I have no idea what to type into the editor for this “And” practice. The Hint doesn’t help out in any way either. I understand math equations and can work out if an equation is true or false, but what am I supposed to type in the editor after each variable? Is this just an exercise in cut, copy, and paste?

Am I supposed to define the ‘bool_one’ variable as:
bool_one = False and False

or am I supposed to make up an equation? I’m clearly not understanding this whole line of exercises.


#4

No, we are supposed to visually/mentally evaluate that expression and supply what we believe the outcome to be.

False and False

will be False since we know that AND short-circuits on false. Only the first operand is evaluated in this case. We are given mental exercises like this so we gain instant recognition of things like that, and are able to do it in our head.


#5

I agree with Brave - I had no idea what to do here. And I’m not sure that mtf’s answer is correct… I had to go to “solution” which is just to type exactly what’s in the instructions. I’m not sure how that helps me learn it. But I’m new so who knows. :slight_smile:


#6

I agree with gthill, it’s unclear what is required, I tried what mtf suggested and it didn’t work, so in the end I used the solution button and it was a copy paste situation. Baffling.


#7

For the record, I did not give a solution. We are given expressions to visually examine and evaluate in our heads. Look at it, break it down, first the left operand, then the right (if needs be).

Keep in mind that if the first operand is False then we need not continue evaluating. We’re done. The expression is False. If the first operand is True, then evaluate the second. If it is False then the expression is False, else True.

Do this in your head. That’s the bottom line.
