Answer: Python Puzzler #1751

The answer is D. The program prints:

5 2

Checked by running the program for real.

// divides and throws away the remainder: each friend gets 5 sweets. % gives the remainder: 2 sweets left over.

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

sum	answer
17 // 3	5
17 % 3	2

sweets = 17
friends = 3
print(sweets // friends, sweets % friends)

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