the grep module has been deprecated for ages (it's been in the lib-old 
non-standard library since at least Python 2.1).  The old grep module 
depends on the regex module, which has been deprecated since Python 1.6, 
and which was finally removed in Python 2.5.

there are no such modules in Python, afaik.

(and that's a question, not a doubt, right?)

if you have Python code that uses the grep module, you can replace it 
with something like:

     import re

     def simple_grep(filename, pattern):
         find = re.compile(pattern).search
         for index, line in open(filename):
             if find(line):
                 print filename, index, line[:-1]

where pattern is an RE-style pattern, not a REGEX-style pattern (see the 
RE documentation for details).
