In re module what does \.- do in [\w\.-]+?

Question

I am writing a code to search for all the email addresses. I was wondering why I should write it as: '[\w \.-]+@[\w \.-]+' What does \.- do in [\w\.-]?

Does this answer your question? [Reference - What does this regex mean?](https://stackoverflow.com/questions/22937618/reference-what-does-this-regex-mean) — Ken White, May 05 '22 at 02:14

[\w.-] matches either a word character (\w), a dash (-) or a dot (.). This is called a character class.
