Heh, did you try the code above? It is a bit surprising (see below).
But I think your solution is cleaner, anyway, in case somebody does something
similar to the above while taking care to re-raise the right exception object.
-------
$ cat a.py
def foo():
raise Exception("foo")
def bar():
raise Exception("bar")
try:
foo()
except:
print 'gotcha! (foo)'
try:
bar()
except:
print 'gotcha! (bar)'
pass
print 're-raising:'
raise
$ python a.py
gotcha! (foo)
gotcha! (bar)
re-raising:
Traceback (most recent call last):
File "a.py", line 12, in <module>
bar()
File "a.py", line 5, in bar
raise Exception("bar")
Exception: bar
