Answer: Python Puzzler #1726

The answer is A. The program prints:

True
What the program prints
Checked by running the program for real.

Why?

First Python works out each side: 9 > 5 is True and 5 < 9 is True. or is True only if at least one side is True.

Trace table

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

partvalue
9 > 5True
5 < 9True

The code again

print(9 > 5 or 5 < 9)

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