Other people already said that all builtin exceptions are derived 
from Exception. So using except Exception: xxx, you catch all of 
them. What's left:
- string exceptions: deprecated long time ago, but you might 
encounter them in old code.
- other classes not derived from Exception: still legal, probablly 
not on future Python versions.
If you really have to catch any kind of exception, use a bare except 
clause; you always can retrieve the exception details using
sys.exc_info()
