Well, assuming you pass in the UNICODE or LOCALE specifier, the
following portion of a regexp *should* find what you're describing:
###############################################
import re
tests = [("1", False),
("a", True),
("Hello", True),
("2bad", False),
("bad1", False),
("a c", False)
]
r = re.compile(r'^(?:(?=\w)[^\d_])*$')
for test, expected_result in tests:
if r.match(test):
passed = expected_result
else:
passed = not expected_result
print "[%s] expected [%s] passed [%s]" % (
test, expected_result, passed)
###############################################
That looks for a "word" character ("\w") but doesn't swallow it
("(?=...)"), and then asserts that the character is not ("^") a
digit ("\d") or an underscore. It looks for any number of "these
things" ("(?:...)*"), which you can tweak to your own taste.
For Unicode-ification, just pass the re.UNICODE parameter to
compile().
Hope this makes sense and helps,
