Answer: Python Puzzler #1701

The answer is A. The program prints:

5 1

Checked by running the program for real.

// divides and throws away the remainder: each friend gets 5 sweets. % gives the remainder: 1 sweet left over.

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

sum	answer
11 // 2	5
11 % 2	1

sweets = 11
friends = 2
print(sweets // friends, sweets % friends)

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