Answer: Python Puzzler #1073

The answer is B. The program prints:

zip-zap
What the program prints
Checked by running the program for real.

Why?

join glues the items of a list together, putting ‘-‘ between each pair.

The code again

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

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