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).
