Almost there.
Firstly I would remove the asterisk. Whoever created the intial regular
expression was probably mixing up the shell pattern matching where that
would match 0 or more of any character, but as a regular expression it
means to match 0 or more of the previous character which is a dot. The
intention was probably to allow characters like "rc" (release candidate).
There is no point in matching multiple dots, so just remove it.
There is no need to use that kind of string concatenation, just group
the entire first pattern with parenthesis and the second one too with the
'|' inbetween, like this
r"(\d{1,2}\.\d{1,3}\.\d{1,3})|(\d{1,2}\.\d{1,3})"
Finally note that in the x.y.z pattern the 'z' is the
one most likely to reach 3-digits, I changed it above.
Make sure to test in both your interactive interpreter and finally
in rteval itself.
Thanks!
