Check if email is valid with Python

Level: Beginner

Your task for today is to create a command-line email validator that checks if email addresses follow the correct format, helping you learn pattern matching and string validation.

Project Task

Create an email validator that:

• Takes email addresses as input from the user

• Uses the re (regular expressions) library to validate email format

• Checks for proper email structure (username@domain.extension)

• Displays whether each email is valid or invalid

• Allows users to validate multiple emails in one session

• Provides clear feedback on validation results

• Uses a simple regex pattern to match valid email formats

This project gives you hands-on practice with regular expressions, string validation, and input handling — essential skills for data validation and form processing.

Expected Output

Email Validator
===============

Enter an email address (or ‘quit’ to exit): john.doe@example.com
✓ Valid email: john.doe@example.com

Enter an email address (or ‘quit’ to exit): invalid-email@
✗ Invalid email: invalid-email@

Enter an email address (or ‘quit’ to exit): user@domain.co.uk
✓ Valid email: user@domain.co.uk

Enter an email address (or ‘quit’ to exit): @nodomain.com
✗ Invalid email: @nodomain.com

Enter an email address (or ‘quit’ to exit): test.user@company.org
✓ Valid email: test.user@company.org

Enter an email address (or ‘quit’ to exit): quit

Thank you for using Email Validator!
