This library validates that a string is of the form x@y.com. This is the sort of validation you would want for an email-based login form on a website.

Key features:

- Good for validating email addresses used for logins/identity.

- Friendly error messages when validation fails (appropriate to show to end users).

- (optionally) Checks deliverability: Does the domain name resolve?

- Supports internationalized domain names and (optionally) internationalized local parts.

- Normalizes email addresses (super important for internationalized addresses!).

This package installs the library for Python 3.
