Georg Brandl ge...@python.org added the comment:
r'[\w]' also matches word chars. I find that a very useful property, since you
can easily build classes like '[\w.]' It's also impossible to change this
without breaking lots of regexes. It's also explicitly documented, although
IMO it's not
Ezio Melotti ezio.melo...@gmail.com added the comment:
[\w] should definitely work, but [\B] doesn't seem to match anything useful,
and it just fails silently because it's neither equivalent to \B nor to [B]:
re.match(r'foo\B', 'foobar') # on a non-word-boundary -- matches fine

title: re pattern r[\A] should work like A but matches nothing
Ezio Melotti ezio.melo...@gmail.com added the comment:
This happens because \A, \B and \Z are valid escape sequences[0].
If what you mean is that they shouldn't be recognized as such inside a
character class, then I can agree with that.
^ and $ are similar to \A and \Z but they are considered
John Machin sjmac...@lexicon.net added the comment:
@ezio: Of course the context is inside a character class.
I expect r'[\b]' to act like r'\b' aka r'\x08' aka backspace because (1) that

this is obviously a Python OO question:
Since Python isn't stringly typed,
I expect this is an innocent typo, and you mean strictly.

Since Python isn't stringly typed, single-dispatch isn't available per
se. So is the double-dispatch Visitor pattern, which is usually used
in OO systems to implement code generators. So, what is the de facto
method in Python to handle source code generation?
Do you mean strongly typed
se. So is the double-dispatch Visitor
pattern,
Yes, typo, I meant strictly.
Wait, what?
First of all, python is strictly typed in that every object has exactly
one type, which is different from other types. So you can't do 1+2, as
you can in some other languages.
Anyway
Yes, typo, I meant strictly.
Damn, I mean strongly. At least not for identifying which methods to
call depending on the type/s.

Well, I'm most experienced in OO, so writing OO in Python seems like
the way to start with Python. The visitor pattern uses single-
dispatch, that is, it determines which method to call be the type of
object passed in.
Well, then do that. Put the types

I think you meant statically typed.
