I would say string.replace() should be a bit faster.
I think the reasons may be historical. For a long time the Zope
documentation listed the join and split members of the string
module, but whoever wrote the documentation the first time around
missed out replace. So anyone coming at Zope from the DTML
direction is likely not to spot the replace method.
Calling _.string.replace requires two attribute lookups and one
python method call. replace itself requires zero or one memory
allocation for the result.
Calling join/split requires four attribute lookups, two python method
calls and n+3 memory allocations where n replacements are made
(1 allocation when n is 0).
So I agree, replace should be faster, although given everything else
that is going on, unless you do a lot of them you probably won't
notice.

RE: [Zope] Underscore Caracter
Hmm.. Shouldn't that be:
_.string.join(_.string.split('asd asd'), ' '), '_')
Or, alternatively (and more intuitively),
_.string.replace('asd asd', ' ', '_')
_.string.replace('asd_asd', '_', ' ')

The second argument is implicit on string.split (it defaults to a single
space). But your way works too.

_.string.replace('asd asd', ' ', '_')

It should be noted that _.string.replace() is not mentioned in the DTML

RE: [Zope] Underscore Caracter
Yep, it's there, but it's not documented.
Basically, anything in the python "string" module should be accessible from
Zope DTML.
Now, who do I have to beat up to get the 're' module added to the namespace
variable??? :)

Yes. Thank you.

It happens to be accessible in this case, but I'd bet there are cases in which methods accessible via modules of the _ namespace have been removed for "safe scripting" purposes.
