Something about RegEx 😟

Small note 📝

I usually avoided this topic when I was learning Python in college 😅. It is now time to learn it 📖.

what is RegEx or Regular Expressions?

It's a series of characters that allow us to check for matches. Eg: E-mail validation in forms

RegEx looks like this: ^[a-zA-Z0-9]+(?:\.[a-zA-Z0-9]+)*@[a-zA-Z0-9]+(?:\.[a-zA-Z0-9]+)*$
