SyntaxError can happen as a consequence of loading a module (hitting an import statement, etc). But for a simpler example, replace SyntaxError with NameError and it's still almost always a design error that you probably have no sane way to handle in an exception handler (other than to mask the problem).

Python's a very dynamic language and so of course you could come up with examples to the contrary (ones where the user input could trigger SyntaxError or NameError).
