Answer: Python Puzzler #3309

The answer is B. The program prints:

beep pong boop

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

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