> I am testing it with grep. (i.e., grep -e '(and|or|xor)\s*#' myfile) Well, you asked for the python regexp...different environments use different regexp parsing engines. Your response is akin to saying "the example snippet of python code you gave me doesn't work in my Pascal program".
For grep: grep '\(and\|or\|xor\)[[:space:]]*#' myfile For Vim: :g/\(and\|or\|xor\)\s*#/ The one I gave originally is a python regexp, and thus should be tested within python, not grep or vim or emacs or sed or whatever. It's always best to test in the real environment...otherwise, you'll get flakey results. -tkc -- http://mail.python.org/mailman/listinfo/python-list
