 Built-in exceptions and easy exception handling is one of the shining features of Python. Technically, errors that happen during parsing are called `SyntaxError`s - these will probably be the most common errors you see, and usually happen because of a mistake in whitespace, a syntax misunderstanding, or a simple typo.
 
-Even if the syntax is correct, errors can still occur when your program is run. We call these Exceptions, and there a many different types (this is a good thing, because the more specifically we know what went wrong, the better we can handle it).

 An un-handled exception is fatal: it will print debugging information (called a traceback), stop the interpreter, and exit your program. However, once you learn to handle Exceptions, you can cover your bases and write programs that are robust in the face of issues.

 You can also use `sys.exit()` from the built-in `sys` library. It's generally not a good idea to pepper `sys.exit()` around your code, as it makes it harder to control when your program exits, but this can be a handy function for controlling how and when your program exits. By default, `sys.exit()` with no parameters will exit with a `0` return code, which, by posix convention, signals success. You can pass an integer to `sys.exit()` if you'd like to exit with a non-zero return code (usually signaling some sort of failure condition). You can also pass a string to `sys.exit()`, which will get printed to the command line, along with a return code of `1`.
 
-`sys.exit()` generates a `SystemExit` exception, which inherits from the master `BaseException` class, which makes it possible for clean-up handlers (such as `finally` statements) to run.
