regex python email-validation Python

I need some guidance on I've searched everywhere and can't find a clear answer. This might be a silly question, but I'm having trouble getting my regex pattern to match valid email formats in Python, particularly those that include special characters like `+` and `.` in the local part... I need to ensure that it captures emails such as `user.name+tag@example.com` and also handles edge cases like `user@subdomain.example.com`. I've tried using the following regex pattern: ```python import re email_pattern = r'[a-zA-Z0-9._%+-]+@[a-zA-Z0-9-]+\.[a-zA-Z]{2,}' valid_emails = [ 'user.name+tag@example.com', 'user@subdomain.example.com', 'user@domain.co.uk', 'user@domain', # Invalid, should be ignored 'user@.com' # Invalid, should be ignored ] for email in valid_emails: if re.match(email_pattern, email): print(f'Valid: {email}') else: print(f'Invalid: {email}') ``` However, my output shows that `user.name+tag@example.com` is being marked as invalid. I'm getting confused as the regex pattern seems right, but it just doesn't capture those special characters properly. Can anyone guide to identify what I might be missing or if there's a better approach to validating email formats in Python without missing valid formats? This is my first time working with Python 3.9. Any advice would be much appreciated. I appreciate any insights! This is my first time working with Python latest.
