regular expression unicode character class trouble

[Diez B. Roggisch]

Hi,

I need in a unicode-environment the character-class

set("\w") - set("[0-9]")

or aplha w/o num. Any ideas how to create that? And what performance
implications do I have to fear? I mean I guess that the characterclasse s
aren't implementet as sets, but as comparison-function that compares a
value with certain well-defined ranges.

Regards,

Diez

I'd use something like r"[^_\d\W]", that is, all things that are neither
underscores, digits or non-alphas. In action:

py> re.findall(r'[^_\d\W]+', '42badger100x__ xxA1BC')
['badger', 'x', 'xxA', 'BC']

HTH,
