please use Python

You are to create a program that generates an email addresses.

The format is as follows:

firstname.lastname@domain.topleveldomain (maximum 60 characters) example (aaa.bbb@ccc.ddd)

please use any number of variables and types that you wish. The only requirement is that you ask the user one at a time for first name, last name, domain and TLD (top level domain), use that to generate the email address string. The maximum size of the created email address string is 60. If the email address exceeds 60 you should give the user an error message indicating the generated email address is too long.
