Full Stack JavaScript Techdegree Graduate 27,070 PointsHow does the else statement work in this example?
I don't understand why exactly the else statement makes the function loop again when we have an error, because there is no if statement preceding it. Does the except statement count as the if in this example and if there is no error, only then it runs the rest of the code, or what is the else in reference to?

I am not looking at the code you are referring to, but I assume you are asking about an else
clause after a try...except
statement in Python. If that's the case, then I can tell you the else
clause is used to contain statements that you only want to execute if the try
clause succeeds. You can think of it as a "no-exception" clause. Of course, if, as part of the exception handling you rethrow, break, or return, then you really don't need an else
clause. But you do need else
if you don't exit the block and you want some statements to execute only if the try
succeeds.
Hope this helps.
Cheers, —Steve
