wxversion.select('2.8')
>>> from wx import *
>>> wx.__version__
'2.8.7.1'

That solves the problem of multi-wx on a system.

What do you think about adding those 2 line into wx examples?

Regards,
