Answer: Python Puzzler #116

The answer is C. The program prints:

gadgetgadget
What the program prints
Checked by running the program for real.

Why?

Multiplying a string by a number repeats it. * 2 makes 2 copies, joined together with nothing in between.

The code again

word = "gadget"
print(word * 2)

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