The answer is D. The program prints:
pong!boop!ping!zap
This answer was checked by running the program for real.
Why?
join glues the items of a list together, putting ‘!’ between each pair.
The code again
sounds = ["pong", "boop", "ping", "zap"]
print("!".join(sounds))Try it: change one number in the program and predict the new output before you run it.
