c.l.p-
I am having trouble understanding how one is supposed to correctly
utilize try:...except:...finally: in real code. If I have a block of
code like:
def foo():
try:
... some code that can raise an exception ...
finally:
... do some cleanup ...
return something
If any exception occurs in the code inside the try:...finally:, it will
fail silently, which is a bad thing.
You want:
def foo():
try:
...work...
finally:
...cleanup...
return something
By removing the return from the finally block you will still
automatically raise an exception when something goes wrong.
Having the return in the finally block prevents that from happening.
