[Tutor] New Issues with REGEX Greediness:

[gpo]

Thanks for the replies in the last thread.  I'm still trying to figure out
how Python is handling RegEx.  I'm converting my thoughts from Perl (the
mother of regex) to Python, and expect the same results.  Why are they
different?

Perl:
$line='>Checking Privilege for UserId:
{874BE70A-194B-DE11-BE5C-000C297901A5}, PrivilegeId: {prvReadSdkMessage}.
Returned hr = 0'
$line=~/(\w+)\:.+.{8}-.{4}-.{4}-.{4}-.{12}/;
print "$1"
RESULT:
UserId

This is the result I want.  I'm trying to get the name's of GUID's from log
files.

Python:
line='>Checking Privilege for UserId:
{874BE70A-194B-DE11-BE5C-000C297901A5}, PrivilegeId: {prvReadSdkMessage}.
Returned hr = 0'
(re.search('(\w+)\:.+.{8}-.{4}-.{4}-.{4}-.{12}',line)).group(0)
RESULT
'UserId: {874BE70A-194B-DE11-BE5C-000C297901A5'

How/Why are these results different?  What is Python doing differently in
regex, that I need to adjust to?
