Answer: Python Puzzler #1844

The answer is D. The program prints:

4 6

Checked by running the program for real.

// divides and throws away the remainder: each friend gets 4 sweets. % gives the remainder: 6 sweets left over.

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

sum	answer
34 // 7	4
34 % 7	6

sweets = 34
friends = 7
print(sweets // friends, sweets % friends)

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