Post funny things about programming here! (Or just rant about your favourite programming language.)
You need to be careful here though. You might not intend for
0
andNone
to mean the same thing.So this won't do the intended thing if a is 0.
Edit: Sorry I meant to reply to the parent comment, realising now you already write the exact same thing.
Also if a is an empty collection or str, or false.
