# email slicer
# step 1: get user email address
email = input(‘Please enter your email address: ‘).strip()
# step 2: slice out user name
username = email[:email.index(‘@‘)]
# print(username)
# step 3: slice domain name
domain = email[email.index(‘@‘) + 1 :]
# print(domain)
# step 4: format message
output = ‘Your username is "{}" and your domain name is "{}".‘.format(username, domain)
# step 5: display output message
print(output)
