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? -- View this message in context: http://www.nabble.com/New-Issues-with-REGEX-Greediness%3A-tp24764404p24764404.html Sent from the Python - tutor mailing list archive at Nabble.com. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
