What is the point of re-raising exceptions?

Question

So I\'ve seen mention elsewhere of using the following to re-raise an exception.

try:
    whatever()
except:
    raise

What is the purpose

Answer 1

Your example code is pointless, but if you wanted to perform logging or cleanup that only occurs on failure, you could put that between the except: and the raise and you'd do that work and then proceed as if the original exception was bubbling normally.
