I have a code similar to the following:
try:
something()
except DerivedException as e:
if e.field1 == 'abc':
handle(e)
else:
# re-raise with catch in the next section!
except BaseException as e:
do_some_stuff(e)
Where DerivedException is derived from BaseException.
So, like the comment in the code mentions - I want to re-raise the exception from inside of the first except-section and catch it again inside the second except-section.
How to do that?
Python's syntax provides no way to continue from one except block to another on the same try. The closest you can get is with two trys:
try:
try:
whatever()
except Whatever as e:
if dont_want_to_handle(e):
raise
handle(e)
except BroaderCategory as e:
handle_differently(e)
Personally, I'd use one except block and do the dispatch manually:
try:
whatever()
except BroaderCategory as e:
if isinstance(e, SpecificType) and other_checks(e):
do_one_thing()
else:
do_something_else()
Is this what you are looking for?
{ ~ } » python
>>> try:
... try:
... raise Exception("foobar")
... except Exception as e:
... raise e
... except Exception as f:
... print "hi"
...
hi
You just use the raise keyword alone to raise the error that was just caught.
try:
try:
something()
except DerivedException as e:
if e.field1 == 'abc':
handle(e)
else:
raise
except BaseException as e:
do_some_stuff(e)
except will not be caught in any of the excepts that follow it.
