regular expression
I was wondering if anyone knows a goods tutorial on using regular expressions. I have gone through the phython manual and tutorial in the supplied documentation but it is not detailed. Also how would I get everthig after the "hello" in this string using the regular expersion module?
" What a nice day guys. hello it's me Omega " thank you

There is a tutorial at http://www.amk.ca/python/howto/regex/.
The book 'Text Processing in Python' by David Mertz has a chapter on regular expressions. You can find a web copy of the book at http://gnosis.cx/TPiP/. In answer to your second question: Code:
>>> import re >>> s = " What a nice day guys. hello it's me Omega " >>> match = re.search(r'hello(.*)', s) >>> match.group(1) " it's me Omega " The regular expression "hello(.*)" will match the "hello", then assign all the text after it to a group, which can then be extracted from the match object.
