Answer: Python Puzzler #3819

The answer is C. The program prints:

True

This answer was checked by running the program for real.

Why?

First Python works out each side: 7 > 4 is True and 4 < 7 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
7 > 4True
4 < 7True

The code again

print(7 > 4 or 4 < 7)

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