Answer: Python Puzzler #2021

The answer is A. The program prints:

rocketrocketrocketrocket

This answer was checked by running the program for real.

Why?

Multiplying a string by a number repeats it. * 4 makes 4 copies, joined together with nothing in between.

The code again

word = "rocket"
print(word * 4)

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