Answer: Python Puzzler #1400

The answer is A. The program prints:

1 3

Checked by running the program for real.

// divides and throws away the remainder: each friend gets 1 sweets. % gives the remainder: 3 sweets left over.

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

sum	answer
10 // 7	1
10 % 7	3

sweets = 10
friends = 7
print(sweets // friends, sweets % friends)

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