Answer: Python Puzzler #3782

The answer is A. The program prints:

False

This answer was checked by running the program for real.

Why?

First Python works out each side: 4 > 4 is False and 4 < 8 is True. 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 > 4False
4 < 8True

The code again

print(4 > 4 and 4 < 8)

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