Answer: Python Puzzler #2970

The answer is C. The program prints:

boop 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 = ["boop", "zap"]
print(" ".join(sounds))

Try it: change one number in the program and predict the new output before you run it.
