Give me your email

A colleague has asked for your help! When a user signs up on the company website, they must provide a valid email address.
The company puts some rules in place to verify that the given email address is valid:

  • The first part can contain:
    • Upper A-Z or lowercase letters a-z
    • Numbers
    • Characters: !, #, %, &, *, $, .

    • But only .com ending is allowed

The project consists of writing a script that checks if the email address follow the correct pattern. Your colleague gave you a list of email addresses as examples to test.
