In redemo you just type the actual regex string, no quotes or r prefix. So if you type into the top text box python\.org and in the middle text box python.org then you will get a match. In your program then you have to type the regex as a string literal so you would type r'python\.org' > > BTW redemo.py can be found in Python 2.4 in Tools\Scripts. > > BTW2 The new book, _Beginning Python: From Novice to Professional_, by > Magnus Lie Hetland, has 16 pages on the re module, pp. 235-251. > > (A question about quoting in a Tutor post: in my 1st paragraph above, how > could I have indicated that I am quoting both > > r'python\.org' and python.org > > without using quotation marks to do so, so as to not confuse the regex?

In my response I set the strings off with newlines and an indent. Angle brackets would probably work fine too. IOW I don't think there is really a convention.
