A simple loop over lines using Python's `re` package is unlikely to be as fast as an optimized grep. If your inputs are small, the difference might be negligible. But if they're large, the difference might be enormous. And that's not even accounting for just regex engine throughput on its own. ripgrep for example uses rust/regex.
