Final answer:
The code segment checks the Boolean variable 'rsvp' and prints "attending" if it's True, otherwise it prints "not attending".
Step-by-step explanation:
To determine if someone is attending based on the rsvp status, you can write a simple conditional statement in Python. Here is an example of such a code segment:
if rsvp:
print("attending")
else:
print("not attending")
This code checks the Boolean variable rsvp, which should be either True or False. If rsvp is True, it will output "attending". Otherwise, it will print "not attending".
