Python Bible: Email Slicer - String Index, Format and Print

EmailSlicer.py

# Get user email address
email = input("What is your email address?: ").strip()

# Slice out the user name
user_name = email[:email.index("@")]

# Slice the domain name
domain_name = email[email.index("@")+1:]

# Format message
output = "Your username is '{}' and your domain name is '{}'".format(user_name,domain_name)

# Display output message
print(output)

Thanks!

I updated my previous code. If the user doesn't enter @ and .com information, I showed an error message. I asked the user for a valid e-mail address.
