Regular expressions and sub

Hey hey --

I've got a question about regular expression substitions. Basically,
I want to do something like this:

re.sub(r"(stuff )|(blah)", r"I was \00", "stuff blah")

Which would yield the string "I was stuff I was blah" -- but I get "I
was \x00 I was \x00" because apparently the replace string is simply
being interpreted as a normal string, and not a regular expression.

So, my question is, is there a simple way to do what I want?

Thanks much,
John

Here's one way:
re.sub(r"(stuff |blah)", r"I was \1", "stuff blah")

'I was stuff I was blah'

I'm still working on formal documentation, and in any case, such documentation isn't necessarily the...

Hi, I am replaceing a big string using different regular expressions (see some example at the end of the message). The problem is whenever I apply a "replace" it makes a new copy of string and I want to avoid that. My question here is if there is a way to pass either a memory stream or array of "find", "replace" expressions or any other way to avoid multiple copies of a string. Any help will be highly appreciated

I have a regular expression (^(.+)(?=\s*).*\1 ) that results in matches. I would like to get what the actual regular expression is. In other words, when I apply ^(.+)(?=\s*).*\1 to " HEART (CONDUCTION DEFECT) 37.33/2 HEART (CONDUCTION DEFECT) WITH CATHETER 37.34/2 " the expression is "HEART (CONDUCTION DEFECT)". How do I gain access to the expression (not the matches) at runtime? Thanks, Mike

I'm kind of disappointed with the re regular expressions module. In particular, the lack of support for recursion ( (?R) or (?n) ) is a major drawback to me. There are so many great things that can be accomplished with regular expressions this way, such as validating a mathematical expression or parsing a language with nested parens, quoting or expressions. Another feature I'm missing is once-only subpatterns and possessive quantifiers...
