faster code for my code

[rob101]

something error, I tried this:

I think that you're confused. grep as I know it, is a command-line utility for searching plain-text data sets for lines that match a regular expression and is a part of Unix type computer operating systems (I can't speak for MS Windows OS, as I don't use it), but so far as I know, there is no Python library of the same name: I stand to be corrected on that, if I'm wrong.

For a regular expression pattern match, I'd use regex:

import re
re.search(<regex>, <string>)
