RegexdrillSimple email addresses
A regex exercise from Regexdrill. Solve it with a pattern box with live highlighting in your browser, checked against hidden test strings, and it is checked the moment you submit.
The task
The whole line must match. Use this simplified rule: a local part of letters, digits, dots, underscores, plus signs or hyphens; one @; one or more domain labels of letters, digits or hyphens separated by dots; and a final label of two or more letters.
What this exercise teaches
[\w.+-]+@[A-Za-z\d-]+(?:\.[A-Za-z\d-]+)*\.[A-Za-z]{2,} follows the stated rule. Real email rules are much looser; this is a practical filter.
A hint if you get stuck
Build it in three parts: the local part, the @, then labels that each begin after a dot. The last label is letters only.
