[Python-bugs-list] Module re bug. \b fails (PR#230)

[fdrake@acm.org]

Ken reported:

  I thought about that, but it *still* doesn't work:

>>> import re
>>> print re.match("\bchar\b", "  char ")
None
>>> print re.match(r"\bchar\b", "  char ")
None

  So not only is there a bug in the bug report, but somewhere in pcre
(or the Python binding) as well.
