Bug in re module?

[Ant]

Look at the following minimal example:
('Test', 'String')

I would have expected this to produce:

('String')

since ?...) should be a non-capturing group. From the module
reference:

(?:...)
A non-grouping version of regular parentheses. Matches whatever
regular expression is inside the parentheses, but the substring matched
by the group cannot be retrieved after performing a match or referenced
later in the pattern.

Look at the following minimal example:

.... (snip example that shows non-capturing group capturing)

Note I get the same results from python versions 2.4 and 2.5.

Try ?: instead of :?

(?:...) isn't the same thing as ?...), though.

Look at the following minimal example:

Bzzzzzt! Sorry, PBKAC.

The correct syntax is (?:foo)
You have ?foo)
which matches an optional colon followed by foo.

Don't know what I was thinking that something as high profile as that
could slip through the net!!
