Explanation to the project:

• The validate_email() function uses regular expressions to validate the email format based on the given pattern.
• The validate_password() function checks if the password meets the specified requirements using regular expressions.
• The register() function prompts the user to enter a username, email, and password. It validates the email and password formats and appends the user data to the "users.txt" file if they are valid.
