[Tutor] Re: Speaking of regular expressions

[karl d'adamo]

the second edition of the Friedl book was what i went through for an introduction to regular expressions for python.  i think the python implementation is similar in syntax to the java implementation so a lot of the examples are good.  plus, most of what is covered is the writing of the regular expression itself, and this is universally applicable (with many caveats, of course, depending on the specific tool).

also, the regular expressions howto [1] definitely fills in the syntactic gaps
