Find Email Domain

An email address such as "John.Smith@example.com" is made up of a local part ("John.Smith"), an "@" symbol, then a domain part ("example.com").

The domain name part of an email address may only consist of letters, digits, hyphens and dots. The local part, however, also allows a lot of different special characters. Here you can look at several examples of correct and incorrect email addresses.

Given a valid email address, find its domain part.

Example

• For address = "prettyandsimple@example.com", the output should be

  find_email_domain(address) = "example.com"

• For address = "fully-qualified-domain@codesignal.com", the output should be

    find_email_domain(address) = "codesignal.com"

Solution

PYTHON

def find_email_domain(address):
    return address[address.rindex('@') + 1:]


print(find_email_domain('abc@gmail.com'))

JAVASCRIPT

function find_email_domain(address) {
  return address.split('@').pop();
}

console.log(find_email_domain('abc@gmail.com'));
