Answer: Python Puzzler #3465

The answer is A. The program prints:

True

This answer was checked by running the program for real.

Why?

First Python works out each side: 7 > 2 is True and 2 < 9 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
7 > 2True
2 < 9True

The code again

print(7 > 2 and 2 < 9)

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