Answer: Python Puzzler #3699

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: 4 > 3 is True and 3 < 2 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
4 > 3True
3 < 2False

The code again

print(4 > 3 and 3 < 2)

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