"if not" presumes I know in advance the answer to my question is going to be false. What if I don't have the answer?

"if not" presumes I know in advance the answer to my question is going to be false. What if I don't have the answer in advance? Perhaps this will be answered later, but what if I have a problem I need to solve where I am evaluating something for which I can't know the answer in advance. I played around in terminal and found that Python won't spit out anything if indeed something in false.

Sam;

As an example of when if not might come in handy would be for something like password checking. If the input is not equal to some value (preferably hashed in a password situation), then return the user to the login stage of the app. Otherwise let them pass on through.

Provide an example of the situation you are thinking of and we can look at it.

Happy coding,
Ken

Thanks Ken! Makes sense. I believe I was overthinking it.
