In Python 2.4, this is what's in re.py:

'''
"""Minimal "re" compatibility wrapper.  See "sre" for documentation."""

engine = "sre" # Some apps might use this undocumented variable

from sre import *
from sre import __all__
'''

If you're using CPython, they're the same thing now. Use re, because sre 
is really an undocumented implementation detail of re.
