Answer: Python Puzzler #1705

The answer is D. The program prints:

2 1

Checked by running the program for real.

// divides and throws away the remainder: each friend gets 2 sweets. % gives the remainder: 1 sweet left over.

A trace table follows the program step by step. Here’s this one:

sum	answer
15 // 7	2
15 % 7	1

sweets = 15
friends = 7
print(sweets // friends, sweets % friends)

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