Answer: Python Puzzler #1383

The answer is D. The program prints:

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

Why?

First Python works out each side: 5 > 3 is True and 3 < 5 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
5 > 3True
3 < 5True

The code again

print(5 > 3 or 3 < 5)

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