Exceptions vs Raising Exceptions.

I'm going through the Python learning track and I'm understanding that you write an exception if there is a possibility that the input from the user will be invalid. The next video I'm watching talks about when to raise an exception, but what is "raising an exception" really? What would make you consider raising an exception versus just making a single exception?

Raising an exception means that you aren't just handling it, but raising an error to inform the user that there was in fact an error and whatever they did wasn't allowed. Using except, we can handle errors quietly without the user being aware of it, unless we raise the exception, hope this helps.
