Websites often need to verify an email that is entered by a user for validity. We can verify an email in a few lines of code in Python. First step is to confirm that the email is of the accepted format, to ensure that no random input is accepted as an email. Next is to see whether the email address indeed exists. Due to restrictions in the major email service providers such as Gmail and Hotmail, this code may not work completely. Nevertheless, it gives an overall idea on a given email address.
