I can't vouch for "all", but the Python reference manual for the "re"
module (http://docs.python.org/lib/module-re.html) says, "This module
provides regular expression matching operations similar to those found

Are you talking specifically about regex, or about the language in
general? If the latter, then the answer is "Yes, and this is a Good
Thing". If you meant the former, then I suspect the answer is that
anything you can do with a Perl regex you can also do with a Python
regex. I'm a pretty heavy regex user, and I've never found anything I
wanted to do which I was unable to.
The biggest difference between regex support in Perl and Python is that
Perl has regex syntax built into the core language, while Python does it
with a module that you have to import and then call functions inside
that module. Which you like better is a matter of personal opinion.
Like most Perl-Python feature comparisons, the Perl version usually ends
up more compact, but the Python version ends up easier to understand.
