Answer: Python Puzzler #937

The answer is B. The program prints:

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

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