Answer: Python Puzzler #1859

The answer is A. The program prints:

False

Checked by running the program for real.

First Python works out each side: 1 > 9 is False and 9 < 7 is False. or is True only if at least one side is True.

A trace table follows the program step by step. Here’s this one:

part	value
1 > 9	False
9 < 7	False

print(1 > 9 or 9 < 7)

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