Answer: Python Puzzler #3691

The answer is C. The program prints:

4 5

This answer was checked by running the program for real.

Why?

// divides and throws away the remainder: each friend gets 4 sweets. % gives the remainder: 5 sweets left over.

Trace table

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

sumanswer
29 // 64
29 % 65

The code again

sweets = 29
friends = 6
print(sweets // friends, sweets % friends)

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