Thank you Steven, Modulok and Alan for your precious and detailed
explanations!
I understood that I must not overuse try-except statement and usually
when the exception could happen exceptionally.
By the way I have this piece of code using elementTree standard module
and according to Alan this is bad code I guess:
*try: devdb.setDescription(dev.attrib['description'])
except KeyError: pass
[...]
Whenever you have very similar code repeated many times, you should
consider factoring out the common code into a helper function. Something
like this:
def try_or_pass(key):
attr_name = 'set' + key[0].upper() + key[1:]
try:
getattr(devb, attr_name)(dev.attrib[key])
except KeyError:
pass
try_or_pass('description')
try_or_pass('symbolName')
etc.
