Learning How to Use Regular Expressions to validate email address

Question

I appreciate there is a lot of questions on Regular expressions to validate email address on SO. However, I simply don't understand how to use them to strip out or validate an email address. I have visited multiple sites where the author claims to 99% be able to validate an email address. However, whenever I use an Regular Expression to validate the following I get nothing back

Toranto43.623409,-79.368683 Toranto %6$^2 a.richey@mysite.com

I am completely new to Regular Expressions. So I'm sure I'm doing something wrong, but could someone find a Regular Expression that will find the address a.richey@mysite.com from the above?

What have you tried so far, and where is it going wrong? In what programming language are you attempting to parse / validate? — S3DEV, May 09 '20 at 20:55
That’s great, but please update the question. And please spell Toronto correctly. — S3DEV, May 09 '20 at 21:03
I also tried the regular expression here .. https://stackoverflow.com/questions/201323/how-to-validate-an-email-address-using-a-regular-expression — Carltonp, May 09 '20 at 21:03

The following RegEx worked like a dream:

[a-zA-Z0-9.%+-]*@[a-zA-Z0-9.%+-]*.[a-zA-Z]{2,4}
