Answer: Python Puzzler #1698

The answer is C. The program prints:

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

Why?

First Python works out each side: 5 > 4 is True and 4 < 4 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
5 > 4True
4 < 4False

The code again

print(5 > 4 and 4 < 4)

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