I am finding myself doing the following a bit too often:
attr = getattr(obj, 'attr', None)
if attr is not None:
attr()
# Do something, either attr(), or func(attr), or whatever
else:
# Do something else
Is there a more pythonic way of writing that? Is this better? (At least not in performance, IMO.)
try:
obj.attr() # or whatever
except AttributeError:
# Do something else
