Regex and python match

Question

Hello all and sorry to bother with another regex question... This time the problem I have is that I'm unable to match or exclude some strings out of a regexp:

Strings to compare against:

EVENT DATA
EVENT
EVENT SEC-1193 10222
EVENT META

I want this regex to match only EVENT SEC-1193 10222 and it's like this:

EVENT\s[\w'-]*\s[\w'-]*

The problem is that it matches everything... Any help in the reghell would be highly appreciated

Answer 1

EVENT\s[\w'-]+\s[0-9]+

Seems to be a bit better. Try testing your regex's with http://gskinner.com/RegExr/ or http://regex101.com/

Answer 2

Use + instead of *:

>>> r = re.compile(r"EVENT\s[\w'-]+\s[\w'-]+")
>>> r.search("EVENT DATA")
>>> r.search("EVENT")
>>> r.search("EVENT SEC-1193 10222")
<_sre.SRE_Match object at 0x8e04100>
>>> r.search("EVENT META")
