Subject: Add re.VERBOSE flag documentation example (#97678)
X-Git-Tag: v3.12.0a1~250
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=0ceafa7fa408b64377ea31dd5386152da19ef38a;p=thirdparty%2FPython%2Fcpython.git

Add re.VERBOSE flag documentation example (#97678)

The current re.VERBOSE documentation example leaves space for ambiguous
interpretation. One may read that spaces within the `(?:` token are
spaces inside the non-capturing group (such as `(?: )`). This patch
removes the ambiguity by including examples after the statement.
