Answer: Python Puzzler #1534

The answer is B. The program prints:

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

Why?

First Python works out each side: 3 > 7 is False and 7 < 8 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
3 > 7False
7 < 8True

The code again

print(3 > 7 or 7 < 8)

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