[Tutor] Regex

[P L]

Super, re.search(r"ERROR.*?) \(",s).group(1) was exactly what I was looking for.

Thanks again, apologies for not making it clear!

Cheers

Well, if the sentence is guaranteed to be followed by a space and an
opening parenthesis you can use that as the "terminator":

 >>> s = "Jan 31 01:33:12 ubuntu.local ticky: ERROR Tried to add
information to closed ticket (mcintosh)"
 >>> import re
 >>> re.search(r"(ERROR .*?) \(", s).group(1)
'ERROR Tried to add information to closed ticket'

Alternatively, with a lookahead assertion:

 >>> re.search(r"ERROR .*?(?= \()", s).group()
'ERROR Tried to add information to closed ticket'
