Help with Regexp, \b
This is a bit embarassing, but I seem to be misunderstanding how \b works in regexps. Please can someone explain why the following fails: from re import compile p = compile(r'\bword\b') m = p.match(' word ') assert m My understanding is that \b matches a space at the sta... 31 May 2010 20:46
