Why don't we include the original num_tickets input in the try block?

In a previous tutorial, Craig said to put any problematic code into a try: block. Since the input could take a ValueError, why didn't we include it in the try? I guess I'm confused as to where the error is actually taking place in the code (where the assignment doesn't happen).

Since the input just brings in a string, it shouldn't produce a ValueError. However, that might happen when converting the string to a number using the int function. So only the conversion needs to be protected by the try block.
