New submission from Wellington Fan:
Hello,
It seems that the word boundary sequence -- r'\b' -- is not behaving as
expected using re.split(). The regex docs say:
\b Matches the empty string, but only at the start or end of a word.
My (failing) test:
> import re
> re.split(r'\b', 'A funky string')
['A funky string']
We get a one-element array returned; I would expect a seven-element array:
['', 'A', ' ', 'funky', ' ', 'string', '']
I have equivalent code in PHP that *does* work:
php > print_r( preg_split('/\b/', 'A funny string') );
Array
(
[0] =>
[1] => A
[2] =>
[3] => funny
[4] =>
[5] => string
[6] =>
)
