How similar is Python's re module (regular expressions) compared

Somewhat.
I really hope regular expression syntax is sufficiently standardized
that
we don't have to learn new dialects everytime we move from one
language or shell command to another.
I forgot where I read that so can't back it up but:
"Unices are just a collection of different dialects of regex"
I think the same is true for about every implementation of regex you
can find. In theory it _should_ be same.
Then again, so should SQL but I bet that it's actually quite hard to
find a single statement that you can literally execute it on all DB
servers (major ones).
