I was looking for an existing answer to this question, and while I came across this answer specifically about C#, this is a compiler-level thing, and so I'd expect Python might differ here.
Look at these two ways of terminating a function. First the one with the else:
if condition:
return some_val
else:
return some_other_val
Then the one without it:
if condition:
return some_val
return some_other_val
Logically, the two do precisely the same thing, even if condition has side effects. They test condition, then return a value.
Is there a chance that Python 3 optimizes one over the other?
