When I typed   ’ not”A”  == False ’ the result was ’True’ and when I typed ’ not”A” == True ’ the result was ’True’ again. I got similar results when I typed ’ not(2) == False ’ and   ’ not(2) == True ’  which both gave the result ’True’ . When I put the whole left side in paranthesis like this: ’ (not”A”) == False’ and  ’ (not”A”) == True ’ the results were different.

You're negating an expression.


 >>> "A" == False
False
 >>> not "A" == False
True
