Faster than trying and except? - Python

Question

I often have code written as follows

try:
  self.title = item.title().content.string
except AttributeError, e:
  self.title = None

---

Is there a faster way to handle this? single line?

Answer 1

What exceptions do you get from item.title()? Naked except(terrible practice!) Doesn’t tell us. If it is an AttributeError (where itemthere is no method title, for example),

self.title = getattr(item, 'title', lambda: None)()

may be the one liner you are looking for (but the performance will not differ from you, -).
