Answer: Python Puzzler #1753

The answer is D. The program prints:

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

Why?

First Python works out each side: 6 > 9 is False and 9 < 8 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
6 > 9False
9 < 8False

The code again

print(6 > 9 and 9 < 8)

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