Answer: Python Puzzler #1406

The answer is A. The program prints:

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

Why?

First Python works out each side: 6 > 3 is True and 3 < 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
6 > 3True
3 < 8True

The code again

print(6 > 3 and 3 < 8)

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