Answer: Python Puzzler #1750

The answer is B. The program prints:

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

Why?

First Python works out each side: 3 > 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
3 > 2True
2 < 9True

The code again

print(3 > 2 and 2 < 9)

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