You’re using Python 2 with Python 3-style print statements. To make it look good, start your code with: from __future__ import print_function Or use the Python 2 form (without parentheses), or even better: switch to Python 3. Now, Codecademy is a peculiar place. They still teach Python 2 (that sucks!) and have a specific teaching style. The way you’re supposed to solve this is to just assign your answers to bool_one through bool_five. You should just type True or False in each blank, using Python to evaluate this expression is kinda cheating. Codecademy will then tell you if you got the right answer. Don’t print stuff you aren’t asked to print. However, you should not depend only on Codecademy’s interpreter. Install Python on your computer and work with that. I also recommend learning using different resources, and learning Python 3. It’s the future. ~~~ On 23 September 2017 at 07:01, Bill <bill_nos...@whoknows.net> wrote: > Your answers appear correct, but you could write Python statements to test > them (or any you encounter in the future).

This outputs "False is false", because you used the variable in your expression. You can just do this: >>> print("s is", s) This will print "s is False". You can also replace your earlier `if` with: >>> print((20 - 10) > 15) (False will appear upper-case, of course.) PS. don’t use semicolons with Python. Avoid eval() as well. -- Chris Warrick <https://chriswarrick.com/> PGP: 5EAAEA16 -- https://mail.python.org/mailman/listinfo/python-list
