Difference between except: and except Exception:

Is there any difference between except: and except Exception: ?

Can except deal with anything that is not an exception?

This is from the doc

If an exception occurs which does not match the exception named in the except clause, it is passed on to outer try statements; if no handler is found, it is an unhandled exception and execution stops with a message as shown above.

You can even be more specific. 

>>> while True:
...     try:
...         x = int(raw_input("Please enter a number: "))
...         break
...     except ValueError:
...         print "Oops!  That was no valid number.  Try again..."

Here, you enter except clause only if you are facing the named error, ValueError

As of Python 2.5, there is a new BaseException which serve as base class for Exception. As result, something like GeneratorExit that inherents directly from BaseException would be caught by except: but not by except Exception:.
