As most of you probably know, you can use else with try blocks:
try:
do_stuff()
except SomeExceptionClass:
handle_error()
else:
no_error_occurred()
Here, no_error_occurred will only be called if do_stuff() didn't raise
an exception.
However, the following is invalid syntax:
try:
do_stuff()
else:
no_error_occurred()
Now you might say that this isn't needed as you can achieve the same
result with
do_stuff()
no_error_occurred()
However, what if I want to use finally as well:
try:
do_stuff()
else:
no_error_occurred()
finally:
cleanup()
and I need no_error_occurred to be called before cleanup? For my actual
use case, I've done
try:
do_stuff()
except Exception:
raise
else:
no_error_occurred()
finally:
cleanup()
This seems very non-Pythonic. Is there a reason why else without except
has to be invalid syntax?
What would be the difference between
try:
do_stuff()
else:
no_error_occurred()
finally:
cleanup()
and
try:
do_stuff()
no_error_occurred()
finally:
cleanup()
?
