Answer: Python Puzzler #1860

The answer is A. The program prints:

False

Checked by running the program for real.

First Python works out each side: 1 > 3 is False and 3 < 3 is False. or is True only if at least one side is True.

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

part	value
1 > 3	False
3 < 3	False

print(1 > 3 or 3 < 3)

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