The answer is D. The program prints:
pong...byte...ping...bit
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", "byte", "ping", "bit"]
print("...".join(sounds))Try it: change one number in the program and predict the new output before you run it.
