How it works
Where regex earns its keep for analysts
It is the fastest way to pull structured values out of messy free text (emails from a notes column, order IDs from a description, dates in the wrong format) and to find the rows that don't match a pattern, which are usually the dirty ones. The same expressions drop into SQL's REGEXP, pandas' str.extract and spreadsheet regex functions.
The flags, quickly
g finds every match, not just the first. i ignores case. m makes ^ and $ match line starts/ends. s lets . match newlines too.
