IN PYTHON 3

Your boss wants you to create a program that can take a user's email from their biography, create a password for the user, and save it into a dictionary for later use. The email will be in the form alphabetic@ucla.edu (no numbers, all lowercase). The username is the characters before the domain name (ie. johnsmith in the email johnsmith@ucla.edu). To create the password, you need to alter the username with ROT13.

ROT13 (rotate by 13 places) is a simple substitution cipher that replaces a letter with the 13th letter after it in the alphabet. For example, "j" is the 10th letter in the alphabet. Altering "j" with ROT13 will get the 23rd (10 + 13 = 23) letter of the alphabet, "w". Likewise, if you altered "w" with ROT13, you will get the 10th (23 + 13 = 46 - 26 = 10) letter of the alphabet, "j". Thus in our example with johnsmith@ucla.edu, the password will be "wbuafzvgu". Save both the username and password in a dictionary.

Input:

The input will be several sentences on a single line containing exactly one email within the biography with the form: alphabetic@ucla.edu.

Output:

Print your dictionary which contains "username": and "password":
