Answer: Python Puzzler #3537

The answer is D. The program prints:

False

This answer was checked by running the program for real.

Why?

First Python works out each side: 7 > 7 is False and 7 < 1 is False. and is True only if both sides are True.

Trace table

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

partvalue
7 > 7False
7 < 1False

The code again

print(7 > 7 and 7 < 1)

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