I learned about Python regular expressions from the Web documentation
<http://docs.python.org/lib/lib.html>. This describes a module named "re".
Then I saw some code written by a colleague, and he was using a module
named "sre". I checked my Python 2.4.3 installation, and sure enough, I
have a module named "sre" as well as "re". Curious, I fired up an
interactive Python session, and looked to see what the docstrings were for
these modules. And for the "re" module, the help says:
re - Minimal "re" compatibility wrapper. See "sre" for documentation.
and "sre" seems to have the more complete set of docstrings.
So which one should we be using?

Here's what Python 2.5 has to say on the matter:
>>import sre
__main__:1: DeprecationWarning: The sre module is deprecated, please import
re.

That's good. Does "help(re)" still say it's a "compatibility wrapper"? This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics
